What is the purpose of an antibody? Group of answer choices to stick to an antigen, alerting your body of the presence of a fore
Alexandra [31]

Answer: Antibodies are proteins that are found in the body on the surface of red blood cells and in the blood plasma ,they are very sensitive to foreign bodies and bad viruses and bacteria,when they notice the presence of anything that poses harm or a threat to the body system,they track it down and fight/destroy it.

Antibodies also play crucial role in hemostasis(stoppage of bleeding) in the sense that when the body is wounded or when someone gets a cut antibodies that are found in the plasma and some substances found in the platelets are released to play a role in sending signal to the blood clotting factors in the blood to be released to arrest the bleeding and prevent the person from bleeding out their entire blood.

Alkaptoneuria is a recessive genetic disorder found among North American populations at a frequency of about 1 in 500,000 births
Dafna11 [192]

Answer:

The correct answer is - 1/41,493

Explanation:

Let assume the frequency of the two possible same allele genotype (dominant and recessive) in an inbred population is p and q. Then the frequency of heterozygotes (H) is denoted as:

2pq + 2pqF.  ( where F is the inbreeding coefficient).

The frequency of the two different hoozygotes in inbred population can be calculated as:

p2 + pqF and q2 + pqF. (Where p and q are the allele frequency of the dominant and recessive phenotype.

Given: Frequency of Alkaptonuria (q 2) = 1:500, 000

=> q = 1/707

p = 706/707 ( Approx values)

solution:

Inbreeding coefficient (F) = 1/64

Therefore,

Frequency of Alkaptonuria in second cousins= q 2 + pqF

= 1/500, 000 + (706/707 x 1/707) x (1/64)

= 1/500, 000 + 1/45, 248

= 1/41,493 (approx)

At ________, the female central nervous system (cns) is typically more advanced than the male cns.
Ilya [14]
The correct answer is birth.

At birth, females infants on an average appear to have a more developed central nervous systems compared to males. This is apparent because female infants shower higher levels of responsiveness to stimuli such as sounds, touch and faces. Additionally, female infants typically acquire linguistic abilities and vocalize earlier than male infants.
