Glucose-6-phosphate dehydrogenase deficiency (G6PD) is inherited as an X-linked recessive gene 43) in humans. A woman whose fath
LiRa [457]

Answer:

50% or 1/2. The result remains unchanged if the husband were to have G6PD.

Explanation:

For X-linked recessive inheritance, a female (XX) needs two recessive alleles to be affected while a male needs only one (XY). It is hypothetically assumed that the Y chromosome does not carry any trait.

Assuming the allele for the disease is represented by g, a woman whose father suffered from G6PD is a carrier for the disease with genotype X^GX^g. A normal man will have the genotype X^GY. When the 2 marries:

X^GX^g   x   X^GY = X^GX^G (normal female), X^GY (normal male), X^GX^g (carrier female), X^gY (affected male)It thus means that 50% or 1/2 of their sons will be expected to have G6PD.

Now, assuming the husband has G6PD, the mating becomes:

X^GX^g   x   X^gY = X^GX^g (carrier female), X^GY (normal male),  X^gX^g (affected female), X^gY (affected male)50% or 1/2 of their sons is still expected to have G6PD. The ratio remains unchanged.

All of the following protect the skin and mucous membranes from infection except
leva [86]

The question is incomplete. Th ecomplete question is as following:

All of the following protect the skin and mucous membranes from infection EXCEPT  

A) multiple layers of cells.

B) tears.

C) saliva.

D) HCl.

E) the "ciliary escalator."

Answer: D) HCl.

Explanation:

  • The epidermis, the outer layer of the skin provides waterproofing and serves as a barrier to infection and other laers also sustain any type of injury.  
  • Tears wash out foreign bodies which enter the eye. In addition, tears contain a substance called lysozyme which has an antibacterial function and works to prevent microbial invasion and infection.  
  • Saliva protects against infection, especially via the innate immune system. This mechanism is an important first-line protection against bacterial and viral infection
  • The mucociliar escalator is within the conducting airways and is composed of mucus and cilia that transfer the mucus up and out of the lungs where it can be removed by coughing or swallowing,

Whereas HCL helps in the digestion process.

Hence, the correct option is D.
