Gregor Mendel' research formed the basis of the field of genetics.
The endocrine gland is the ductless gland which produce hormones through diffusion and are transported by the bloodstream.
exocrine gland are transmitted through duct or tube. example is the salivary gland
Since the species is not reaching its maximum population, we can think that there is an inhibiting factor in the ecosystem. So if more organisms were to migrate within the population or if the birth rate were to increase, the population would not follow the trend in the image. If the resources of the ecosystem were limited, the population would increase, but then they would start to die due to lack of resources so the graph would have a gaussian bell distribution.
Therefore, the answer is D, since the maximum load of the ecosystem has been reached and although the organisms continue to reproduce, the population cannot increase but neither does it decrease since there are sufficient resources.
The correct answer is that t<span>here are probably very few astronauts with twin siblings.
We have to take into consideration that astronauts are a very small group of people and that there is only a small chance that one of them has an identical twin. Although the tests can be hard to do and categorize these kinds of tests and measures are not unethical as long the scientists have the person's permission. Currently, we possess the technology and resources to keep a person in space for a year, but it will be really hard to find more astronauts that have identical twins.
