Answer:
DNA segments are exchanged between two non-sister chromatids during meiosis I.
Explanation:
An exchange of chromosome segments or parts between non-sister homologous chromatids occurs which is also called crossing over. This crossing over occurs in the meiosis I that is responsible for the variation in the offspring produced. The formation of hybrid species occurs due to this exchanged of DNA segments between two non-sister chromatids.
Answer:
The process that changes one set of chemicals into another is called a chemical reaction.
The answer is: lipids store more energy than carbohydrates.
Lipids are the long-term energy storage. This is because they consist of much higher proportion of hydrogen. So, they are easier to store than carbohydrates and have more energy for their weight.
<span>The primary feedback mechanism that the body uses in order to maintain homeostasis is negative feedback.

For example, when you eat something and digest and absorb it, your body will release insulin in order to prevent glucose levels from becoming to high. If any feedback mechanism malfunctions, you have a disease state.</span>
