Electrons fill energy levels starting with the levels that are close to the nucleus. The levels are called orbitals and each orbital must be filled before the next orbital can be filled also the 1st orbital can only hold 2 electrons.

Answer:

the production of new living organisms by combining genetic information from two individuals of different types (sexes). In most higher organisms, one sex (male) produces a small motile gamete which travels to fuse with a larger stationary gamete produced by the other (female).

Answer:

a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.

Explanation:

Osmosis is a special case of diffusion. Water, like other substances, moves from an area of higher concentration to one of lower concentration. ... In this example, the solute cannot diffuse through the membrane, but the water can. Water has a concentration gradient in this system....!!!!!!!!!...!!!!!!

Answer:

[tex]f(t)=120+18t[/tex]

Explanation:

We know that for the initial year of a summer camp, 56 girls and 64 boys enrolled.

The total children enrolled for the initial year can be calculated as :

[tex]56+64=120[/tex]

Each year, 18 more students enrolled in the camp.

The variable ''[tex]t[/tex]'' represents the time in years since the camp opened.

The following expression :

[tex]18t[/tex]  

represents the extra children enrolled each year

If we sum, we can obtain the following expression :

[tex]120+18t[/tex]

which is the function [tex]f(t)[/tex] for the total number of students enrolled [tex]t[/tex] years after the camp opened.

The function rule is [tex]f(t)=120+18t[/tex]

For example, when [tex]t=0[/tex] ⇒

[tex]f(0)=120+18(0)=120[/tex]

which is the original amount of enrolled children when the summer camp opened.

When [tex]t=3[/tex] ⇒

[tex]f(3)=120+18(3)=174[/tex]

which is the expected value for the total number of students enrolled 3 years after the camp opened.

I had this question on my test last week

Explanation:

The way people use land can affect the levels of nutrients and pollution in soil. Any activity that exposes soil to wind and rain can lead to soil loss. Farming, construction and development, and mining are among the main activities that impact soil resources.Over time, many farming practices lead to the loss of soil.

And as for land ita the same we construct bulidings and dig mines it damages the land. And as land is imporatant for survival of all the of the biosphere we are definntelt responsible for it as well.

Our water resources face a host of serious threats, all of which are caused primarily by human activity. They include sedimentation, pollution, climate change, deforestation, landscape changes, and urban growth. And again it it affects the biodiversity of water preety badly. The marine animals suffer because of our causes.

Biomagnification occurs when the concentration of a pollutant increases from one link in the food chain to another (i.e. polluted fish will contaminate the next consumer and continues up a tropic food web as each level consumes another) and will result in the top predator containing the highest concentration levels. It starts a chain reaction originating from our doings.

pollutants accumlate in bodies of fishes beacuse, they eat unhygienic and non fishFriendly stuffs,it passes on to onother fish.

Humans have come to rely on fossil fuels to power cars and planes, heat homes, and run factories. Doing these things pollutes the air with carbon dioxide. Other greenhouse gases emitted by natural and artificial sources also include methane, nitrous oxide, and fluorinated gases. It leads to destroying of ozone layer in antartica and durther affecting the biodiversity of animals as well as of ourselves.

Biodiversity is the amount of variety of life on Earth. Healthy ecosystems and rich biodiversity: ... Increase ecosystem productivity; each species in an ecosystem has a specific niche—a role to play. Support a larger number of plant species and, therefore, a greater variety of crops. Even if a single animal is cut from the biodiversity( ie. Extinct) the whole of the food chain will collapse

Threats to Biodiversity. The greatest threat leading to the loss of biodiversity is the human race. As our population grows together with our need for food, water, industry, transportation, and home comforts, it takes over natural ecosystems and replaces them with unnatural.

Identify locations of critical wildlife habitat for species at risk and the threats to these areas. Where possible, eliminate threats and maintain natural areas. Leave critical wildlife habitat undisturbed, especially nesting and denning sites. Promote wildlife use by setting up bird and bat houses. And reduce the no of cars and automobiles there are. Avoid usimg of plastic and toxic substances as it causes further harm to biodiversity.

In the its our fault thw animals are close to extinction or alredy extinct. The least we can so is help to conserve and preserve our beautiful and diverse biodiversity.

The complementary strand of DNA that is made during DNA replication if the template/parent strand of DNA reads ATG GGC CAT is TAC CCG GTA. Thus, the correct option for this question is A.

DNA replication may be defined as a type of biological process through which two identical replicas of DNA form from one original DNA molecule. This process makes a copy of the DNA in a cell is made before the cell divides.

When it comes to the complementary strand of DNA, either of the two chains makes up a double helix of DNA, with corresponding positions on the two chains being composed of a pair of complementary bases.

For example, if Adenine A is present in the parental DNA, then it should be complementarily bounded to the thymine and vice versa. Similarly, if Cytosine is present in the parental strand of DNA, then it should be complementarily bounded by guanine and vice versa.

Therefore, the correct option for this question is A.

Answer:

The intensification of agriculture has caused dramatic declines in farmland biodiversity (Carvalheiro et al., 2013; Senapathi et al., 2015). Since the 1990s, agricultural policies have been developed in Europe to mitigate this loss through agri-environmental schemes (AES). One AES is “sown wildflower strips”, the aim of which is to create new ecological infrastructures by sowing attractive wild flowers on arable land (a few % of the cultivated area). These ecological infrastructures fall within our definition of MIMS since they represent a massive introduction of managed species in the landscape.

Explanation:

complex carb pack more nutrients are simple carbs that are high in fiber and digest more slowly this makes them more ceiling which means a good option to for weight control

The small intestine is where carbohydrates are chemically broken down, instead of the stomach. The disaccharides and pancreatic amylase complete the chemical cleavage of digestible carbs.

The building blocks of large polysaccharides are lengthy, complicated chains of sugar molecules.

Peas, beans, whole grains, and vegetables are examples of foods that are sources of complex carbohydrates. The body converts simple and complex carbohydrates into glucose (blood sugar), which is then used as fuel.

Longer-lasting blood glucose increase and longer-lasting energy elevation are produced by complex carbs.

Therefore, complex carbs are more efficient in giving the body energy, which is the main purpose of carbohydrates.

Answer:

Energy and matter are conserved in cellular respiration because it has identifiable inputs and outputs. These can be modeled with chemical equations.

Food undergoes chemical reactions in organisms to generate new molecules for growth or energy. Therefore, energy and atoms are conserved during cellular respiration.

The law of conservation of energy states that energy cannot be created or destroyed but can be changed from one form to another. The law of conservation of matter states that the total mass within a closed system that does not allow matter or energy to escape should remain constant. However, the law of conservation of energy states that energy can change from one form to another.

The process of cellular respiration is an example of a chemical reaction, which involves the transformation of one type of matter into another. A chemical equation describes this change in molecular structure. This is the cellular respiration chemical equation:

[tex]C_{6} H_{12} O_{6} + 6 O_{2} = > 6CO_{2} + 6H{2}0 + energy[/tex]

(Glucose + Oxygen yields Carbon Dioxide + Water + Energy)

Therefore, the amount of carbon dioxide atoms released by respiration is the same as the amount of  atoms in the oxygen and carbon that were changed.
