Answer:
To begin, in direct relation to plasma membranes, we have the fluid mosaic model, explanation for various observations related to the structure of cell membranes. In this model, there is a lipid bilayer where protein molecules are fixed. The lipid bilayer allows the membrane to achieve elasticity. This model of the cell membrane is how scientists view the functions and parts of the cell membrane. The fluid mosaic model can also serve as an explanation for the phospholipids, cholesterol, proteins, and carbohydrates that make up the membrane. Before delving into the fluid mosaic model, one must first fully understand plasma membranes and the role that they play. The plasma membrane is the membrane in all cells that protects it from the outside environment. The plasma membrane controls materials that come and go from the cell. The membrane is mainly formed of amphiphilic or dual-loving, phospholipid molecules. The hydrophilic part of these molecules is in constant contact with the fluid inside of and surrounding the cell. The phospholipid molecule is made of a three-carbon glycerol base with two fatty acid molecules attached to two of the carbons, and a phosphate-containing group attached to the third one. This arrangement results in a polar charge. The membrane surfaces that face the inside and outside of the cell are hydrophilic. In opposition, the middle of the cell membrane is hydrophobic. Therefore, phospholipids form an effective lipid bilayer cell membrane that divides fluid within the cell from the liquid outside of the cell. In conclusion, fluid mosaic is used by scientists to view the parts of the cell membrane, which has a lot of components that render it non-permeable. (phospholipids, integral protein, peripheral protein, cholesterol, glycoproteins/lipids.)

Answer:
moss
Explanation:
An ecosystem undergoing forest succession would likely start out with moss.
Answer:
1. Magnesium and oxygen atoms bond to form an ionic compound; this is evident because one forms a cation and the other an anion. When an ionic compound is formed, one atom "steals" an electron (or electrons) from another. In this case, an oxygen atom (which is pretty electronegative by the way) "steals" 2 electrons from a magnesium atom. The resulting oxygen anion and magnesium cation attract one another to form a bond (more specifically, an ionic one).
2. The oxygen atom needed two sodium atoms to bond because it needs two additional electrons to achieve a stable octet of electrons. 1 sodium atom provides 1 additional electron after it is "stolen" by oxygen, so 2 sodium atoms are needed in total to form the bond.
3. The magnesium atom needed two fluorine atoms to bond because it needs to lose two electrons to achieve a stable configuration/octet of electrons. 1 fluorine atom "steals" one electron, so 2 are needed in total.

Answer:
The new cells are the same as the previous ones, since they are the result of the mitosis process.
Explanation:
When we cut our skin, our brain sends information to millions of cells to take action and prevent this cut from putting us in danger. At that moment, the blood cells begin their work, supplying enough oxygen to stop possible bleeding and start the healing process. Then another group of cells swap out possible bacteria that may be trying to get into the wound. Last but not least, skin cells enter cell division and undergo mitosis, to generate new cells and create a new skin layer.
New cells are the same as old cells, as they are the result of mitosis. Mitosis is the process of cell division where one cell gives rise to two cells exactly the same as it.
