Endocytosis moves materials into a cell.
Active transport uses carrier proteins. (not entirely sure about this one... check it out to be sure)
Molecules move from an area of high concentration to an area of low concentration by passive transport.
Answer:
lowering the activation energy needed for the reaction to start
Answer:
A
Explanation:
Conduction is the exchange of energy as warmth or power starting with one iota then onto the next inside an article by direct contact. Conduction happens in solids, fluids, and gases. Nonetheless, solids move energy most proficiently since the atoms in solids are most firmly stuffed, and the particles are nearer together, as displayed in this figure. For fluids and gases, the thickness of the particles are by and large lower than those of solids and the particles are farther separated, so the energy move is less productive.
Answer:
Explanation:
1- closely packed osteons or haversian systems, used to provide strength and protection to bones.
2- Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow. provides balance to the dense and heavy compact bone by making bones lighter so that muscles can move them more easily.
