<h3><u>Answer;</u></h3>

A. carbon-14

<h3><u>Explanation;</u></h3>
  • <em><u>Relative dating involves the process of determining the age of an object in comparison to another without determining the absolute dating. It may be defined as a method of determining the age of a fossil by comparing its placement with that of fossils in other layers of rock. </u></em>
  • <em><u>Carbon-14 is a type of carbon that undergoes radioactive decay at a known rate, and thus may be used in relative dating.</u></em>
  • <em><u>The amount of carbon incorporated in an organisms (plants and animals) when its alive stops when an organism die and the amount of carbon-14 begins to decrease at death as it undergoes radioactive decay. This can be used to determine the age of fossils.</u></em>

Which statement best explains why the level of ATP in skeletal muscles changes during exercise?

Two women are comparable in age, body conformation, and are pregnant at the same time, but one experiences stretch marks, while
adell [148]

The question is incomplete as it does not have the options which are:

a. The woman with stretch marks has a greater collagen-to-elastic fiber ratio.

b. The woman may have different gender babies.

c. The woman with less stretch marks has larger skin cells.

d. The woman without stretch marks has more cholesterol in her diet, which affects her cell membranes.

Answer:

The woman with stretch marks has a greater collagen-to-elastic fiber ratio.

Explanation:

The stretch marks on the hips, stomach and breast of pregnant women is a very common problem. These stretch marks appear pinkish in color which is very difficult to treat.

These stretch marks are the result of the collagen to elastin ratio which increases and stretches. This stretching happens due to the sudden or rapid increase in the weight of the body or the affected portion.

Thus, the selected option is correct.

What happens to the phosphates when plants and animals die?
andrew-mc [135]

Answer:

When plants and animals die, organic molecules also undergoes decomposition and this causes the incorporated phosphates to go back to the soil or bodies of water.

Explanation:

Phosphates are naturally related to <u>"phosphorus."</u> <em>They play a vital role in the life of animals and plants. </em>Phosphorus can be commonly be found on the earth's land and water (although the land has a smaller amount of it). <u>Plants naturally absorb phosphate from where they're growing. Animals take up phosphates by eating plants.</u> The phosphate that plants get from the soil are considered inorganic. They only become organic when it is incorporated into the plants DNA (since this is an organic molecule).

So, this means that if there's a sufficient amount of phosphate, there will be more plants on earth as it is also important in the process of acquiring nutrients.

When animals and plants die, all of the organic molecules such as phosphate also breaks down and thus, it falls back to the soil or bodies of water. Then, they are ready to enter another Phosphorus cycle.
