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>.

In two or more complete sentences, describe an activity you perform that has an impact on climate change? Is it positive or nega
Phoenix [80]

Answer:

Burning of woods has a negative impact on the climate.

Explanation:

Burning of woods for heating has a negative impact on our climate because it releases carbondioxide gas which is a greenhouse gas that trapped the reflected solar radiation and leads to global warming. We have to used alternative methods for heating such as electric heater instead of burning of wood which produce no pollution and can fulfill the requirement of heating so from the above discussion we can say that the activity has a negative impact on the environment.
