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.

why do heart cells have a higher percentage of mitochondria than liver and pituitary gland cells?

Answers

Answer:

This is because the heart requires large amounts of energy in order to pump blood to the rest of the body. The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.

The heart cells have a higher percentage of mitochondria than liver and pituitary gland cells because the heart requires large amounts of energy in order to pump blood to the rest of the body. 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.

A population of 200 mice contains 168 brown mice. Brown is dominant to gray. How much of the population would be h e t e r o z y g o u s?
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.
