A. 32%
B. 84%
C. 48%
D. 16%
Answers
The answer is B, yo welcome
The heterozygous population in the population of 200 mice is 84%. The correct option is B.
What is heterozygous?Heterozygous means having two types of alleles for the same type of gene. These alleles show two types of characters for a single gene. An example is a person having an allele of brown and black hair.
The population is 200 of which 168 mice are brown
By the Hardy–Weinberg (HW) equilibrium
q² (bb) = (200 - 168) /200 = 32 / 200 = 0.16
q: √ 0.16 = 0.4
p = 1 - q = 1 - 0.4 = 0.6
p² (BB) = 0.6 x 0.6 = 0.36
Thus, the correct option is B. 84% regarding the heterozygous population.

How does melanoma affect the functions of the skin?
How does jaundice affect the functions of the skin?
Answers
Answer:
Melanoma is a type of skin cancer that develops in certain skin cells called melanocytes. These are the cells that make the pigment (melanin) that colors your skin. When exposed to UV radiation, such as sunlight, the melanocytes make more pigment, causing the skin to darken or tan. Melanoma starts in cells in the skin called melanocytes. These cells are in the deep layer of the epidermis between the layer of basal cells.
Jaundice causes the skin and the whites of the eyes to turn yellow. The higher the bilirubin level, the yellower the skin. Severe jaundice usually also causes itching and bile. Bile is fluid secreted by the liver.
why do heart cells have a higher percentage of mitochondria than liver and pituitary gland cells?

The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.
What is the role of mitochondria in producing energy?The role of Mitochondria in producing energy are in charge of producing energy as ATP. The heart muscle has the highest energetical requirements. Several mitochondria compose these muscle cells because too much energy is needed to pump blood constantly.
Mitochondria are known as the one of the biggest organelles in the cell. They are semi-autonomous organelles surrounded by a double membrane that reproduce by binary fission and contain their own DNA, RNA, and ribosomes. Mitochondria are in charge of aerobic cell respiration, the process by which cells use organic compounds and turn them into energy.
Therefore, The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.
