question 8 (bonus) (1 point)
select all of the ways that materials can pass into and out of a cell. select all that apply.
exocytosis
phagocytosis
pinocytosis
facilitated diffusion
active transport
osmosis
diffusion

Explanation:

Gram - Stain differentiates bacteria into Gram - positive and Gram - negative based on cell - wall differences. Exocytosis is the process of expelling materials out of the cell. Phagocytosis is the engulfing of large particles by the cell. Pinocytosis is the uptake of liquid and dissolved substances. Facilitated diffusion is the movement of molecules across the membrane with the help of transport proteins. Active transport moves molecules against the concentration gradient using energy. Osmosis is the diffusion of water across a semi - permeable membrane. Diffusion is the movement of molecules from an area of high concentration to low concentration.

Answer:

1. A. Gram Stain
2. exocytosis, phagocytosis, pinocytosis, facilitated diffusion, active transport, osmosis, diffusion
