The survival rate is a measure of the fitness of each species. Option A is correct. Green beetles are more fit for the environment than brown beetles are.

<h3>What is fitness?</h3>

Fitness or Aptitude can be defined as the contribution of each genotype to the next generation.

Fitness is reflected by the phenotype that results in the survival, fertility, and capability of having a mate.

It is a way of measuring the individual ability to leave fertile offspring.

Aptitude must be significant to the natural selection act in its favor.

In the exposed example we can see the survival rate of two species.

The survival rate is telling us about the fitness of each species.

The green beetle increases its survival rate (fitness) each year

The brown beetle decreases its survival rate each year

These results lead us to believe that the Green beetles are more fit for the environment than brown beetles are. Option A is correct.

Answer:

The answers are:

Cell Wall:

Gives plant cell its shape
Rigid

Cell Membrane:

Acts like a skin.
More selectively controls what goes in and out of cell.
Is not rigid.

Explanation:

The question entails the structural and functional differences of the cell wall and cell membrane.
The cell wall is a rigid and strong layer that covers the outside of plant cells. It is absent in animal cells.
The cell wall is largely composed of cellulose, hemicellulose and pectin in plants and peptidoglycan in bacteria. The cell membrane, on the other hand, is comprised of a lipid bilayer.
The strong and complex network of cellulose renders the cell wall rigid; whereas, as it is made up of lipid bilayer, the cell membrane is flexible and elastic.
Unlike the cell membrane, which allows the movement of selective substances, the cell wall does not allow any substances to pass through.

The frequency of sickle-cell anemia, an autosomal recessive condition, is 0.007. Assuming that the population is in H-W equilibr

damaskus [11]

Answer:

The correct answer is - 0.084

Explanation:

Sickle cell anemia is a autsmal recessive blood disorder of RBCs where RBC shape altered to the sickle shape or cresecent moon that obstruct and damage the veins and artries.

Normal allele is represented by - HbA - p

sickel cell allele is represented by - HbS - q

genotype frequency of normal allele HbA in the population = p2

genptype frequency of HbAHbS in the population = 2pq

genotype frequency of autosomal recessive HbS = q2 = 0.007 (given)

So, the allelic frequency of the recessive allele =

q = √ 0.007 = 0.08366 or 0.084

Students are studying the rate of yeast fermentation under different conditions. Glucose is a monosaccharide. Sucrose is a

Akimi4 [234]

Answer:

The correct option is B. Fermentation would occur at a similar rate to that of glucose.

Explanation:

Fermentation can be described as a process in which alcohol is released by using sugars. In fruit juices, fructose is present mainly to get the sweetness. It is used as a substitute for glucose because fructose is more sweeter than glucose. Both fructose and glucose are monosaccharides with the formula C6H12O6. The only difference is in the arrangement of molecules in the atoms of these compounds. Hence, the rate of fermentation would be same for these two sugars.
