Phagocytes are unable to adhere to bacteria that have external capsules concealing their membrane carbohydrates. Our immune syst
ludmilkaskok [199]

Answer:

The correct answer is c) opsonins

Explanation:

Opsonization is a process in which proteins like antibodies and complement proteins called opsonins bind to the antigens and get it recognized by the phagocyted which destroys the antigen.

Especially when bacteria is having external capsule than it becomes difficult for phagocytes to attach to the capsular surface as the recognition molecule like membrane carbohydrate of antigen is concealed by capsule.

So to encounter this, antibodies like IgG and complement proteins like C3b attaches to the antigen and get it recognized and opsonized by the phagocytes like macrophages. This opsonization causes the destruction of antigen by enzymatic lysis.

In a population of tree frogs, the allele that causes yellow eyes (Y) is dominant over the allele that causes orange eyes (y). I
Alex787 [66]

Allele that causes yellow eyes (Y) is dominant over the allele that causes orange eyes (y)

Y = 85% = 0.85 and

y = 100% - 85% = 15% = 0.15

f(y) = square root of y = √y = √0.15 = 0.387

frequency of the allele that causes orange eyes = 0.387

Once we know the value of y, Y + y = 1

Putting the value of y, we get

Y = 1 – 0.387

<span>Frequency of the dominant allele that causes yellow eyes = 0.61</span>
