<h2>
Lipids
</h2>
<u>
Explanation:
</u>
Lipids are the macro-molecules used to store energy in our body. They have the ability to store energy more efficiently and are called long-term energy storage.
They can store twice as much energy as other molecules. They contain nine Kcal of energy per gram a compared to proteins and carbohydrates which only produce four kcal per gram. They are present in our body in the form of fat and are insoluble in water.
If i remember correctly asexual reproduction came first because without asexual reproduction the cells would not have been able to produce other cells so what few cells there were reproduced asexually and then it evolved onto sexual reproduction later in development
The human digestion starts in the small intestine gets the
most of the nutrients in your food, and your circulatory system passes them on
to other parts of your body to store or use.
When food enters the small intestine, villi along the intestine wall
along with enzymes help break down the food, and takes a long journey. The
stomach is right above the small intestine, and the small intestine is all
wrapped around, and isn't that thick. Nutrients from the food are released to
the whole body as energy. The small intestine brings the food to the large
intestine, which is five feet long and is near your pelvis, or hips. The large
intestine connects to the rectum, and then to the anus. In the large intestine,
all the water is absorbed as well as salt.
<span>In humans, oogenesis
in comparison to spermatogenesis is different in that the temperature they have.
Female puberty typically occurs much later than the age of male puberty oocyte
production works best at cooler temperatures than those that support
spermatogenesis oogenesis continues throughout life, but spermatogenesis
typically ends.</span>
I don't know if this helps or not but you would want to know the age of the rock (absolute dating) and from there you will be able to know the age of the fossil and what caused it to die.
