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%
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.

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

An ocean pH change from 8.2 to 8.0 is NOT significant as the .2 change is very small.
So far, the ocean's pH has dropped from about 8.2 in preindustrial times to around 8.05. This seemingly small change may already be affecting ocean organisms and future CO2 emissions could lower ocean pH even further
in gel electrophoresis, a loading dye is usually added to the sample of dna to be loaded in the wells of the gel. why would this be important?
Answer:
Gel loading dye is typically made at 6X concentration (0.25% bromphenol blue, 0.25% xylene cyanol, 30% glycerol). Loading dye helps to track how far your DNA sample has traveled, and also allows the sample to sink into the gel. ... It is important to use the same running buffer as the one used to prepare the gel.
why is bromophenol blue added to the individual dna samples?
Answer:
It allows the observer to view how far the DNA samples travel.
