Answer:
Bacteria do not possess the tendency to withdraw sequences of introns from a gene, thus, if the gene for the human growth hormone were transcribed, it would translate into a non-functional protein.
When the expression of a gene takes place in eukaryotes, the budding mRNA comprising introns are removed consequently at the time of post-translational processing to produce mature mRNA. Also, the human growth hormone is produced by the pituitary gland in the form of a pre-hormone comprising a leader peptide of about 20 amino acids in length, which need to get removed post-translationally to produce a mature functional protein.
Bacteria do not possess the biochemical machinery either to effectively withdraw the leader peptide after translation or to splice out the introns. Thus, when an unchanged human growth hormone is cloned, the bacteria cannot produce the functional human growth hormone.
Answer:B
Explanation:
The last pair are sex chromosomes. Different pair is XY which is a male chromosome. Same pair is XX which is Female
"Estrogen is involved in a feedback mechanism associated with the follicular phase of menstruation.<span> In a negative feedback mechanism, estrogen released from follicles influences the pituitary gland to decrease the production of follicle stimulating hormone, also known as FSH. In a positive feedback mechanism, rising estrogen causes FSH to increase"

Answer:
B. The Red Squirrel population would increase.
Explanation:
There isn’t another animal the would eat the Red Squirrels, therefore causing the Red Squirrels to over populate.
