Answer:

Metabolism consists of all the energy transformation reactions in an organism. (Ans. B)

Explanation:

Metabolism is defined as the total sum of the chemical reactions which synthesized in every cell of living things and provides energy for formation of new organic materials and vital processes (such as movement, growth, reproduction and development).

In living metabolism, enzyme mediated chemical reactions takes place. Energy which comes from nutrients and solar energy fueling multistep reactions and converting into the molecules which is necessary for maintenance and growth.

Explain why lizards with brown tails are more likely to be eaten by snakes than the lizards with blue tails.
Alina [70]

Answer:

lizard tails with vivid blue reflectance evolved in communities with either weasel or snake predators, which can both detect blue wavelengths. However, lizard tail UV reflectance was much higher in populations with only snake predators, perhaps because snakes can detect UV, yet weasels cannot. Finally, a cryptic brown tail evolved on islands where birds are the primary lizard predator. Because birds have keen visual acuity, a brown, camouflaged tail may be more advantageous.

There are two alleles, B and b, at a gene locus in a population at Hardy-Weinberg equilibrium. The relative frequency of the dom
viva [34]

Answer:

210

Explanation:

Frequency of dominant allele is represented by "p"

and frequency of recessive allele is represented by "q"

Given

p = 0.7

Thus,

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

As per Hardy Weinberg's second equation of equilibrium -

p^2 + q^ 2 + 2pq = 1\\

Substituting the given values in above equation, we get -

0.7^ 2+ 0.3^2 + 2pq = 1\\2pq = 1- 0.49-0.09\\2pq = 0.42

So the total number of heterozygous individual is equal to

0.42 * 500\\= 210

A population of horses has individuals that are either gray or chestnut colored. The gray color allele, G, is dominant over the
Dahasolnce [82]

We solve the problem using the Hardy-Wineberg equation.

We have the frequency for gray trait as p =  = 0.8

∴ p² = 0.64

64 % of the horses are homozygous for the gray trait.

Solving for the frequency of white chestnut trait by using the fact that,

p + q = 1

∴ q = 1 - p = 1 - 0.8 = 0.2

Now we can calculate 2pq in p² + 2pq + q², which is the frequency for heterozygous gray trait,

∴ 2pq = 2 x 0.8 x 0.2 = 0.32

Therefore, in a population of 100 horses, 32% are heterozygous for gray trait.

Hence the total number of gray horses in a population of 100 will be,

32 (heterozygous gray horses) + 64 (homozygous gray horses) = 96 (gray horses)

Hence, 96% of the horses are gray in color.
