A client diagnosed with scabies has been prescribed lindane lotion.
AfilCa [17]

Answer:

Answer is E. Apply a thin layer of lotion on the skin from the neck to the soles of the feet.

Explanation:

Scabies are described or known to be small bugs that burrow and  found crawling under the skin. They lay eggs and continue to multiply under the skin.

They cause rash on the skin and severe or intense itching, which normally get worse in the night.

The lindane lotion , when applied on the skin, goes through or enters the skin, and kills the scabies and their eggs.

The scabies do not affect the face of adults and older children.

Which of the following statements is NOT true regarding ATP production in muscles during periods of prolonged energy use, such a
Marysya12 [62]

Answer:

C.In the absence of oxygen, creatine phosphate can drive aerobic respiration pathways for a few minutes.

Explanation:

C. In the absence of oxygen, creatine phosphate can drive aerobic respiration pathways for a few minutes.

This statement  not true for a following reasons.

Firstly,  creatine phosphate directly phosphorylates ATP instead of providing any support for aerobic pathways.

Secondly, creatine phosphate stores are used up in about 15 seconds only. Thirdly, a cell does not need  oxygen deficit for creatine phosphate to be activated, it just needs to be short on ATP.

Why is a 50 percent recovery of single-crossover products the upper limit, even when crossing over always occurs between two lin
34kurt

Answer:

Because of homologous recombination

Explanation:

  • When genes are establish on different DNAs or far apart on the same chromosome, they are classified self-sufficiently and are said to be unlinked.
  • When genes are very close together on the same chromosome, they are said to be linked. That means that alleles, or genetic versions, that are already together on a chromosome will be inherited as a unit more often than not.
  • We can see if two genes are linked, and how closely, by using data from genetic crosses to calculate the frequency of recombination.
  • Using the technique of discovery recombination happenings for numerous gene pairs, we can make link maps that show the order and relative distances of the genes on the chromosome.

  • When the genes are on the same chromosome but far apart, they are classified independently due to crossing (homologous recombination). This is a procedure that happens at the start of meiosis, in which homologous DNAs randomly exchange matching fragments. Crossing be able to connection new alleles in combination on the same chromosome, causing them to enter the same gamete. When the genes are far apart, the crossing occurs with sufficient frequency for all types of gametes to occur with 25% percentage frequency.
  • When the genes are very close together on the same chromosome, the crossing still occurs, but the result (in terms of the types of gametes produced) is different. Instead of being classified independently, genes tend to "stay together" during meiosis. That is, alleles of genes that are already together on a chromosome will tend to pass as a unit to gametes. In this case, the genes are linked
