Which statements describe why organisms are classified? Check all that apply.
1. Classification shows how closely related organisms are to each other.
2. Classification makes organisms easier to study.
3. Classification allows for better identification of new organisms.
The grouping system makes it easier for scientists to study certain groups of organisms.
Option C 100mv because the membrane goes from -70 mV to +30 mV. Thus, during the action potential, the inside of the cell becomes more positive than the outside of the cell.
Answer:
Comparing DNA
Explanation:
Darwin could compare only the anatomy and embryos of living things. Today, scientists can compare their DNA. Similar DNA sequences are the strongest evidence for evolution from a common ancestor.

Answer:
1) Diffusion is net movement of anything (e.g., atom, ions, molecules) from a region of higher concentration to a region of lower concentration.
2)
Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides
3) One big difference between osmosis and diffusion is that both solvent and solute particles are free to move in diffusion, but in osmosis, only the solvent molecules (water molecules) cross the membrane.
4) Molecules tend to move from areas of higher concentration to areas of lower concentration.
I'm sorry, but I don't know how to do part #2. I think it's a lab.
