I think the correct answer from the choices listed above is option C. The purpose of a controlled experiment is to examine whether one variable causes a change in another. A<span>n independent variable is the only factor that is allowed to be adjusted, with the dependent variable as the factor that the independent variable will affect.</span>
Answer:
3 Neurons are the specialized cells responsible for allowing all the basic body functions to take place correctly as all the necessary communication happens through them. Muscle cells or myocyte cells are specialized in making all movement possible. These cells have a cylindrical shape that allows them to contract.
Explanation:
4 Each cell must be able to perform as a part of a living organism. Cell specialization is required for cells to perform as a part of a whole living thing. Different cells do different jobs.
<span>The introduction of an unpleasant or painful stimulus, or the removal of a desirable stimulus, can be use to decrease the probability that a preceding behavior will occur in the future can be classified as punishment. This is a behavior modification which is a technique that is use to promote desirable behavior and lessen undesirable behavior.</span>
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.
