Answer:
Simplified answer: it's actually many systems that work together, just in different ways!
Explanation:
A large part of the body that is responsible for the regulation of temperature is the nervous system. The hypothalamus, which is a portion of the brain, controls the regulation of body temperature. The process that allows the human body to maintain its core temperature is called thermoregulation. The hypothalamus sends signals to various parts of the body, such as the glands and nervous system, when its core internal temperature begins to fluctuate too high or low.
However, the endocrine and the excretory systems also play a role in the regulation of body temperature.

The answer is d.their cells have some differences in the sequence of nucleotides in their nucleic acids
Human and mice is both mammals and have similar structure and metabolism. There should be no big differences in biological or organic molecule. The big differences should be the sequence of the nucleic acids in their DNA. Mice could produce similar protein in human, but the DNA is different.
Answer:
1/2 , no difference to the fraction of the sons
Explanation:
Since the disorder is inherited recessive gene on the X. The woman will be a carrier since her father had G6PD. Therefore her genotype is X Xh
The normal man genotype will be XY
The genotype of their offspring will be
- Daughters XX, XXh
- Sons XY, XhY
Therefore 1 out of the 2 sons(1/2) will have the disorder
If the father had the disorder, it will not change the fraction of the sons because the disorder is on the X chromosome. However one of the daughters will have it XhXh
