Answer:
pre-zygotic reproductive isolation
Explanation:
<em>The molecules regulate the pre-zygotic reproductive isolation mechanism.</em>
<u>Reproductive isolation generally refers to the variety of biological processes that sustain the formation of new species of biological organisms. </u>
Some of these processes <em>act to prevent fertilization or the formation of zygotes between organisms that are not of the same species</em> (pre-zygotic mechanisms) while others <em>ensure that the product of fertilization is invalid</em> in case the former fails (post-zygotic mechanisms).
Some pre-zygotic mechanisms ensure that there exists no form of mating among organisms that are not of the same species due to incompatible reproductive organs, but where this fails, another pre-zygotic mechanism will act so that that the mating will not lead to fertilization and there will not be formation of zygotes.
The prevention of fertilization between organisms with compatible reproductive organs but of different species is carried out by molecules. These molecules ensure that there are locks and keys in place to prevent the fertilization of the egg by the sperm.
The answer is B, geologic map. the reason is the study of Geological history is <span>The specific science that is devoted to the study of the Earth, particularly the solid Earth and the rocks that compose it. I hope this helps. </span>
The answer is ASSOCIATIVE neuron. The associative neuron connects or links the other two neurons. The two neurons linked by the associative neurons are; The MOTOR neurons and the SENSORY neuron. I hope that helped. Have a nice day
Answer:
Electron Microscope
Explanation:
In contrast to light microscopes, electron microscopes use a beam of electrons instead of a beam of light. Not only does this allow for higher magnification and, thus, more detail, it also provides higher resolving power. The method used to prepare the specimen for viewing with an electron microscope kills the specimen. Electrons have short wavelengths (shorter than photons) that move best in a vacuum, so living cells cannot be viewed with an electron microscope.
There isn't a function. It's like the "crown feather" on a Cockatiel, purely cosmetic.
