Answer:
The fundamental unit of heredity that carries genetic information from one generation to the next. A gene is an ordered sequence of nucleotides located on a particular position on a particular chromosome that encodes a specific functional protein. ... Each protein has a unique function determined by its shape.
Cells do not function well at PH's High or Low
<h3><u>Answer;</u></h3>
C.) The number of differences in a specific DNA sequence of two species is multiplied by a known mutation rate to determine the number of years of evolution that separate the two species.
<h3><u>Explanation</u>;</h3>
- Molecular clocks are used to date origin of species. They are based on the observation that random mutations accumulate in genes at a fairly constant rate
.
- Once a mutation rate is determined it can be used to establish dates of divergence of species.
- Molecular clocks can be used in putting a series of evolutionary events into chronological order, by comparing sequences from different species to determine when they last shared a common ancestor, in effect drawing the family tree.
The complete statement is "Hypothalamus release CRH , pituitary gland release ACTH, and the adrenal glands release cortisol to complete the action in the HPA axis."
<h3>What is HPA axis events?</h3>
Generally, The key physiological mechanism that regulates the human body's stress response is the HPA axis.
In conclusion, HPA axis cascaded events are
Hypothalamus release CRH
anterior pituitary release ACTH
adrenal glands release cortisol.
