Answer:
True
Explanation:
Lipids are the primary layer of the cell membrane and are classified as hydrophilic head "water loving" and a hydrophobic tails "hates water". This lipids in the cell membrane does not dissolve in water.
Answer:
Human genetic variation generally is distributed in a continuous range, with varying clusters of frequency. The significance we give our variations, the way we perceive them—in fact, whether or not we perceive them at all—is determined by our culture
Explanation:
Answer:
When the cell has 0% sucrose I expect the cell to stay the same.
Explanation:
First of all, this question should not be confused for the statement "When the "cell" has 0% sucrose, did you expect the cell to have gained water, lost water, or stay the same. In this case, the correct answer would have been; gained water.
But, in this question, we are asked what happens to the cells at 0% sucrose concentration. At 0% (no solute) concentration, there is no net movement of water or solute into or out of the cell, because the cell is isotonic to the external environment (distilled water). Osmosis, a special kind of diffusion, is the movement of water, from areas of lower solute concentration to area of higher solute concentration, or from areas of higher water concentration to areas of lower water concentration through a semi-permeable membrane. If the water moves into the cells (hypertonic cells), then the cell gains water and increases in size, but if the cell loses water (hypotonic cell), then it reduces in size
The central element for all living things is carbon, which is why you might often hear the phrase "carbon-based" lifeforms. Another term is often "organic matter"
