The molecules in ice are close together and do not have any movement, or energy at all (frozen). The molecules in water are apart from each other and do have motion and energy. The molecule in gas or vaporization, are far apart from each other, have rapid movement, and have a great amount of energy. Just think that the lighter the liquid state of matter gets, the more energy and motion it has.
Cells are composed of water, inorganic ions, and carbon-containing (organic) molecules. Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass. Consequently, the interactions between water and the other constituents of cells are of central importance in biological chemistry.
Answer:
Through simple diffusion, down the concentration gradient.
Explanation:
The phospholipids of the membrane are amphipathic with hydrophillic heads and hydrophobic tails. Other polar molecules cannot go through this hydrophobic interior. Since small uncharged lipids are non polar and hydrohobic, they are able to go through the membrane without the help of transport proteins. Therefore, the last two options can be ruled out because facilitated diffusion includes the use of a protein. Diffusion involves molecules moving down the concentration gradient so the second option can be ruled out.
Most of the cells are made of mostly Cytoplasm. It contains all the living materials in a cell except for the nucleus. This gel-like area of the cell contains the chemical needed by the cell it resembles the white part of a raw egg.
Hope this helps ^^!
A valid concern that Amelia might have is C. The regulations will be more burdensome than in other business structures.
A corporation refers to an organization that is authorized to act as a<em> single entity</em>. A <em>corporation</em> is a legal entity and is distinct from its owners.
It should be noted that under law, <em>corporations</em> can loan and borrow money, enter contracts, sue, own assets, etc. The purpose of a corporation is to make a profit.
The concern for Amelia will be the fact that a corporation is highly regulated. It's usually monitored by government agencies. There are also <em>regulations</em> that are put in place in order to protect the rights of employees. Therefore, this may be a challenge for Amelia since she may not have the freedom like that of a sole proprietor.
