confirmation bias?
i think that may be correct but i'm not 100% positive i hope it helps a little. Good Luck
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.
Gene transfer via transduction could be beneficial if the donor has a new gene that could produce a useful protein. This protein could be an enzyme with various effect like
1 digesting food(fermentation),
2 digesting drug(drug resistance) or
3 toxin that could kill the nearby cells(to decrease food competition).
Answer:
The correct answer is D) Infundibulum
Explanation:
The Infundibulum, also regarded as the Pituitary Stalk is an area of the brain that appears like a v-shaped stem which connects the hypothalamus and the posterior pituitary gland.
It functions as a medium by which hormones are conveyed from the hypothalamus into the pituitary gland, and on to the veins.
