Answer:
<h2>In prokaryotes both transcription and translation occurs in cytoplasm (they lack true nucleus) while in eukaryotes, transcription occurs in nucleus while translation occurs in cytoplasm.</h2>
Explanation:
1. Prokaryotes do not have nucleus, so both transcription and translation occurs in the cytoplasm, therefor translation start before the completion of transcription.
2. While in eukaryotes, they have true nucleus, and there protein synthesis machinery (ribosomes) and is situated in the cytoplasm.
So in eukaryotes transcription occurs in the nucleus, and after the completion of transcription, mRNA is processed and finally export into cytoplasm for translation.
"<span>The shape of an enzyme determines which reaction it can catalyze" would be the best option from the list, since most enzymes can only do their job if they "fit" into the structure that they wish to enhance, or "speed up". </span>
Didn't you say that the water at 39 degrees is more dense than water at its freezing point? I think the reason organisms would die is because the water already starting to structure in a crystal form, when it starts to freeze into ice. This probably why it kills the organisms, is because the water ceases to allow the organism to function at those temperatures.
Answer:
Polar Bears
Polar bears have white fur which helps aid in camouflaging against the snow. They also have small rounded ears that act as a shield letting no water in to freeze ear drums and reduce heat loss.
Black Bears
Black bears absorb heat through their black skin. Their thick fur and fat act as an insulation and their large bodies reduce heat loss.
They both use their large claws and teeth to catch prey and provide for themselves
Explanation:
If you need any other examples of adaptions of bears let me know because there are a lot I just added the main ones!
C. phenotype. Phenotype is the physical appearance. I use PH and PH to help me remember.
