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>.

When dogs look at a human face, where do they focus ?​
WARRIOR [948]

Answer:

Dogs are wonderful human companions.  They are the first species that humans domesticated and they have a long history of close relationships with people.  

If you spend any time with dogs (I have two wonderful adopted dogs who shower me with affection and fur), then you see first-hand the many ways that dogs can respond to their owners.  A dog may treat a stranger with suspicion, but dances with joy when its owner returns.  Indeed, when one of our grown children returns after a long absence, the dogs respond with excitement.
