If the conclusions do not support their hypothesis they would start the experiment all over again and see what they did wrong. <span />
Answer:
Results in the evolution of the species: Directional selection
Results in new species: Disruptive selection
Favors traits at the two extremes: Disruptive selection
No increase in diversity: Directional selection
One extreme trait is favored: Directional selection
Diversity decreases: Stabilizing selection
Diversity increases: Disruptive selection
Explanation:
Directional selection which is also known as positive selection is known to be a mode of natural selection. In this type of selection, an extreme phenotype is favored over other phenotypes. This makes the allele frequency to move in the direction of that phenotype and this takes place over time.
Disruptive selection (known to be diversifying selection) talks about the certain changes in the population genetics whereby extreme values of a particular trait are favored over intermediate values. This results in new species.
While Stabilizing selection is a natural selection whereby there is a stabilization of the population mean on the particular value of a non-extreme trait. Here the diversity is decreases.
In each ventricle is a blood vessel network called the choroid plexuses that produces cerebrospinal fluid. This blood vessel consists of ependymal cells
Answer: A
A hypothesis requires your thinking and some background research to prove your thinking. If you do not do background research, then your thinking will not have backup research.
Hope this helps you!
The main significance of an eyespot in the cell of euglena is the detection or sensing of light and then orienting the organism away from or towards the light. Euglena is basically a genus of a single celled flagellate. I hope that this is the answer you were looking for and it has come to your help.
