Answer:
Podemos suponer que este estudiante tiene insuficiencia de la hormona de crecimiento (somatotropina) que la secreta la glándula hipófisis y se encuentra en la base del cerebro. Esta hormona no ingresa a las células en su mecanismo de acción por ser peptídica o no esteroidea.
Explanation:
En este caso presentado se encuentra una situación diferente a lo que sucede en el gigantismo: hay un problema hormonal en donde la hormona de crecimiento es secretada de manera excesiva. Recibe el nombre de acromegalia cuando sucede después del cierre de la epífisis del hueso, luego de la edad de crecimiento.
The span of the moons center has nothing to do with the effect hypothesis, however has a remark with materials on the moon itself.
Since this hypothesis itself did not merged with regards to the arrangement for the lunar center however it emerged as a result of the materials that make up the moon itself in light of the fact that the materials that make up the moon contrasted with our own particular planet looks like an enormous similitude.
Or the answer will be:
If the event that effect the hypothesis is r8ght at that point after the impact material from the surface and mantle of the earth was brushed off into space gathering into the moon. There would be next to no material to shape a gigantic center.
A nephron<span> is the basic unit of the kidneys and one of its functions is to filter substances in the blood and excreting urine. The correct order of where urine flows in a nephron is: </span><span>glomerulus, next to proximal convoluted tubule, then to loop of henle, then to distal convoluted tubule, lastly collecting duct. This process is important in homeostasis.</span>
Answer:
- Interruption in the genetic flow between separated groups
- The emergence of new mutations in each of the groups, and their accumulation in time. Slow and gradual differentiation between populations.
- Genetic divergence by natural selection and reproductive isolation
- Prezigotic isolation mechanisms
Explanation:
Allopatric speciation consists of the geographic separation of a continuous genetic background that can give place to two or more new geographically isolated populations. These separations might be due to migration, extinction of geographically intermediate populations, or geological events. In this speciation, some barriers impede genetic interchange, or genetic flux, as the two new groups that are separated can not get together and mate anymore. These barriers might be geographical or ecological.
The process of allopatric speciation involves different steps that affect organisms:
- The emergence of the barrier.
- Interruption in the genetic interchange
- The occurrence of new mutations and their accumulation in time in each population. Slow and gradual differentiation.
- Genetic divergence by natural selection and reproductive isolation makes it impossible for the two groups to mate even if the barrier disappears.
- Prezigotic isolation mechanisms will be favored by selection if occurs a secondary contact between the new species in formation.
Answer:
deforestation is when an area of trees is cleared. reforestation is when a bunch of trees are planted and grown to revive what once was an area of trees.
