Which object would have a larger gravitational force acting upon it
fiasKO [112]

Answer

Hi,

An object with the largest size will have a large gravitational force acting on it. Explanation

The gravitation force increases with increase in size of an object. An object that has twice as much mass will exert two times as much gravitational pull on other objects. An object with greater mass attracts the earth more strongly that the other one with smaller mass. On the earth’s space, the more massive objects will exert stronger gravitational forces.

Best wishes!

This diagram shows the menstrual cycle.
LiRa [457]

Answer:

According to the hormone diagram of the menstrual cycle, the woman is not pregnant due to the behavior of progesterone and estrogens, whose levels do not increase, in addition to the absence of human chorionic gonadotropin.

Explanation:

The graph shows the behavior of hormones during a woman's menstrual cycle in the absence of pregnancy.

During a woman's normal cycle, estrogen, luteinizing hormone (LH) and follicle stimulating hormone (FSH) tend to increase prior to ovulation, reach their peak values at ovulation, and then decline, as shown in the graph. Progesterone, on the other hand, increases after ovulation and decreases if the woman does not become pregnant.

In the case of a pregnant woman:

  • <u>Estrogens</u> continue to increase after ovulation, produced by the ovaries and placenta.
  • <u>Progesterone</u> also increases its levels, as it is a hormone produced by the ovaries and placenta.
  • <u>Hormone human chorionic gonadotropin</u> (HCG) appears and increases during pregnancy, due to the secretory activity of the placenta.

<em><u>The diagram represents the normal cycle of a woman who is not pregnant</u></em>.

How are the processes of asexual reproduction and sexual reproduction different? Select three options.
Butoxors [25]
RNA has great capability as a genetic molecule; it once had to carry on hereditary processes on its own. It now seems certain that RNA was the first molecule of heredity, so it evolved all the essential methods for storing and expressing genetic information before DNA came onto the scene.
