Chapter 17 The Female Reproductive System

Answers

Answer 1

The female reproductive system includes the ovaries, the fallopian tubes, the uterus, the cervix, and the vagina.

The internal and exterior sex organs that are part of the female reproductive system play a role in the conception of new offspring. The female reproductive system in humans is immature at birth and matures to produce gametes and carry a foetus to term during adolescence.

Vagina: The vagina is a muscular tube that accepts the male reproductive organ during sexual activity and serves as the baby's exit from the uterus during birthing.

Uterus: If an egg was properly fertilised, this organ houses and sustains a growing foetus.

Ovaries: The ovaries are the female gonads that create oocytes.

mutation in the fibroblast growth factor receptor (fgfr) gene results in achondroplasia (dwarfism), which is a dominant condition caused by a single base substitution (ggg>agg) that changes the amino acid glycine at position 480 to arginine (g480r) in the fgfr protein. normally, fgfr is active when fgf binds to it and inhibits excessive bone growth, but the mutant fgfr is constantly active even when fgf is not bound to it. how can gene therapy be attempted to treat achondroplasia?

Answers

The gene therapy can be attempted to treat achondroplasia is by RNAi that knocks down the mutant FGFR expression, Adeno-associated viral (AAV) vector that carries the wild-type FGFR and CRISPR with the wild-type FGFR donor DNA.

Gene therapy is a cutting-edge method for treating or preventing genetic illnesses. Correction of the specific DNA sequence would repair the protein, curing the disease since mutant DNA in genetic diseases codes for mutant proteins.

Gene therapy can make advantage of RNA interference. By blocking the production of the proteins that the genes code for, it is a method for "silencing" genes. It is a form of gene therapy that utilizes the transition between DNA and protein.

AAV-mediated gene targeting refers to the homologous recombination process through which AAV vectors can integrate. Thus, this vector that carries the wild-type FGFR can be incorporated into the achondroplasia patient.

Using the gene-editing tool CRISPR/Cas9, it is possible to add, remove, or modify a specific section of a gene's DNA sequence. Thus, the damaged section of the mutant FGFR's DNA can be removed using this technique.

List the significant events of the light-dependent reaction (ETC). Include which reactants and products are involved. Highlight what will be released as a product and what will move on to the second stage. Be sure to include where the process occurs in the chloroplast.​

Answers

Answer:

The light-dependent reactions, also known as the photoelectric effect or photoexcitation, are a series of chemical reactions that occur in the thylakoid membranes of the chloroplasts in plant cells. These reactions are an important part of photosynthesis, the process by which plants convert light energy into chemical energy.

The key events of the light-dependent reactions include the following:

The absorption of light by pigments such as chlorophyll and carotenoids. These pigments are located in the thylakoid membranes and are able to absorb specific wavelengths of light.

The transfer of electrons from pigments to electron carriers such as NADPH and ATP. This transfer results in the production of NADPH and ATP, which are used in the light-independent reactions to convert carbon dioxide into glucose and other organic molecules.

The pumping of protons across the thylakoid membrane by the enzyme ATP synthase. This creates a proton gradient that drives the synthesis of ATP from ADP and inorganic phosphate.

The transfer of electrons from the electron carriers to oxygen, the final electron acceptor. This reaction produces water, which is a byproduct of photosynthesis.

The end products of the light-dependent reactions are ATP, NADPH, and water. These products are then used in the light-independent reactions, also known as the Calvin cycle or the dark reactions, to convert carbon dioxide into glucose and other organic molecules. The light-dependent reactions occur in the thylakoid membranes of the chloroplasts, while the light-independent reactions occur in the stroma, the fluid-filled region outside the thylakoid membranes

Chemical energy provides our bodies with the energy they need to keep us moving and alive.

They are broken down into simpler molecules, such as glucose and amino acids, which are then either reassembled and stored in various forms, such as glycogen, or consumed as energy. Chemical energy in food is essential for giving our bodies the fuel they require to keep us alive and active.

What is chemical energy ?

Chemical energy is the energy that is released when chemical substances engage in a chemical reaction and change into other substances. Batteries, food, and gas are a few examples of chemical energy storage mediums.

Around the world, we generate heat and power using chemical energy. Methane, natural gas, oil, and petroleum are examples of fossil fuels that we burn to create steam that turns turbines to generate power. On a smaller scale, people also use these fuels to generate heat to warm up dwellings.

Energy is required by all living things, including humans, to power their metabolic processes of development, growth, and reproduction. However, light energy cannot be directly used by organisms for metabolic purposes. Instead, photosynthesis must first be used to transform it into chemical energy.

What is the evidence from Studies 1 and 2 that capacitors and inductors worked in opposite ways?Passage III

A capacitor is the name for a device that stores electrical charge. Capacitance is the amount of charge that a capacitor can hold at a given voltage. In a science class, a teacher instructed her students to determine the charge on a parallel plate capacitor with a fixed capacitance. Students conducted a few different studies with this capacitor.



Study 1

Students constructed an electrical circuit with the capacitor, as shown in Figure 1. The capacitor was initially uncharged.



Students then charged the capacitor and recorded the voltage at specific time intervals. They then used a computer program to help them graph this information, which is recorded in Figure 2.



With this data, students then calculated the current at each time interval and recorded this information in Table 1. The students noted any trends and determined that voltage and current initially change rapidly before leveling out.



Study 2

The teacher then introduced students to an inductor and explained that, contrary to capacitors, which store energy in an electric field, inductors store energy in a magnetic field produced by the current running through the wire. As a result,

inductors oppose changes in current and act opposite of capacitors, which oppose changes in voltage. She then drew a diagram on the board for students, Figure 3.



The teacher then recorded the decay in voltage over time and represented this in a graph for students, as shown in Figure 4.



Finally, she plotted the drop in voltage and increase in current in a chart similar to the one that the students had produced in Study 1 (see Table 2).

Question 1 of 2
What is the evidence from Studies 1 and 2 that capacitors and inductors worked in opposite ways?

As time progressed, capacitor voltage increased while inductor voltage decreased.

As time progressed, capacitor voltage decreased while inductor voltage increased.

As time progressed, capacitor current increased while inductor current decreased.

Answers

The opposition of a capacitor to a change in voltage versus an inductor's opposition to a change in current is one of the key distinctions between the two devices.

What is a capacitor?Once more, a capacitor can be set up in many different ways. With an electric charge on each plate, the most basic design consists of two parallel conducting plates (but a net charge of zero).A magnetic field is produced inside the capacitor by the electric charge on these plates. An alteration in the electric potential across the plates is necessary because there is an electric field. Depending on how much is being charged, this potential difference's worth can vary. One way to express the capacitor's potential difference is as follows:

Δvc = Q/C

Here, C, the capacitance measured in Farads, is only affected by the device's physical design.The value of the charge on the plates will change if a current is flowing into the capacitor. If there is a steady (or low frequency) current, this current will keep adding charge to the plates to raise the electric potential until finally, this potential will operate like an open circuit with the capacitor voltage being equal to the battery voltage (or power supply). The capacitor will behave as though it were not there if there is a high frequency current because the charge will be added to and subtracted from the plates in the capacitor without any charge buildup.

Summarize in your own words how acid rain affects an aquatint environment

Answers

Answer:

The ecological effects of acid rain are in aquatic environments, such as streams, lakes, and marshes prove destructive to fish and other wildlife. Acid rain seeps into the soil, and harbors aluminum from soil clay particles that flow directly into streams or lakes. Acid rain affects aquatic environments in this way, because it can kill fish, which reduces fish populations, ultimately eliminating fish species in a waterbody and decreasing the available biodiversity. Competition for food increases and disrupts the equilibrium of the aquatic environment.

The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes. The more acid that is introduced to the ecosystem, the more aluminum is released.

Some types of plants and animals are able to tolerate acidic waters and moderate amounts of aluminum. Others, however, are acid-sensitive and will be lost as the pH declines. Generally, the young of most species are more sensitive to environmental conditions than adults. At pH 5, most fish eggs cannot hatch. At lower pH levels, some adult fish die. Some acidic lakes have no fish. Even if a species of fish or animal can tolerate moderately acidic water, the animals or plants it eats might not. For example, frogs have a critical pH around 4, but the mayflies they eat are more sensitive and may not survive pH

Dead or dying trees are a common sight in areas effected by acid rain. Acid rain leaches aluminum from the soil. That aluminum may be harmful to plants as well as animals. Acid rain also removes minerals and nutrients from the soil that trees need to grow.

At high elevations, acidic fog and clouds might strip nutrients from trees’ foliage, leaving them with brown or dead leaves and needles. The trees are then less able to absorb sunlight, which makes them weak and less able to withstand freezing temperatures.



Many forests, streams, and lakes that experience acid rain don’t suffer effects because the soil in those areas can buffer the acid rain by neutralizing the acidity in the rainwater flowing through it. This capacity depends on the thickness and composition of the soil and the type of bedrock underneath it. In areas such as mountainous parts of the Northeast United States, the soil is thin and lacks the ability to adequately neutralize the acid in the rain water. As a result, these areas are particularly vulnerable and the acid and aluminum can accumulate in the soil, streams, or lakes.



Melting snow and heavy rain downpours can result in what is known as episodic acidification. Lakes that do not normally have a high level of acidity may temporarily experience effects of acid rain when the melting snow or downpour brings greater amounts of acidic deposition and the soil can’t buffer it. This short duration of higher acidity (i.e., lower pH) can result in a short-term stress on the ecosystem where a variety of organisms or species may be injured or killed.

A population of mountain lions lives in an alpine forest. The mountain lions hunt deer, rabbits, and other prey. As the population increases, which of these events becomes more likely to occur?.

Answers

Answer: Competition for territory and other resources acts to slow the growth rate of the population

Explanation: Mountain lions are solitary animals who live on mountains of colder areas and hunts on prey like deer, rabbits, sheep, and goats. Every mountain lion has its territory and aggressively defend their territory from other members of their population.

So when the population of mountain lions will increase the competition for territory and other resources will also increase and in ecology, we have learned that competition is a negative interaction between two individuals which decreases the chances of survival for at least one individual.

So due to competition growth rate of the population will slow down to decrease the competition. Therefore, the correct answer is B. Competition for territory and other resources acts to slow the growth rate of the population.

While there are benefits to raising a pet, there are also risks involved that many people do not take into consideration. Welcoming an animal into one's home can become a health hazard. So it is important that parents take the appropriate steps to keep their children safetheir furry friends included. That is why children should be monitored when interacting with pets rather than be used as a means of teaching responsibility. Other chores such as mowing the lawn or washing dishes are better for teaching responsibility but caring for pets should not be treated the same way. Pets can carry harmful germs that can make people sick. The diseases people get from animals are called zoonotic diseases, which are caused by infections that are shared between animals and people. It is hard to know which animals could be carrying zoonotic diseases, especially since animals carrying these germs can often look healthy and normal. Due to the possibility of passing on diseases from pets to humans, instances that may seem innocent could turn into something bigger. For example, a dog can transmit a bacterial infection if a dog bites a human, which can be especially dangerous for younger children. Diseases caused from dog bites may be rare, but they still happen enough that it is a potential risk. It is vital that parents take immediate action and consult their family's doctor and receive proper treatment. Having pets can be a wonderful experience, but there are steps families need to take to reduce health risks from animals. Washing hands, keeping pets clean and vaccinated, supervising children during pet interactions, and preventing children from kissing their pets are some steps parents can take to prevent issues from arising due to having pets in the home. Parents should always monitor their children while handling pets as a safety measure.Passage 2adapted from The Power of Petsfrom NIH News in Health Nothing compares to the job of coming home to a loyal companion. The unconditional love of a pet can do more than keep you company. An added benefit is that pets may also help children learn responsibility and how to gauge emotional awareness. Research on human-animal interactions is still relatively new. Studies have shown that the effects of human-animal interactions are mostly positive for the pet and the person. Animals can feel stressed and fatigued, too. So, it is important for kids to be able to recognize signs of stress in their pet and know when not to approach because animal bites can cause serious harm. "Dog bite prevention is certainly an issue parents need to consider, especially for young children who don't always know the boundaries of what's appropriate to do with a dog," explains a veterinarian. Having a pet will help teach children how to build social awareness and learn how to be a responsible pet owner. By including children in the care of a pet, children not only learn how to nurture it but also learn that an animal is more than just a toy that they get to play with. Children get to learn that pets are more of a responsibility that depends on the family for food, shelter, and care. For example, helping to bathe and brush a pet can help reinforce a child's own personal hygiene care, too; therefore, they learn to understand that a living creature needs just as much care as humans do. Simultaneously, they learn that by caring for a pet's hygiene, they help prevent skin conditions from forming and illnesses from spreading. When children realize that their involvement in the care of a pet matters, they learn the importance of responsibility and selflessness. With responsibility, they also gain empathy for other living creatures.What piece of information in Passage 2 is different from Passage 1? A.
