Compare types of models. Which model would be most useful to illustrate the formation of blood cells?(1 point) Responses computer-generated model computer-generated model plastic bone plastic bone photograph of a bone photograph of a bone dissected pig dissected pig
The model that would be most useful to illustrate the formation of blood cells is a computer-generated model. This type of model can effectively represent complex biological processes and allow for dynamic visualization of blood cell formation.
Recall what you know about hypertonic, hypotonic, and isotonic solutions. What happens to the cell in a hypotonic solution?(1 point) Responses The cell and the environment have an equal amount of solute, so there is no net movement of solvent in and out of the cell. The cell and the environment have an equal amount of solute, so there is no net movement of solvent in and out of the cell. The cell has less solute that its environment, so solvent moves from inside the cell to outside the cell, causing the cell to shrink. The cell has less solute that its environment, so solvent moves from inside the cell to outside the cell, causing the cell to shrink. The cell has more solute than its environment, so solvent moves from outside the cell to inside the cell, causing the cell to swell. The cell has more solute than its environment, so solvent moves from outside the cell to inside the cell, causing the cell to swell. The cell has less solute in its environment, so the cell membrane extends around the solute and takes it out of the cell.
In a hypotonic solution, the cell has more solute than its environment, so solvent moves from outside the cell to inside the cell, causing the cell to swell.
