The most consistent way to obtain information about the evolution of species is to look at the fossil record. Another is to observe the differences between species currently on earth. Another is to use carbon dating.

A client undergoing a skin test has been intradermally injected with a disease-specific antigen on the inner forearm. The client
yarga [219]

Answer:

Yes, there is a need to assure the client that this is a normal reaction.

Explanation:

In the given case, it is the duty of a nurse to assure the patient that swelling takes place while performing intradermal vaccination. As with the administration of disease-specific antigens, the injected area inflames that generally takes place due to the development of antibodies against the presented antigens.  

Thus, both the patient and the nurse need to be calm in such a situation and should leave the swelling open so that it can get heal by itself. In case, if one applies ice packs or rubs the affected area, it can enhance the condition and may result in more issues.

Can amoeba have offspring with different genes and traits
stepan [7]

Here is your answer

No

______________________________

REASON:

Amoeba reproduces by the process of binary fusion which is an asexual mode of reproduction.

Since, in asexual method mitosis cell division takes place, same DNA material is transferred to the offsprings so no new traits and genes can be found in offsprings.

However in some case due to genetic drift or mutation, slight variations can be found in progeny.

But this is very exceptional.

Round seeds are dominant over wrinkled seeds in
antoniya [11.8K]

Genotype - RR - 25%, Rr - 50%, rr - 25% (1:2:1)

Phenotype - Round seeds - 75%, Wrinkled seeds - 25% (3:1)

<h3>How explain your answer?</h3>

Let the letter "r" stand for the alleles, where R is round seeds and r is wrinkled seeds. A genotype is an individual's genes represented through alleles. Phenotypes are how the genes express themselves. In other words, genotypes will be written using letters, the alleles, and phenotypes will be the possible outcomes of the alleles.

Both of the parent seeds have the genotypes Rr and the phenotype of round seeds.

If you create punnet square (which had four boxes in total) 1 will have RR, 2 will have Rr, and 1 will have rr. These are the ratios for the genotypes. Each box represents 25%, so the percentages will be 25, 50, and 25. Finally, 3 of these boxes (RR and Rr) will result in round seeds because those are dominant. Only the genotype rr will result in wrinkled phenotype. Therefore, the ratio is 3:1 or 75% to 25%.

Thus, this could be the answer.

In addition to destabilizing glucose for subsequent breakdown, what else does phosphorylation of glucose do
V125BC [204]

Phosphorylation of glucose adopt the pentose phosphate pathway.

<h3>What Phosphorylation of glucose do?</h3>

The phosphorylation of glucose maintains the downhill gradient for metabolism of glucose and extramitochondrial glucose flux through the use of pentose phosphate pathway. Induction of the pentose phosphate pathway and the generation of NADPH may also contribute to protection against death of cells.
