Answer:
Because that's just how it works.
Someone can eat a steady diet of steak and potatoes but they don't turn into steak and potatoes.
When we eat, we consume the meat and energy of the animal. We don't consume some mystical part of them that gives us their qualities.
For example:
You can eat deer meat and not get as quick as a deer, or lion meat and not get the courage of a lion.
We can apply this to the "You are what you eat" phrase people like to use.
Just because you eat a lot of donuts, for example, doesn't mean you'll turn into a donut, or get any donut like qualities (Except maybe stickiness).
Foxes eat rabbits to be healthy, and <em>alive, </em>not to eat plants and hop around and 50 thousand kids
I hope this wasn't too sarcastic-
Rereading it, it kinda came off like that-
Hope this helps though?

Answer:
Mitochondria and chloroplasts
Explanation:
These two organelles support the theory in that both have 70S ribosomes, the presence of a circular DNA within, and similar size. They can undergo division within the eukaryotic cyptoplasm. Both of these organelles are surrounded by a double membrane, which in the case of chloroplast is known to originate from ancient bacteria that lost its peptidoglycan component. Mitochondria and chloroplast both evolved from ancient free living bacteria that entered into larger cells, which in the case of mitochondria is known to be archaea and in the case of chloroplast is a eukaryotic cell. With this, these cells became dependent on it in a manner that it could not exist without it.

Answer:
A woman is born with all of her eggs, which are stored in her ovaries. The ovaries also make the hormones estrogen and progesterone, which control her period (menstruation) and the release of eggs (ovulation). Menopause happens when the ovaries no longer release an egg every month and menstruation stops.
