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>.

Answer:
Primitive Earth where life emerged was subjected to extreme conditions
Explanation:
The origin of life is still an issue of intense debate today, although most researchers believe that life emerged from primitive organisms generated by the synthesis of organic compounds in early Earth. In line with this theory, it has been shown that membrane-forming compounds can be formed in extreme conditions (i.e., UV rays, extreme temperature, etc). It is believed that such conditions recreated in a laboratory were similar to the early Earth about 3,900 million years ago, thereby supporting the idea of the 'primordial soup theory' proposed by John Burdon Sanderson Haldane in 1929.
The correct answer is d. spinal cord.
Spinal cord is a bundle of neurons which starts from the brain and runs down the entire length of the back of the body. The spinal cord acts as a main means to transmit the messages between the brain and the body.
Sensory or efferent neurons carry the information from the perimeter of the body and pass to the central nervous system whereas the motor or efferent neurons act as a communication channel and carry the information from the nervous system to various glands and muscles.
