Define negative feedback of homeostasis
Nadya [2.5K]

Answer:

A negative feedback loop is a reaction that causes a decrease in function. It occurs in response to some kind of stimulus. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or equilibrium, as in mechanics.

Suppose the human trait for dimples is controlled by a simple dominant and recessive relationship at one locus. Dimples, D, is t
Alex

Answer:

a. Frequency of D =  0.223

b. Frequency of Dd = 0.347

Explanation:

n= 131 students

Dimples (DD or Dd)= 52 students

No dimples (dd)= 79 students

Applying the Hardy–Weinberg equilibrium, the frequency of the recessive allele d is found by:

d=\sqrt (dd)\\d=\sqrt(\frac{79}{131})\\d= 0.777

d=0.777

Therefore, the frequencies of the dominant allele, and the heterozygous genotype (Dd or dD) are:

D= 1 -d=1-0.777\\D=0.223\\F(Dd\ or\ dD) = 2*D*d\\F(Dd\ or\ dD) = 2*0.777*0.223\\F(Dd\ or\ dD) = 0.347

a. Frequency of D =  0.223

b. Frequency of Dd = 0.347

The main factor would be the amount of vegetative matter the moose could consume. Other factors would be competition with other species over food source as well as genetic diversity in the case of disease, and other tertiary animals that prey on moose besides wolves.
