Answer: a. Genetic recombination (crossing over)
b. Can also be explained in terms of crossing over
c. Non disjunction of homologous chromosomes in meiosis 1
Explanation:
The process that allows for the transfer of both the paternal and maternal materials to is the crossing over process that takes at meiosis 1 changing them to secondary spermatocytes. While they are still primary spermatocytes, they are still diploid cells having both the maternal and paternal chromosomes. But since the spermatozoon is an haploid cell, it is able to retail some of both parents chromosome by the crossing over event which takes place between homologous paternal and maternal chromosomes allowing them to exchange materials. Thus the chromosomal contents of the primary spermatocyte differs from that of the spermatozoon.
C. This can occur as a result of the one of the homologous chromosome pair refusing to separate at meiosis 1 with one gamete containing 4 chromosomes/8 sister chromatids and the second having 2 chromosomes/4 sister chromatids.
The complete question is attached to the answer.
Answer:
The correct hypothesis would be - the food (proteins) are not completely broken down in the intestine due to intestinal Protease production is lower than normal in Claire.
Explanation:
According to the image, we can find that the normal intestine fluid has the same pH as the pH of claire's Intestine fluid which is suitable for the breaking down of the food or protein in particular. It is also found that there is some amount of protein digested which suggests that there is no mutation in the active site.
According to the graph, claire is able to break down or digest the food completely if 1mg proteases enzyme is used so it proves the enzyme is produced less than normal. On the basis of this information, the correct hypothesis would be -
"The food (proteins) are not completely broken down in the intestine due to intestinal Protease production is lower than normal in Claire."

Explanation:
Answer:
B. Information that is presented as scientific but has not been gathered through reliable scientific methods.
Explanation:
Pseudocience is defined as a collection of beliefs or information that claims to be scientific as it is supposedly gathered by a scientific method, but in reality, is not based on a reliable scientific method.
Although Letter A is similar, pseudoscience does not provide real "evidence," as it is based only on personal beliefs, which is also a non-reliable data. Letter C is not correct as this information is not collected through the scientific method, and Letter D is not sufficient, as pseudoscientists usually mention the fact that their beliefs or information are based on scientific facts.
As pseudoscience is falsely regarded or presented as scientific, the correct answer is Letter B.
Hey there :)
It is very important because the genes are the blueprints. RNA molecules use these directions to direct the production of proteins. This is to help to determine characteristics of an individual organism.
