Jenna says that an example of homeostasis is when body temperature is maintained at about 37°c. Allen says homeostasis is when breathing rate increases along with exercise. Who is correct

Answers

Answer 1
Answer: I think that they are both correct: homeostatis maintains the same internal conditions regardless of the outside environment or activity: these conditions include temperature, as Jenna says, and oxygen level, which is what Allen means.

Answers

The answer is A) the random and independent way in which each pair of homologous chromosomes lines up at the metaphase plate during meiosis I. 

The law of independent assortment is the second Mendel's law. In independent assortment the alleles for different traits are passed independently to the offspring. It occurs during meiosis I. When in metaphase of meiosis I the chromosomes line up, mother's chromosomes can be on one side, and father's chromosomes on the other side of the equator or they can be mixed in a number of ways.

What would most likely happen to the carbon cycle if there were no more plants on Earth?Animals would consume more carbon.
More carbon would be released from fossil fuels.
Carbon would build up in the atmosphere.
Animals would perform more photosynthesis.

Answers

Plants use carbon to live, just like humans use oxygen.  It's a virtuous cycle sine humans breathe oxygen and expel carbon, and plants "breathe" carbon and expel oxygen.

If plants weren't there to "breathe" the carbon, it would just sit in the world, and build up in the atmosphere.
the answer would be ( c ) Carbon would build up in the atmosphere.

Answer:

Behavior

Explanation:

Ethology is a branch of zoology in which zoologist study about the animal behaviour. Ethologists  adopt a comparative method to study the varied form of animal behaviour ranging from -  Sexual selection, aggression, co-operation between two organism, kinship etc.  

Researchers study about both the classical behavior patterns (FAPs – Fixed action patterns) as well as the adaptive changes in behavior brought in by the evolution.
