Answer:
No se producen consecuencias si las vitaminas se toman en el rango normal.
Explicación:
La caída del cabello, el malestar gastrointestinal, la fatiga y el daño leve a los nervios son algunas de las consecuencias que se pueden obtener si se toma demasiado selenio. Las vitaminas son esenciales para la salud porque nuestro cuerpo las necesita para crecer y desarrollarse. Si estas vitaminas se usan en un rango normal, causan un buen efecto en el cuerpo, pero si tomamos demasiadas vitaminas, causa toxicidad y conduce a una serie de enfermedades. Entonces, si la concentración de vitaminas está en un rango normal en la leche desnatada, tiene un buen efecto en nuestra salud, de lo contrario, causa un problema.
Answer:
Allopatric speciation
Explanation:
Speciation is the gradual process by which two different species are formed from a single species due to evolution.
Allopatric speciation will occur when the speciation is due to geographical isolation of a species to the extend it prevents or interferes with the gene flow. Therefore, the populations can not mate with each other and they evolve separately.
This is what happened to the fox species when they were separated by a mountain range.
I believe the awnser is B
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger and as volume increases, surface area to volume ratio decreases. The larger a cell, the less easily it can get rid of waste and it also has more trouble getting water, nutrients and gases in. That is why we do not see giant cells. Instead we see multiple cells in larger organisms.
One way to increase surface area is to flatten the cell. That is why red blood cells are flat discs, instead of spheres. Another way is elongation. That is why many bacteria are rod shaped, and why neurons are elongated. In fact, the human body relies on the same principle to adapt to climate. Long tall and lean folks with long arms and legs live in East Africa, because such shapes increase surface area to get rid of excess body heat to avoid heat strokes. Europeans and Asians adapted to cold climates, in contrast, have shorter arms and legs and rounder torsos to minimize surface area. to conserve body heat.
