Graphite is a mineral composed of stacked sheets of carbon atoms with a hexagonal crystal structure. It is the most stable form of pure carbon under standard conditions. Graphite is very soft, has a low specific gravity, is relatively non-reactive, and has high electrical and thermal conductivity.
Answer:
Germinal disk (blastoderm) -- a small, circular, white spot (2-3 mm across) on the surface of the yolk; it is where the sperm enters the egg. The nucleus of the egg is in the blastodisc. The embryo develops from this disk, and gradually sends blood vessels into the yolk to use for nutrition as the embryo develops.
Explanation:
10 ) More erosion was taking place
11) Waves and currents are constantly beating on rock formations either on cliff faces that are between a rushing river, or the large rocks that the ocean waves crash onto. These sediments that are created by these examples of erosion are carried to new areas where, over time, they will begin to dorm new rock formations (Sedimentary rock)
12) Due to the loss of support that the groundwater acted as for the land that resided over on top of it, the ground began to collapse due to the lack of the water's support.
Here are some Ideas I came up with
1. Get a pet
Pets can be great company and if you get a trained one they shouldn't be that hard to take care of. You can also benifit since hte pet will help you get out more.
2. Start those piano lessons
Its never to late to learn something new. Plus maybe you'll have fun.
3. Join a club with fellow people that have the same issues that you do.
Being around people that can relate to your problem is a big help. Plus you might make some new friends
Hope this helps!
Schwann and Schleiden made an error about the central feature of the cells because they both agreed that cells could originate from noncellular matter. Some biologists believed that spontaneous generation could occur in the presence of air. that is life could rise from nonliving matter in the presence of air. However French scientist Louis Pastuer performed an experiment to prove that spontaneous generation of life does not occur today. Reasons why it has been concluded that cells cannot rise from noncellular matter include up to today, no known example of increase in mass of cells without cell division and cells are highly complex and no any mechanism has been suggested to be able to create simpler subunits.
