- If you want two sister chromatids together (XYY or YY) it is nondisjunction in meiosis what?
- If you want two non sister chromatids together (XY) it is nondisjunction in meiosis what?
- granular material visible within the nucleus
- When a receptor protein in a cell membrane acts as an enzyme, the receptor protein
- the discharging of material to the outside of a cell using vesicles is called
- A difference in the concentration of a substance across a distance.
- occurs when the plasma membrane surrounds a large substance outside the cell and moves it inside the cell
- anything that carries information between cells, serving to direct or warn
- a molecule that has a glycerol backbone, two fatty acid chains, and a phosphate containing compound
- involves water moving across the plasma membrane to the side with the greater solute concentration
- the condition that results when diffusion continues until the concentrations are the same in all areas
- occurs when substances move against the concentration gradient; requires energy and the aid of carrier proteins
- a protein that transports substances across a cell membrane
- Two transport processes that allow large substances to cross the plasma membrane.
- referring to the one with a lower solute concentration causing the cell to swell - remember HYPO:HIPPO (large)
- the movement of particles from a higher concentration to a lower concentration. Passive Transport
- the phospholipid "sea" in which embedded substances float
- The pressure that water molecules exert against the cell wall IN PLANTS.
- A model that describes the structure of cell membranes. In this model, a flexible layer made of lipid molecules is interspersed with large protein molecules that act as channels through which other molecules enter and leave the cell.
- Who concluded that all cells come from previously existing cells?
