21. Explain why the parent cell and both daughter cells must have the same number of chromosomes after mitosis is over

Quando uma célula somática se multiplica para dar origem a duas células-filhas, ela o faz a partir de um processo conhecido como mitose. Ou seja, as duas células-filhas mantém o mesmo número de cromossomos da célula-mãe.

answer///island,peninsula;

answer;

a. sheep consumption efficiency would be reduced.

explanation;

-trophic efficiency is a measure of how much energy occurs at one level divided by the energy at the level immediately below it . trophic efficiency incorporates three types of efficiency:

-the proportion of available energy that is consumed (consumption efficiency).   it is the proportion of the available biomass that is ingested by consumers.

-the proportion of ingested food that is assimilated (assimilation efficiency).

-the proportion of assimilated food that goes into new consumer biomass (production efficiency).

-in this case, the grasshoppers would affect sheep by reducing the proportion of the available biomass that is ingested by the sheep.
