<h2><u>DEFINITIONS</u></h2><h2>_____________________________________</h2><h3><u>VOLUNTARY MUSCLES:</u></h3>
Voluntary muscles are those muscles which work under our conscious control and can be controlled at will also we can choose choose them when to use and when not to use. These are simply SKELETAL MUSCLES attached to the bone, so all the movements of hand and legs and whatever u do are because of voluntary muscles.
<h3><u>__________________________________________________</u></h3><h3><u>INVOLUNTARY MUSCLES:</u></h3>
the muscles in the human body that do not work under our will and we cant control them. They are mainly controlled by the autonomic nervous system in the body. So, involuntary muscles include all the muscles whose activity which is not controlled by our NERVES. They are also called SMOOTH MUSCLES since they are present as the visceral layer over the organs.
<h2>_____________________________________</h2><h2>DIFFERENCES</h2>
1) VOLUNTARY MUSCLES are under our control but INVOLUNTARY MUSCLES are not under our control
2) VOLUNTARY MUSCLES are also known as skeletal muscles but INVOLUNTARY MUSCLES are also known as smooth muscles
3) VOLUNTARY MUSCLES are attached to the bones in the body, but INVOLUNTARY MUSCLES are attached to the soft hollow internal organs.
4) VOLUNTARY MUSCLES are controlled by the somatic nervous system. INVOLUNTARY MUSCLES are controlled by the autonomic nervous system.
5) VOLUNTARY MSUCLES require more energy. INVOLUNTARY MUSCLES require less energy.

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>.
The primary products of the light independent reactions (after one turn of the cycle) are:
a) two G3P molecules
b) three ADP
c) two NADP+
However ADP and NADP+ are not really "products". They are regenerated and later used again in the Light-dependent reactions. Each G3P molecule is composed of three carbons.
For the Calvin cycle (Light independent cycle) to continue, 5 out of the 6 carbons provided by the two G3P molecules are used to regenerate ribulose 1, 5 phosphate. Therefore there remains only one carbon for the next turn of the cycle.
One molecule of glucose requires 6 turns of the cycle. Any extra G3P is used to make starch, sucrose and cellulose.
True. such as with pesticides, they are used to reduce harmful insects to crops but they often re harmful to the health of people consuming those crops
