Answer:

D) Poly-A tails allow eukaryotic cells to export their mRNA from the nucleus and prevent the degradation of the mRNA in the cytoplasm.

Answer:

D

Explanation:

An enzyme called poly (A) polymerase (PAP) is part of the same protein complex that cleaves the pre-mRNA and it immediately adds a string of A nucleotides, called the poly (A) tail, to the 3′ end of the just-cleaved pre-mRNA. The poly (A) tail added protects the mRNA from degradation, aids in the exportation of the mature mRNA to the cytoplasm and helps in binding proteins involved in initiating translation.

Answer:

Bone marrow.

Explanation:

Hematopiesis may be defined as the formation of the blood cells by the precursor stem cells. This process occurs in the bone marrow, thymus and liver.

The red blood cells are enucleated cells with the minimum span of around 120 days. These cells are processed and destroyed in the spleen. The iron is recovered from the red blood cells and sent again into the bone marrow for the production of new blood cells.

Thus, the answer is bone marrow.

How can the random distribution of alleles result in a predictable ratio?
levacccp [35]
Phenotypically and genotypically there are only two different ratios. If you think of a Punett square... 

<span>You could say that a pea plant with the trait for the dominant color green (G) could also carry the recessive trait for yellow (g). So let's say you mate a dominant green, (Gg) with another dominant green, (Gg). You would get 1 (GG), 2 (Gg) and 2 (gg). </span>

<span>Phenotypically (as in physical traitwise), the ratio is 3:1 because you have 3 green colored peas and one yellow. </span>

<span>Genotypically (as in traitwise), the ratio is 1:2:1, because you have 1 (GG), 2 (Gg) and 1 (gg). </span>

<span>So although it's random, for any specific trait there are only 4 different outcomes.</span>

9.If you break an atom apart would it still behave like the element that makes it up? (yes/no)
makkiz [27]

Answer:

Yes.

Explanation:

The energy released in splitting just one atom is miniscule. However, when the nucleus is split under the right conditions, some stray neutrons are also released and these can then go on to split more atoms, releasing more energy and more neutrons, causing a chain reaction.
