The biological species concept distinguishes two species based on the degree of genetic exchange between their gene pools.

What is biological species concept?

A species taxon is a collection of creatures that may effectively interbreed and give birth to fertile offspring, according to the Biological Species Concept. That idea holds that both interbreeding within a species and reproductive barriers between creatures of various species help to protect the integrity of a species.

The biological species concept (BSC) was created to help people understand biological diversity, notably the widely acknowledged finding that sexually reproducing organisms are more likely to be found in genetic and phenotypic clusters than in a continuum of forms.

Ostrovityanka [42]

Answer:

       <em>P      p</em>

<em>P</em>    PP   Pp

<em>p    </em>Pp    pp

PP=Homozygous purple

Pp= heterozygous purple

pp=homozygous White

Explanation:

I tried to type out the cross. The bold letters are the heterozygous  plants that you are crossing. and the normal letters are the offspring of the two heterozygous parents being crossed. Heterozygous means they are different alleles. Homosygous means the same alleles are present.

heterozygous= Pp

Homozygous= PP or pp

So the egg definitely came first.

Dinosaurs laid eggs, the fish that first crawled out of the sea laid eggs, and the weird articulated monsters that swam in the warm shallow seas of the Cambrian Period 500 million years ago also laid eggs. They weren't chicken's eggs, but they were still eggs.

Which of the following happens to large molecules during digestion?
mel-nik [20]

Answer:

large intestine

Explanation:

Through digestion, large food particles are converted into smaller components that can be readily absorbed into the bloodstream. Sucrose binds to the active site on sucrase, and this puts stress on the bond between the 2 sugars that make up sucrose. The bond breaks, releasing glucose and fructose.
