Answer:
Option D, we cannot predict what will happen
Explanation:
Complete Question
You are managing two isolated populations of pine marten ( a native mammal) in Maine. Each population has a neutral recessive mutation that codes for fluffier tails. Both start with the allele frequency at 50%. Over a 10 year period, the allele frequency in population 1 increases from 50% to 65%. Over the same period what do you predict will happen in Population 2?
A. the frequency of fluffier tails will increase
B. the frequency of fluffier tails will decrease
C. the frequency of fluffier tails will stay the same
D. we cannot predict what will happen
Solutions -
In the study conducted by Darwin on the pea plants, it was observed that the number of pea plant with recessive traits increased after certain generation of growth.
Here in Population 1, the allele frequency of allele causing neutral recessive mutation has increased from 50% to 65%.
In case of population 2, we are not aware of the current allele frequency of the allele causing neutral recessive mutation. Also we are not aware of the mating pattern, environmental conditions, and any other genetic condition with in the given set of individuals in population 2
Hence, nothing can be said about the population 2
Option D is correct
Answer:
A earthquake happens when rocks along the fracture slowly bend, then suddenly slip, which is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves or you could just say its a seismic event
The statement is - True.
The solvent do contains chlorofluorocarbons (CFC) and hydrochlorofluorocarbons (HCFC) which evaporate and enter the atmosphere. Because they are very light, the CFC and HCFC manage to get very high into the atmosphere, reaching the ozone layer in the stratosphere. They are actually the two substances that are the most damaging to ozone layer, as once they get in touch with it, they break down its structure, thus creating the ozone holes.
The ozone is crucial for the survival of the living organisms on the Earth as it is the layer that manages to stop most of the ultraviolet rays form the Sun to reach the surface. Because of that, these two substances have to be replaced quickly as the ozone layer is becoming more and more damaged, and that can eventually lead to a tragedy
The process being described is electron transport chain.
<h3>What is Oxidative Phosphorylation?</h3>
- Oxidative phosphorylation is a cell energy process where energy is processed through a series of protein complexes that occurs in the inner-membrane of mitochondria.
This series protein reaction is called electron transport chain and ATP synthase that produces larges amount of ATP.
Thus, we can conclude that electron transport chain is a cell energy process that involves;
- Aerobic,
- Takes place in mitochondria,
- Involves electron carriers NADH and FADH₂
- Produces large amount of ATP

Answer:
50%
Explanation:
This question involves a gene coding for eye color in humans. The allele for brown eyes (B) are dominant to blue eyes (b). This means that blue-eyed individual will possess genotype: bb.
According to this question, a blue-eyed man (bb) has children with a brown-eyed woman (B_) whose mother has blue eyes (bb). Since the mother of the brown-eyed woman has a blue eye, this means that the woman will be heterozygous for brown eye (Bb).
Hence, the parents in this question will cross as follows: blue eyed man (bb) × brown-eyed woman (Bb). The offspring/children will have the following genotypes (see attached punnet square); Bb, Bb, bb, bb.
Based on the question, 2/4 = 1/2 of the children will be heterozygous for the eye color trait. That is, ½ × 100 = 50%.
