Which of the following correctly describes how mitosis and meiosis are similar?
A. Sister chromatids segregate to opposite poles of the cell during both mitosis and meiosis.
B. Crossing over occurs between homologous chromatids during both mitosis and meiosis.
C. Both mitosis and meiosis produce diploid daughter cells.
D. Both mitosis and meiosis produce genetically identical daughter cells.”
The statement that correctly describes how mitosis and meiosis are similar is “Sister chromatids segregate to opposite poles of the cell during both mitosis and meiosis”.
Mitosis and Meiosis both are classified under cell division that tends to take place in humans and certain other animals. Both Mitosis and Meiosis have both differences and similarities in the way they result in new cells with varying goals and slightly different outcomes. Some of the similarities between meiosis and mitosis are:
During both mitosis and meiosis, cells must duplicate their DNA and pull them apart into 2 sets and further place the sets on each end of itself and then divide down the middle part
Both meiosis and mitosis results in fresh new cells depending on the genes of their parent cells
Thus, we can conclude that the statement that correctly describes how mitosis and meiosis are similar is “Sister chromatids segregate to opposite poles of the cell during both mitosis and meiosis”. Hence, option A is the correct answer.

In experiments with competitive barnacle species distributed along upper and lower intertidal zones, researchers found a trade-off between ability to _____ and ability to _____.
In this case, researchers observed a trade-off between the ability to tolerate harsh dry conditions and the ability to colonize deeper water. This type of trade-off can increase the fitness of only one phenotypic trait.
An evolutionary trade-off can be defined as an evolutionary mechanism where a trait can increase its adaptive fitness in the detriment of decreased adaptive fitness in another phenotypic trait.
In trade-offs, the evolutionary adaptive processes cannot optimize a given trait without compromising another.
A well-known example of an evolutionary trade-off is the balance between the number of eggs that a bird can produce in a determined clutch.

Does “survival of the fittest apply to domesticated animals? Why or why not? *
Answer:
Yes.
Explanation:
This survival of the fittest is instinct helps domestic animals live. Just because an animal is domesticated, does not mean that instincts go away. Those instincts like hunting may get suppressed, but not taking away.
Answer:
Survival of the fittest does not apply to domesticated animals. This is because these animals don't live in the wild so they don't have to run after things and kill them. Their food comes out of a tin and is provided by human beings. They don't have any predators so their lives are seldom at risk. Thus, they don't need to be fitter or more powerful than other animals in any way.
Lets take the example of pet dogs. We keep them for our support or simply because we enjoy their company. We provide them with food, shelter etc. and protect them. Since, we basically do everything for them; they need not evolve into a stronger, more powerful species.
However, in the case of stray dogs, they have to fight for their survival. They have to fight with other dogs for food and shelter. Hence, survival of the fittest will apply here as the strongest dog gets to eat.
Hope this helps.

How do the oxygen (O2) and carbon dioxide (CO2) levels change over time?
What is always true about the total amount of O2 and CO2 in the test tube?
What happens when the CO2 reaches zero?
Answer:
Over a vast amount of time, millions of years, the earth gradually cooled. When the temperature dropped enough, water vapor condensed and went from a gas to liquid form. This created clouds. From these clouds, the oceans formed and the oceans absorbed a lot of the carbon dioxide in the atmosphere.

Mitochondria
Vacuole
Endoplasmic reticulum
Cell wall
Chloroplasts
Ribosomes
Cytoplasm
Are the following organelles found in plant cells, animal cells, or both?
Nucleus
Cell membrane
Plasma membrane
Mitochondria
Vacuole
Endoplasmic reticulum
Cell wall
Chloroplasts
Ribosomes
Cytoplasm
Answer:
Explanation:
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information
The the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions.
The plasma membrane is the same as a cell membrane
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate
Vacuole. A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.
A ribosome is a cellular particle made of RNA and protein that serves as the site for protein synthesis in the cell. The ribosome reads the sequence of the messenger RNA (mRNA) and, using the genetic code, translates the sequence of RNA bases into a sequence of amino acids.
The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell. All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell.

what is the importance of predation in an ecosystem
Answer:
Without predatation, things wouldn't eat each other.
Rabbits won't eat grass, Wolves won't eat Rabbits, and so on...
If it were to continue this way there wouldn't be a single animal on this planet. (everything living except plants that only rely on the sun.)
It's a food chain. A CHAIN. Each varible depends on each other.
And a food chain has a direct impact on the ecosystem.
For example:
No rabbits mean there is so many grass and carrots left behind
No wolves means there are too many rabbits
So that means
No wolves
Whatever eats the wolves wont be alive
Whatever eats THAT wouldn't be alive

what evidence can be cited from the fossils to reconstruct climate change over time?
Answer: When studying the museum’s collection of plant fossils for information about the climate, Wing and Barclay start with plant leaves.
Roughly 56 million years ago, during a time called the Paleocene Eocene Thermal Maximum (PETM), Earth’s average temperature rose four to eight degrees Celsius in less than 10,000 years. The cause was geologic processes releasing trillions of tons of carbon dioxide into the atmosphere. The dramatic shift in global climate forced massive upheaval in ecosystems around the world.
“It’s the best analogue for the climate change we’re experiencing today,” Barclay said.
Fossil plants and their leaves from the PETM show that ecosystems shifted massively because of the rapid increase in global temperature. But global warming during the PETM did not come from humans. So, scientists today are working on ways to extrapolate information from that period and apply it to the even faster and more drastic events of today.

Both the mother and father of a son with colorblindness have normal vision. From whom did the son inherit the gene for colorblindness
Answer:
The blind son inherited his gene for colorblindness from his father.
Explanation:
The X chromosome is where color blindness is most frequently inherited as a recessive trait. In genetics, this is referred to as X-linked recessive inheritance. As a result, men tend to be affected by the illness more frequently than women (8% male, 0.5% female).
What are the characteristics of colorblindness inheritance?There is a 50% chance that the sons of a color-blind father and a mother who has the gene will also be color-blind. However, their daughters will have a 50% risk of having the condition and a 100% chance of carrying the gene.
The 23 chromosome is known as the “sex chromosome,” and it is passed from mother to son. Red/green color blindness is the most common type of this condition.
As it aids in identifying sex, the 23rd chromosome is known as a sex chromosome.
Therefore, The blind son inherited his gene for colorblindness from his father.
