ANSWER:
D and E

EXPLANTION:
A: having a light patch of color hair is not harmful, intact there are many people in this world who has light patch of hair (blondes).
B: It just make the mouse eye shape different, but it doesn’t cause harm to the eye so it’s not harmful.
C: Blending in is good, it can help them hide from predators and it will be able to reproduce mor.
D: If it reduce the plant to make food, its harmful because then the plant might not have enough food
E: It’s makes the plant have a higher chance of having a disease which can be harmful for both humans and the plant

FUN FACT:
Mutations can occur during DNA replication if errors are made and not corrected in time

I hoped this helped and have a great day :)

A fruit fly population has a gene with two alleles, A1 and A2. Tests show that 70% of the gametes produced in the population con
IceJOKER [234]

Answer:

Option C

Explanation:

Given ,

A1 allele is carried by 70 % people

Let us assume A1 s dominant genotype

This means p= \frac{70}{100} = 0.7

Thus, frequency of allele in the given population is 0.7

It is also given that the population is in Hardy-Weinberg equilibrium thus

p+q=1\\0.7+q=1\\q = 1-0.7\\q= 0.3

Frequency of fruit fly with genotype A2A2 will be

q^2\\= (0.3)^2\\= 0.09

As per Hardy-Weinberg's second equation of equilibrium

p^{2} + q^{2} + 2pq = 1\\0.49+0.09+2pq = 1\\2pq = 1-0.49-0.09\\2pq= 0.42

Hence, option C is correct

3. The mechanism in which organisms best suited for their environment survive<br> and reproduce.
lys-0071 [83]

The mechanism in which organisms best suited for their environment survive

and reproduce <u>NATURAL SELECTION.</u>

<u></u>

Explanation:

When individuals in a population compete for resources or live in their environment, the individuals with the slightest advantage over the others have an increased chance of reaching maturity and  reproducing to passing down their genes to the next generations.

Natural selection works on the variations of the population to ‘select’ the best alleles of genes in the population that offer an advantage in ‘survival for the fittest’. This how natural selection fits a population to its environment. The greater the variation within a population, the higher its capacity to adapt to changes in the environment.

Drag the labels from the left to the correct locations in the table to contrast r- and K-selection.
Mandarinka [93]
I don’t see any labels, but remember that humans are a great example of a k-selected species. High rates of parental care leads to high survivorship of offspring, and thus negates the need to have large amounts of offspring.

R-selected species are quite the opposite. They produce large amounts of offspring at many intervals in an attempt to maximize survivorship, as they don’t have strong parental involvement with their young. Think of insects.

How would you describe the<br> structure of the cell?
Vinil7 [7]

Answer:

A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things. Now put that into your own words.

When alleles separate independently and do not influence each other it is known<br> as
AlladinOne [14]

Answer:

Mendel's law of independent assortment states that the alleles of two (or more) different genes get sorted into gametes independently of one another. In other words, the allele a gamete receives for one gene does not influence the allele received for another gene.
