Answer:
The answer is given below
Explanation:
The 2 traits of the agouti fur mice are determined by non linked genes, which assort independently.
For this purpose we will use the multiplication rule to calculate the probability of agouti brown offspring (A_ bb) from AaBb parents.
The probability of A_ offspring is 3/4 and the probability of offspring bb is 1/4.
The total probability will be 3/4 x 1/4 = 3/16.
It adjust the concentration of the urine to reflect the body's water needs, conserving water if the body is dehydrated or making urine more dilute to expel excess water when necessary. ADH is a hormone that helps the body to retain water by increasing water reabsorption by the kidneys.
Answer: The body maintains homeostasis by positive and negative feedback mechanism.
Explanation:
The body maintains the internal temperature and metabolism with respect to change in environment.
In case the temperature outside is very cold and the body starts shivering by the movement of skeletal muscles, this is done to maintain the temperature inside body. This is positive feedback.
When the temperature inside the body is maintained, then body stops shivering. This is negative feedback.
This is how the body maintains homeostasis.
