Hi,
The rda is designed to be averaged over several days.
- true
(average across a number of days, because body is good at storing based on solid, reliable evidence and observations).
Answer:
independent, dependent, control
Explanation:
The independent variable is the variable that you change. For example, if we were growing plants and wanted to see if more sun made them grow higher, you would change the amount of sun that each plant is exposed to.
The dependent variable is what you measure. This <em>depends</em> on the independent variable. So, in our plant experiment, the height of the plant is the dependent variable.
Control. The control is what stays the same. So in our plant experiment, the amount of water, type of plant, type of soil, and all of these things would stay the same to insure that the results are equal.
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>.
