m. Prokaryotic mRNA also has a poly-A tail. Choose the best explanation of the prokaryotic poly-A tail.

B. Prokaryotic poly-A tails are composed of a different molecular structure compared with eukaryotic poly-A tails.
C. Prokaryotic poly-A tails aren't important, because prokaryotes don't have nuclei.
D. Prokaryotic poly-A tails have other functions, because prokaryotes don't have nuclei.

Answer: I believe the answer is D. Prokaryotic poly-A tails have other functions, because prokaryotes don’t have nuclei.

Reasoning: A prokaryote is a unicellular organism that lacks a membrane-bound nucleus, mitochondria, or any other membrane-bound organelle. Thus the prokaryotic poly-A tail can not serve the same function as a eukaryotic poly-A tail.

<span>Basically both operate by bouncing tiny particles or waves off of objects in order to make them visible. Electrons are smaller than light photons so we can see smaller objects clearly with electron microscopes. There are disadvantages though. First, color is a function of light wave frequency so we can't see electron micrographs in color. Color can be added artificially though by computer to differentiate structures, (think photoshop). Also, we cannot see electrons so we make them visible by bouncing them off a cathode ray screen similar to a TV set or computer monitor</span>

Which statement best describes the social status of women in ancient Egypt? Women were viewed as the lowest social class. Women
Usimov [2.4K]

Answer:

In ancient Egypt, women were given many of the same rights as men.

Explanation:

The women in ancient Egypt were in no way seen as the lowest social class, so this statement is not correct.

The women were allowed by law to do pretty much everything as the men, so their status was not dependent on their husbands, so it is not a correct statement.

The women were equal in front of law in ancient Egypt, as well as being able to do the same things as men, so this statement is correct.

Women did not have the same status as their fathers, so this is not a correct statement.

<span>The mechanism that affected the gene pool of the immigrants that entered the United States through Ellis Island from 1892 to 1954 is B. gene flow. Gene flow is the transfer of genes or alleles from one population to another. The migration of millions of individuals from countries across the Atlantic Ocean to the United States is responsible for the changes in the gene pool of the immigrants.</span>
