Answer:

Sensitization.

Explanation:

Hypersensitive reaction may be defined as the exaggerated or hyper response of the immune system. Hypersensitive reactions can occur due to auto immunity and allergies.

Type I hypersensitive reaction is mainly mediated by IgE antibodies. The sensitization towards particular stimuli like pollen grains may exaggerate the Type I hypersensitive reaction.

Thus, the correct answer is option (1).

A man who has male pattern baldness (X^bY) marries a woman who does not carry the allele (X^BX^B). What genotypic ratios would b

JulijaS [17]

Answer:

2 $X^BX^b$ :2 $X^BY$

Explanation:

The genotypic ratio of expected of their offspring would be 2 $X^BX^b$ :2 $X^BY$ .

From the illustration, the genotype of the man with male pattern baldness is $X^bY$ while the genotype of the woman without the baldness allele is $X^BX^B$ .

Crossing the two genotypes in marriage:

$X^bY$ x $X^BX^B$

Progeny: $X^BX^b$ $X^BX^b$ $X^BY$ $X^BY$

Hence, the genotypic ratio of the offspring becomes:

2 $X^BX^b$ :2 $X^BY$

in the system labels B in figure 27-11, where does oxygen-poor blood go after leaving the heart? Why?

Komok [63]

Oxygen-poor blood goes into the lungs and through the lung capillaries after leaving the heart. It does so to be oxygenated by the lungs. The oxygen in the lungs comes from the air we breath. Once the blood is oxygenated, it goes back into the heart, to be pumped back into our bodies for distribution.
