<span>This is a positive feedback. These episodes make the next glacial period even more severe and long-lasting than the one prior. This is due to the reflectance of the surface of the land having a positive relationship with how much energy is absorbed: as the reflectance increases, absorption decreases, and the glacial period increases in severity.</span>
Answer;
-Skin cells do not need crystallin for their function.
-Skin cells have the crystallin gene but do not express it.
Explanation;
-The crystallin proteins are water-soluble structural proteins that occur in high concentration in the cytoplasm of eye lens fibre cells. It has also been identified in other places such as the heart, and in aggressive breast cancer tumors.
-The main function of crystallins at least in the lens of the eye is probably to increase the refractive index while not obstructing light. The skin cell does not make crystallin protein because the skin cells do not need crystallin for their function and also they have the crystallin gene but do not express it.
Answer:
Antlions experience competition when they are still larvae and looking for food or prey intake. It is called the shadow competition in where the pits are located in the upstream that can block the path of the prey thus the ones in the downstream will have less prey intake.
<span>a. what is the frequency of the dominant allele in this population?
Let say N is dominant allele and n is the recessive allele. The disease is autosomal recessive so the patient should be homozygous recessive(nn).
If the frequency of nn is 1/750, then the frequency of n would be: </span>√(1/750)= 0.0365 = 3.65%<span>
b. assuming mating occurs at random in this population, what is the probability that a couple are both carriers of this disorder?
If the frequency of n is 3.65%, the frequency of N would be:
1=n+N
1=3.65%+N
N= 96.35%
The frequency of carrier(Nn) in population would be:
Nn= 2*N*n
Nn= 2 * </span>3.65% * 96.35%<span>
Nn= 0.0703
The chance that both of the parent is carrier would be: 0.07*0.07= 0.0049= 0.49%</span>
You are right :) a hypothesis is just what you think is going to happen and a theory is where you explain everything about it(or you try to anyway)
