Answer:

Humans would look exactly alike

Explanation:

An allele which is a variation of a gene which expresses a particular trait(Phenotype).

For example, if humans have a gene for eye color but has different alleles for the color being black or brown for example, their phenotypes are different since the alleles are different.

But, if the alleles for the eye color are all the same, the eye color and every other phenotype would be the same. So, there would be no variations in eye color, height, color of skin etc. So, all humans would thus look alike having one set of genes for the different traits.

Answer:

Cell–cell interaction

Explanation:

Based on the scenario being described it can be said that the developmental process that has most likely been affected are known as Cell–cell interaction. These are the direct interactions that exist between cell surfaces that allow them to communicate with one another. Doing so by receiving signals and initiating transduction pathways. Therefore since these are functions that have been disrupted it's safe to say that the Cell-cell interaction has been affected.

zaharov [31]

3. any trait that confers even a small increase in the probability that its possessor will survive and reproduce will be strongly favored and will spread through the population.

Explanation:

  • Natural selection is a nonrandom process by which biological traits become more or less common in a population as a function of the differential reproduction of their bearers of differences in the rate of survival.
  • Natural selection can act on any heritable phenotypic trait and operate among any entities that reproduce, show inheritance of their characteristics from one generation to the next, and vary in fitness.
  • Natural selection is the machine that drives evolution. It also explains adaptation.

Vilka [71]

Answer:

The phospholipid will form a sphere with the heads inside

Explanation:

Phospholipids are glycerol molecules containing two Fatty acids that is hydrophobia and a hydrophillic negatively charged phosphate.

The phosphate forms the head and the two fatty acids will form the tail

When phospholipid is dropped into a cup of vegetable oil (a lipid). The phospholipid will form a sphere with the heads inside. This is because the heads are hydrophillic and cannot dissolve in the fat hence they will cluster together.
