Answer:

D. This is an example of directional selection in which one end of the bell curve is better adapted to its environment than the other end.

Explanation:

Directional selection is when one extreme end of a trait of a population is favored. In this scenario, the trait being discussed is the length of a giraffe's neck with the long necked giraffes having an advantage. Their ability to reach  more food increases their chances of making it to reproductive age and pass on their genes. Therefore, natural selection pressures giraffes to adapt and evolve over time to increase their chances of survival as a species.

How can the ecological footprint model be used to predict how changes in resource consumption might effect Earth’s systems?
Vilka [71]

Answer:

It measures the ecological assets that a given population or product requires to produce the natural resources it consumes (including plant-based food and fiber products, livestock and fish products, timber and other forest products, space for urban infrastructure) and to absorb its waste, especially carbon emissions.

You have a population of 1000 people, and you are looking at the population genetics of a blood marker that has two alleles. The
KengaRu [80]

Answer:

Genotypic frequency (How often the allele combination shows YY, Yy or yy)

YY - 490/1000 = 0.49

Yy - 420/1000 = 0.42

yy - 90/1000 = 0.09

Allelic frequency (How often the allele shows Y or y)

P = Frequency of Y = (490+420)/1000 = 0.91

q = Frequency of Y =(420+90)/1000 = 0.51

The population isn't in equilibrium according to Hardy-Weinberg because p + q is more than one.

Hardy-Weinberg equation is p+q =1

P^2 +2pq + q^2 = 1

The Hardy-Weinberg assumption the population violated is that there is gene flow as seen in the Allelic frequency that is more than 1

Explanation:

When a population is in Hardy-Weinberg equilibrium for a gene, it is not evolving, and allele frequencies will stay the same across generations.

There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection.

If the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change).

tino4ka555 [31]

Answer:

Mutualism

Commensalism

Parasitism

Explanation:

In mutualism, both organisms benefit.

<em>Ex</em>. Sea anemone and clownfish. Clownfish gives the anemone food, the anemone allows the clownfish to use it as a home.

In commensalism, one organism benefits, while the other is neither harmed nor benefited.

<em>Ex</em>. Sharks or whales and remora fish. The remora rides along the belly of whales or sharks and when it eats, the pieces that float around, the remora eats the excess.

In parasitism, one organism is benefited, while the other is hurt.

<em>Ex. </em>Dogs and fleas. The fleas are constantly biting and feeding off of the dog's skin. The dog gets bitten and itches a lot.

Mutualism and commensalism are similar because at least one organism is benefited.

Parasitism and commensalism are different because instead of one organism not getting hurt, like in commensalism, that happens in parasitism.
