Answer;
-Endocytosis
Explanation;
-Endocytosis includes; phagocytosis, pinocytosis, and receptor mediated: Endocytosis brings substances into the cell, plasma membrane surrounds the substances to be taken in, encloses them in a membrane-bound sac (vesicle) and brings them into the cell
-Phagocytosis: endocytosis of large solid particles (“cell eating”)
-Pinocytosis: endocytosis of extracellular fluid that contains dissolved solutes (“cell drinking”)
-Receptor-mediated: highly selective, ligands bind to specific receptor proteins on the plasma membrane and are then taken into the cell
-Exocytosis: the reverse of endocytosis: substances are removed from the cell; vesicles fuse with plasma membrane and release their contents into the extracellular fluid; important in nerve cells to release neurotransmitter and secretory cells to release cell products (ex. digestive enzymes, protein hormones).
Answer:
more Na+ diffuse into the cell than K+ diffuse out of it
Explanation:
When a nerve cell is stimulated, the electrical properties of the membrane are momentarily reversed. The inside of the membrane attains a positive charge of up to +40 millivolts, while the outside becomes negatively charged. Under these conditions the membrane is said to be depolarized.
Heterotrophic bacteria can't create their own food,but it can obtain energy from carbohydrates and other organic materials
The periderm is a multilayered tissue that is different from the epidermis which is single layered. It is made of cork cells (phellem) , phelloderm and phellogen (or cork cambium).
Cork cells are nonliving cells found covering the outside of roots and stems to provide protection and insulation to the plant.
The periderm serves to protect the plant from injury, pathogens, excessive water loss and provides insulation for the plant.
True, DNA is DNA, it matters not wether or not it belongs to a plant, you could mix a carrot with a pig (not sure why you would, but you can)
