wouldn't it he A
Explanation:
because they are not the same species
<h3><u>Answer;</u></h3>
Evolutionary patterns observed in the fossil record are consistent with evolutionary processes occurring today.
<h3><u>Explanation;</u></h3>
- Three spine stickleback is a model organisms for studies in evolution because; Stickleback fish are small and have short generation times. These two characteristics make them easy to keep in a lab and useful for conducting genetic studies, since researchers can follow several generations of fish in a relatively short time.
- Also, stickleback fish populations occur throughout the Northern Hemisphere in a wide range of environments, so researchers can compare different populations and study how they have changed over time in response to different environmental pressures.
Extinction is a natural process that may be caused by natural selection, shortage of food or natural calamities. Hunting, deforestation, pollution, the conversion of uncultivated areas into pastures, the illicit trade of wild animals as well as climatic changes have made life more difficult for many animals.
Well, usually the qn would be what is different between a compound and a molecule. but if you ask like this then, here goes.
An element is the simplest substance that can not be broken down into its components using physical processes. exp: Na, S, K
A molecule is a substance that make up of an element bonded together.
exp: O2, S2, F2(diatomic molecules)
