The researchers participating in the experiments described above were assigned to conduct new experimentation, also on Leigh syndrome-positive mouse specimens. As a precursor step, it was decided to create a new population of Leigh syndrome-positive mice. What would be the option most likely to be successful in creating this population
Answer:
Induction of intentional mutations in the mitochondria of pre-fertilization ova
Explanation:
Leigh syndrome is a neurological disorder which affects the motor and mental state of organisms. The Mitochondria is known as the power house of the cell due to its production of energy for use by various cells in the body. Most neurological problems affect the motor and mental state as a result of a mutated mitochondrion. This explains why Induction of intentional mutations in the mitochondria of pre-fertilization ova Is correct.

Explanation:
A population of 40 killer whales lives in a bay that measures 2000 square miles. What is the population density of killer whales?
Answer:
.02
Explanation:
When finding population density, divide the amount of people, animals or things in the region by the total square miles. 40/2000 is .02.
A population is the size of the group of individuals residing at a place. A population of 40 killer whales has a population density of 0.02.
What is population density?Population density is the individual's concentration of a specific species at a particular geographical location. It allows the establishment of the ecosystem and health.
Given,
Number of individulas = 40
Size of the area = 2000
Density = Number of individuals ÷ Size of the area
= 40 ÷ 2000
= 0.02
Therefore, 0.02 is the population density of killer whales.

A biologist is studying a structure that is made up of two layers of phospholipids. What is she most likely studying?
Answer:
Phospholipid Bilayer
Explanation:
The cellular phospholipid bilayer has 2 layers of phospholipids(obviously), but keep in mind that the heads of said phospholipids are hydrophillic(loving water) and the tails are hydrophobic(hating water). This makes the 2 layers line up with heads facing away from each other and tails facing each other. This is so the bilayer can exist in the aqueous enviorment outside the cell as a barrier and inside the aqueous enviorment of the cell to transport materials in and out of the cell.
Answer:
She is most likely studying cell membranes

A rabbit breeder has rabbits that exhibit three different coat colors: dark gray, chinchilla (a lighter gray), and albino. When cross breeding rabbits with these different coat colors, he finds that dark gray is dominant to chinchilla and albino, whereas chinchilla is dominant to albino. These phenotypic outcomes indicate that there are more than two alleles of rabbit coat-color genes and that they exhibit
Answer:
Multiple allelism
Explanation:
Multiple alleles occur whereby three or more alternative form of a gene which in this case study are dark gray, chinchilla (a lighter gray), and albino; are all present at a locus but only two of the alleles can be present in just one organism.
