The enzyme polyadenylate polymerase catalyzes the addition of adenosine
monophosphate to the 3'ends of mRNAs to form a poly-A tail If the enzyme were
blocked so that it could not function, the result would be.

A.) increased mRNA stability in eukaryotes and decreased mRNA stability in
prokaryotes

B.) no effect in eukaryotes and decreased mRNA stability in prokaryotes

C.) no effect in eukaryotes and increased mRNA stability in prokaryotes

D.) decreased mRNA stability in eukaryotes and no effect in prokaryotes

i think its c. amphipod

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.

the rocks are classified by the geological process they are formed by. the three main groups of rocks are igneous, metamorphic, and sedimentary. minerals are not they are classified under the chemical classes they are in. these groups include silicates, sulfates and carbonates.
