The time periods of the Paleozoic and Mesozoic are subdivided into early, middle, and late unlike in the Cenozoic because the number of fossils discovered outnumbers the quantity needed to subdivide the periods based on the presence of organisms.
<span>Early, middle and late time are geological times. Time periods were subdivided because of the major evolutionary events in the fossil record during the Paleozoic and Mesozoic era. </span>
Under Mesozoic:
<span>· </span>Cretaceous
<span>· </span>Jurassic and
<span>· </span>Triassic
Uner Paleozoic:
<span>· </span>Permian
<span>· </span>Carboniferous
<span>· </span>Devonian
<span>· </span>Silurian
<span>· </span>Ordovician and
<span>· </span>Cambrian
<span>While in Cenozoic we have the tertiary or mammals diversity only.</span>
Answer: I'm not sure what the question is, given there aren't any images provided to choose from, but a ribosome looks something like the picture I attached. Good luck!
Explanation:
At room temperature and normal atmospheric pressure, covalent compounds may exist as a solid, a liquid, or a gas, whereas ionic compounds exist only as solids. ionic compounds exist in stable crystalline structures. therefore, they have higher melting and boiling points compared to covalent compounds.
Answer:
Hope this helps!
Explanation:
Arterial blood carries oxygen, nutrients, and hormones for the cells. To reach these cells it leaves the small arteries and flows into the tissues. This fluid is now known as interstitial fluid and it delivers its nourshing products to the cells. Then it leaves the cell and removes waste products.
