I wpupd say D but im not sure
Answer:
A. Increase
B. Increase
C. Decrease
D. Remain fairly constant or change slightly
E. Increase
F. Increase
Explanation:
A. Following deep breathing of room air, the partial pressure of oxygen in plasma will increase because of higher concentrations of oxygen.
B. Following deep breathing of room air, the partial pressure of carbon dioxide in plasma will decrease because because of higher concentrations of oxygen and increase in oxygen uptake by the lungs.
C. Following deep breathing of room air, respiratory drive will decrease of saturation of blood and tissue with oxygen.
D. Following deep breathing of room air, plasma oxygen content will remain fairly constant or change just slightly because the oxygen saturation levels will have been attained.
E. Following deep breathing in and out of a small paper bag, respiratory drive will increase because of the higher levels or increase in partial pressure of carbon dioxide
F. Following deep breathing in and out of a small paper bag, plasma carbon dioxide content will increase as carbon dioxide are produced from exhalation while oxygen is not being replenished.
Let H= No Hemophilia
h= Hemophilia
Now we will create the genotypes for the parents, it says that the mother is heterozygous which means she will carry the dominant and recessive allele, which would be Hh and it says the father is normal which would mean that he would be No Hemophilia dominant, so it would be HH
Cross the 2 created genotypes: Hh x HH
Now create your Punnett square using the 2 created genotypes above
H h
H HH Hh
H HH Hh
Looking at the Punnett square above, it appears that there’s a 2:2 ratio or a 50% chance of having Hemophilia and not having Hemophilia
So for a female child: 1/2 x 1/2= 1/4 of having a female with Hemophilia
The first one represents the female child having Hemophilia or not, that one can be obtained by simplifying the 2:2 ratio to a 1:1 ratio and the other one represents the chances of their child being a female. I assume that the steps above would be repeated again for the male child.
I hope that helps!
Answer:
C) They should send signaling molecules across a small extracellular space.
Explanation:
To send a message to nearby cells, signal molecules only need to cross a small amount of space. Bloodstream (choice A) is used for long-distance communication, choice D is too vague, and choice B is used only for cells that are directly touching each other.
