​

1.) When does a woman run out of eggs?

A.) your ovaries cease to make estrogen, and you will go through the menopause. At the age of 45 to 50

2.) What is the name of the lining of the uterus?

A.) Endometrium

3.) What does estrogen do to the lining of the uterus?

A.) estrogen causes further proliferation of the stromal cells of the epithelial lining of the uterus.

4.) What hormone is released due to the rising level of estrogen in the bloodstream?

A.) When the level of estrogen is sufficiently high, it produces a sudden release of LH, usually around day thirteen of the cycle.

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."    

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
