Answer: An external factor caused damage to the nerve cells. However, the injection of new cells into the injured area prompted a beneficial change. The injured cells received proteins that decreased inflammation and pain in the mice.
Answer: Homeostasis
Our body temperature stays constant no matter the changes that may occur in the outer environment - for example, a hot summer afternoon or a cold winter morning. This is an example of homeostasis
Explanation:
Homeostasis is the maintenance of a stable internal environment. Hence, the body maintains a stable temperature, ph level, water-salt balance etc, necessary for healthy development based on the effects of the hormonal and nervous systems.
Answer:
D
Explanation:
The presence of homeotic genes shows that all of the listed organisms (mice, flies, humans etc) all evolved from a common ancestor.
(A) is wrong as the evidence of the same gene existing in vastly different species shows the evolutionary relationship between these organisms.
(B) is wrong as there is insufficient evidence to prove that flies are the precessor of humans. We do know that flies and humans have evolved from a common ancestor though.
(C) is non-conclusive as the passage said nothing about the gene allowing the species to have a higher chance of surviving and reproducing. Hence, an errornous claim.
(D) is the correct answer as from a common ancestor, all of the listed organisms undergo and accumulates mutation, undergoes selective pressures that resulted in divergent evolution (aka branching evolution that results in many noval species forming) after millions of years.
Every time when there is a full moon, Mrs. Cook insists that students in her classes display strange behavior and the best way for her to prove the validity of her theory is to research data to find concrete evidence of a link between the moon cycle and human behavior. Hope this helps. The answer is B
