Due to the potential energy of a
concentration gradient of hydrogen ions across a membrane. The movement
of hydrogen ions across the mitochondrial membrane. A chemist has discovered a
drug that blocks phosphoglucoisomerase, an enzyme that catalyzes the second
reaction in glycolysis.
Answer:
Gray (or Grey) Matter-the darker tissue of the brain and spinal cord, consisting mainly of nerve cell bodies and branching dendrites.
White Matter-he paler tissue of the brain and spinal cord, consisting mainly of nerve fibers with their myelin sheaths.
Explanation:
Answer:
The robins build a nest to protect their young from predators and the egg falling out of the nest. Robins wil take care of their young by feeding them until they’re old enough to survive on their own and fly from the nest. The baby birds usually stay in the nest but do fall if the nest is built in an unsafe enviroment.
Explanation:
Answer:
<u></u>
- <u>Probability that the descendents are able to fly: 3/4</u>
- <u>Probability that the descendents are not able to fly: 1/4</u>
Explanation:
The question is incomplete.
We can build a Punnett square to find the offspring and then determine the probability that the descendents inherit the ability to fly.
- <em>Superman's genotype: Ff</em>
- <em>Storm's genotype: Ff</em>
Write the columns and rows titles:
F f ← Superman's genes
F
f
↑
Storm's genes
Fill in the cells with the possible combinations:
F f
F FF Ff
f Ff ff
Homozygous FF: 1 can fly
Heterozygous Ff: 2 can fly
Homozygous ff: 1 cannot fly
Total: 4
Homozygous FF: 1/4 can fly
Heterozygous Ff: 2/4 can fly
Homozygous ff: 1/4 cannot fly
- Able to fly: 1/4 + 2/4 = 3/4
Since the ability to fly (F) is dominant, the heterozygous Ff descendents are able to fly. That is 3/4.
Only the homozygous ff are not able to fly. That is 1/4.
