b. impact

Waves cause erosion through the processes of impact and abrasion. Erosion is a process of removal of surface material from the surface of soils and rocks by agents like water and wind. The eroded materials get transported and deposited to other places. Erosion caused by waves is a water erosion.It is accomplished by impact created by hydraulic pressure exerted by waves to c on the surface of rocks and soils coming in contact of wave takes out larger debris deposits. Abrasion causes grinding, crushing or rubbing of rocks and soil lumps which are converted into small particles of debris taken away by water.  

answer: the blood-brain barrier is a layer of specialized membranes and cell processes designed to keep undesirable substances from passing from the bloodstream into the precious tissues of the brain. while the blood-brain barrier does keep most bad things out of the central nervous system, it is not impermeable.

explanation:

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.
