e glaciers have deposited sand on top of dark soil. In contrast, areas outside Sand Hills have dark soil and dark-coated mice. What explains the different mice populations?
A. Mice living on light-colored sand learned to disguise themselves from predators.
B. Light-colored coats were selected for on light-colored sand.
C. Light-colored mice learned to adapt to light-colored sand.
D. Dark body color became an adaptation in mice on light-colored sand.

Answer:

B. Light-colored coats were selected for on light-colored sand.

Explanation:

  • Natural selection is the process by which nature selects individuals with a particular phenotype that allows them to survive better in the given environment.
  • In the case given, the deer mice with light color coat tare able to survive better on a light colored sand as compared to dark-colored mice, this is because the light colored mice can camouflage on a light colored sand.
  • Camouflaging helps the light colored mice to avoid predators but as the dark-colored mice cannot do so on light colored sand they are more prone to predation and hence are eliminated by natural selection.

The formation of pyrimidine dimers results from which of the following?
umka2103 [35]

Answer:

exposure to ultraviolet radiation is a correct answer.

Explanation:

Ultraviolet light exposure results in the formation of pyrimidine dimers. Ultraviolet radiation damage the DNA by resulting in chemical changes.

Ultraviolet radiation is absorbed by the pyrimidine bases( cytosine and thymine in DNA) and result in the formation of covalent bonds between the succeeding bases.

The formation of the pyrimidine dimers results in the distortions of DNA helix and disrupt the base-pairing during the replication of DNA which results in a mutation.

What evidence supports Hess's theory of seafloor spreading? Check all that apply.
Zarrin [17]

The direction iron in ocean rocks points

The new crust, formed at constructive/divergent boundary (regarding tectonic plate movement), has band-like patterns that orient in different directions (in alignment with earth's magnetic fields) and visible on the surface. This shows that it is newly made crust made from new magma.

Explanation:

These bands are firmed when the iron minerals in magma orient themselves with the earth's magnetic field before the magma cols into rock and lock the minerals permanently in position. This magma upwells from the mantle to fill the void made when the tectonic plates are moving away from each other.

The earth's magnetic field on the other hand is dynamic. Its angle increases gradually from the true north or south and then flips orientation over several hundred years. The iron minerals therefore will align differently depending on the orientation of the earths magnetic field at the time. This is why the new crust has band-like features visible on its surface.

Suppose "A" is a dominant gene for the ability to taste phenylthiocarbamide and "a" is a recessive gene for the inability to tas
dexar [7]

Complete question:

Suppose "A" is a dominant gene for the ability to taste phenylthiocarbamide and "a" is a recessive gene for the inability to taste it. Which couples could possibly have both a child who tastes it and a child who does not?​

a. father AA, mother aa

b. father Aa, mother AA

c. father Aa, mother Aa

d. father AA, mother AA

Answer:

c. father Aa, mother Aa

Explanation:

According to the given information, the ability to taste phenylthiocarbamide is a dominant trait and is imparted by the allele "A". This phenotype would be expressed in both homozygous and heterozygous conditions. The non-taster phenotype would be expressed in the homozygous recessive genotypes only.  

To have both taster and non-taster children, both the parents should have at least one copy of the recessive allele. Among the given options, the father with genotype Aa and the mother with genotype Aa have the possibility to have both taster and non-taster children.

Aa x Aa= 3/4 taster (1/4 AA and 1/2 Aa): 1/4 non-taster (1/4 aa)
