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:
The correct answer is -
Parental genotypes: AO & BO
Children genotypes: AB, AO, BO, and OO
Explanation:
In the human blood group system, more than two types of alleles are present that lead to the existence of four blood groups in the human population.
Here, A and B alleles are co-dominant while the O allele is recessive to both A and B alleles in the ABO system.
The cross depicting the genotypes of children is
IA IO
IB IAIB IBIO
IO IAIO IOIO
In this cross, we get the same result as given in the question -
One parent has A and the other has B type blood while the children have all four types of blood groups One has Type A, one has Type B, one has Type AB, and the last has Type O. It is possible only when parents are heterozygous in their genotypes and not expressing codominance.
Answer:
Cells / Cells Unit
Explanation:
The reason why cells is the basic unit of structure and function in all living things is because the cells form parts for the organism and it carries out all of the organism's processes or it's functions.
