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:

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

The diagram represents the normal cycle of a woman who is not pregnant.

klasskru [66]

Answer:

the overlapping decreases between the thin and thick filaments.

Explanation:

When w extend our hand or arm to the full and try to lift any heavy object, we are unable to lift the object inspite of applying all our force. We struggle hard to lift the object with our fully extended arm because when we extend our arm fully it decreases the overlapping of our thin and the thick filaments of our muscles which makes it difficult to lift. In other words, the resting length of our arm is the optimal length to generate force.
