6 0

Answer:

According to the picture, during a solar eclipse the moon must be in position A, interposed between the sun and the earth.

Explanation:

A solar eclipse is due to the interposition of the moon between the sun and the earth, which produces that the solar rays do not reach certain points of the planet.

The lunar phase that is shown during a solar eclipse is the new moon phase, because the satellite does not show the side illuminated by the sun. At this point, the moon must be close to the solar orbital plane for the phenomenon to occur.

In a population of rabbits, there are 496 black rabbits and 27 white rabbits. Fur color is determined by a pair of alleles where
Troyanec [42]

Answer:

0.96

Explanation:

It is given that

B is the dominant allele which represents the black color

and b is the recessive allele which represents the white fur.

B being dominant will result into black color fur for genotype "Bb"

Given -

Frequency of black fur allele (p) is 0.8

As per Hardy Weinberg's  first law of equilibrium

p + q = 1\\

Substituting the value of p in above equation, we get -

q = 1-p\\q = 1-0.8\\q= 0.2

q represents the frequency for white fur allele

Frequency of white fur phenotype is

q^2\\= 0.2^2\\= 0.04

Frequency of homozygous black fur phenotype (BB) is

p^2\\= 0.8^2\\= 0.64

As per Hardy Weinberg's second law of equilibrium -

p^2 + q^2 + 2pq = 1\\0.64 + 0.04 + 2pq = 1\\2pq = 1 - 0.68\\2pq = 0.32\\

Combined frequency of homozygous and heterozygous black fur phenotype is

0.64 + 0.32\\= 0.96

Why does a frameshift mutation usually cause more effects during protien sythesis than a point mutation
Levart [38]

Frameshift mutation affects codons downstream the point of mutation. The previous order of 3 nucleotide- sequences (codons) is consequently changed. This, therefore, changes the protein coded by the mRNA transcribed by the mutated DNA region. Frameshifts are mostly due to insertion or deletion mutations.

Are enzymes reactants explain your answer
stepladder [879]

Answer:

A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.
