Hey there,
Your question states: Explain why it makes sense that the levels of estrogen and progesterone are low in the blood of a female during menstruation.I'm a guy, but I just happen know this information.The reason why the levels of estrogen and progesterone are low in the blood of a female during menstruation is to basically produce (FSH) or follicle stimulating hormone. We need to remember that menstruation is part of the menstrual cycle, which to would help a women/teen to handle/establish a well and healthy pregnancy, (if that makes sense). The average cycle would basically be i think about like 25-28 days. And one thing to remember is that when there is a <span>ripening egg,this causes estrogen levels to rise. This would be the reason why its low.
Hope this helps</span>
Answer A seems like the best choice for this question. Just think about some of the synonyms for therefore—”hence,” “consequently,” and “thus.” Because the adverb therefore often plays the role of a conjunction, it's sometimes called a conjunctive adverb.
B isn’t the correct answer to this question because you use “On the other hand” to introduce two contrasting points, facts, or ways of looking at something.
C isn’t the correct answer because we are not comparing or contrasting anything in this sentence.
D isn’t the correct answer because “Especially” is used in a formal sentence example: She can't be sure she will win, especially at this early stage of the campaign.
This is called independent assortment
D. No, rust is not alive because it does not reproduce.
