Answer:

The ________________ in males and the _____________________ in females are permanently blocked when an individual undergoes a sterilization procedure.

a. testes; ovaries

b. testes; fallopian tubes

c. vas deferens; ovaries

d. vas deferens; fallopian tubes

Explanation:

Answer 2
Answer:

I believe the answer would be B. This would be because the Fallopian tubes I think are tied which then would help so the sperm cannot go up to the ovaries. We know that it is A or B because the first answer being tested is correct.

The exosphere is the layer of the atmosphere

Answers

Yes you're correct. It is the outermost part of the atmosphere, artificial satellites are in that layer.

Answer:

where gas molecules can be exchanged between Earth's atmosphere and outer space.

Explanation:

The exosphere is the outermost layer of earths atmosphere. The exosphere goes from about 600 km to over 10,000 km above earth's surface. The exosphere is basically the transitional area between the atmosphere and space, so gas molecules end up getting exchanged.

A company estimates its total profit (profit = total revenue minus total cost) as P(x) = 2x5 − 3x4 − 5x2 − 2, where P is in thousands of dollars and x is the number of years elapsed since the company was founded.Solve for the number of times the total profit become exactly zero. Hint: Use Descartes's rule of signs.

Answers

   Using the Descartes` rule of signs, we have to recognize how many times the signs change from positive to negative, or from negative to positive from one term to the next. There is only 1 change of signs: from +2 x5  to -3 x4. So we have only 1 real zero.
   Answer: There is only one time that the total profit become exactly zero.

Which of the following is NOT a phase in the menstrual cycle?A. ovulation
B. luteal
C. gastrulation
D. follicular

Answers

Answer:

The asnwer is C. Gastrulation.

Explanation:

Gastrulation is one of the stages of early embryonic development through which the trilaminar germinative disk is formed, which is a structure with three differentiated embryonic layers that will give rise to all the organs and tissues of the embryo. Gastrulation occurs just after embryo segmentation and implantation, that is, when the embryo has already been divided into many cells, it has become a blastocyst and has managed to nest in the endometrium, beginning pregnancy.

Knowing this, it can be concluded that it is not related to the menstrual cycle.

I believe the correct answer is gastrulation.

Explanation:

The menstrual cycle is divided into the follicular phase, the menstrual phase, ovulation phase and the luteal phase. The Ovulation phase is a phase between the menstrual cycle just before menstruation starts. Gastrulation on the other hand is a phase in embryogenesis after fertilization has occurred.

Further Explanation:

1. Ovulation phase:

This is a phase in between the menstrual cycle and is triggered by a hormone produced by the anterior pituitary gland and is called the Luteinizing hormone. The phase is when the egg has matured from the graafian follicle after it bursts. This egg will travel into the fallopian tube by the help of special structures called fimbriae hoping to be fertilized. If fertilized, the egg will attach to the uterus. If not, it is removed as menstrual blood during menstruation. In this stage, the basal body temperature of the lady increases and she will have more "feelings" for sexual intercourse.

2. Luteal phase:

It is triggered by the hormone Luteinizing Hormone (LH) that is released by the anterior pituitary gland. After the graafian follicle releases the ovum, it (graafian follicle) matures into the corpus luteum that produces copious amounts of the hormones progesterone and estrogen to prepare the uterus for implantation by thickening it and making the mucus of the cervix more thinner to allow passage of sperms. If the lady does not become pregnant, the corpus luteum will die and the uterine wall sheds in the menstrual phase.

3. Follicular phase:

This is the first phase and it starts on the first day the lady sees her period. It starts due to the anterior pituitary gland secreting the hormone follicle stimulating hormone (FSH) .The hormone will stimulate formation of ovarian follicles in the ovaries and only one matures and produces estrogen to inhibit all the other eggs from maturing and also thickening the uterus. It lasts for 14 days. The ovarian follicle matures into the graafian follicle that enters the ovulatory phase.

4. Gastrulation:

This is totally unrelated to the menstrual cycle and it is found in embryology after the egg has been fertilized during the menstrual cycle and matures into an embryo. In this stage of embryogenesis, there is formation of the gut of a developing embryo
