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.
I think the cause of the illness is Rota-virus. Its a contagious virus that can cause gastroenteritis(inflammation of the stomach and intestines|). Symptoms include severe watery diarrhea, vomiting, fever and abdominal pains. Infants and young children are most likely to get rota virus disease, they become severely dehydrated and can even die.
Answer:
its the deterioration of the environment through depletion of resources such as air, water and soil or in a more simple form: the destruction of ecosystems
Explanation:
Answer:
The open area where the substrate is attached to an enzyme is called the active site.
Explanation:
The active site of an enzyme corresponds to the place where the tertiary structure of this molecule leaves a free space to couple the substrate and be able to catalyze a chemical reaction.
Since the enzyme-substrate complex functions as a <u>key lock system</u>, the active site has a three-dimensional configuration that only admits certain molecules as substrate, which determines its specificity.
