Answer:
If an element is neutral, then it has the same amount of protons and electrons. So the element will have 11 electrons.
Explanation:
Larger cells have slower diffusion rates.
This is because the ratio of;
surface area of a cell : volume of a cell
Decreases with size, as volume increases exponentially with respect to surface area.
We might consider that;
Surface area = X²,
<em>Volume = X</em>³
As X increases, X² : X³ decreases.
So large cells have more trouble with diffusion.
A scientific theory is a broad explanation for events that is widely accepted as true. Evolution is a change in species over time. Evolution occurs by natural selection. The cell theory states that all living things are made up of cells, and living cells always come from other living cells.
Proteins, nucleic acids, and carbohydrates are grouped by common structural features found within their group. lipids can be grouped based on their high solubility in nonpolar solvents, and their preponderance of nonpolar groups.
Non-polar solvents cannot dissolve a polar compounds since no opposite charge exist, and the polar compound is not attracted. It is this becuase of absence of partial charge that also makes these molecules non-polar. Some of examples of non-polar solvents include benzene, hexane, pentane, toluene, etc.
Higher the solubility of a compound is that the larger the amount of the compound which can dissolve in a solution.
