I believe that both the Bat and Humans have the most recent common ancestor. The reason I say this is because both diagrams show a wrist and arm-like structure. Also, they both hold a similar quality of fingers.

Hope this helps and have a nice day.

Which condition would result in the least evolution as a result of gene flow? a. Very different allele frequencies in different

nikitadnepr [17]

Answer:

c. Unusually high migration variance Individuals that are very successful at migrating to new populations, but cannot mate in the new locations.

Explanation:

Gene flow refers to the movement of alleles between the local populations when individuals form a population migrate into the other population. Gene flow can occur only if the migrated individuals mate successfully with the individuals of the other population. This would add new alleles from immigrant individuals to the gene pool of the population leading to evolution.

If the immigration is not followed by the mating of the immigrants with individuals of the local population, there would not be any addition of new alleles to the gene pool and the population would not exhibit evolution by gene flow.

Answer:

is hypotonic to the protozoans

Explanation:

The constant influx of water from the outside environment of the cell tells that the environment is hypotonic to the cell.

A hypotonic environment is one with a lower solute concentration than the cytosol. Hence, water osmotically moves from the environment into the cells of the protozoans. The water needs to constantly be removed from the cells, otherwise, they will become turgid and lyse away their contents.

just olya [345]

Answer:

d. A gene from an organism can theoretically be expressed by any other organism.

Explanation:

If we talk about genetic code, it comprises the rules through which genetic material of an organism like RNA or DNA is changed into a functional protein through the process of translation.

Every gene is composed of sequence of nucleotide in set of three called codon. Each codon codes for one amino acid for example CCT codes for Proline.

So, coming to the the question that based on the uniformity of genetic code we can conclude that is a genetic codon codes for one amino acid in one organism like human, without any doubt the same genetic codon will code for same amino acid in any other organism like monkey. why? Again because codon is universal.

So based on these facts the best option that can be concluded is A gene from an organism can theoretically be expressed by any other organism.

Hope it helps!
