Answer:
A signal is sent from a nerve cell to a muscle cell
Explanation:
I just took this test and this was the correct answer.
Option B would be correct. Osmosis is the movement of water molecules from higher to lower concentration, while Diffusion is the movement of higher to lower particle concentration.

Answer:
Ribosome
Explanation:prokaryotes have ribosome.
Explanation:
The plants would not retain their shapes.
Carbohydrates molecules that supply energy and provide support consist mainly of sugars or starches in long chains and rings to form monosaccharide monomers. Inclusive of monosaccharides, disaccharides and polysaccharides (which describes the type of bonding and the degree of complexity of the polymers), their basic makeup comprises C, H, O -with many polar OH groups.
Many long chain polysaccharides are made up of glucose joined by regular 1-4 glycosidic bonds used as energy storage (produced through phtosynthesis) and used for ATP synthesis via respiration, ethyl alcohol fermentation and lactic acid fermentation. Plants are mostly comprised of structural units cellulose and lignin. However, cellulose is their main structural polysaccharide, found within cell walls.
It is made up of special β, 1-4 glycosidic bonds, which give structural polysaccharides their rigid, strong structure; cellulose is not water-soluble and is highly stable. However, if these alternating bonds aren't present, the plants would lose their main structural support, which allows larger plants, and trees to grow upwards towards sunlight despite their mass. When arranged in α 1-4 glycosidic bonds these molecules are water-soluble; water would be able to flow readily out of the plant tissue. Thus the plant cells and tissue, would not retain their shapes and may be limited in their potential height without structural support.

If left untreated, excessiveerosion can lead to serious problems, such aswater sedimentation and ecosystem damage.Wind: Wind erodes the surface of a barren landmass in arid climates. Wind circulates and pushes particulates across wide bodies ofwater; a process known as deflation, which eventually leads toerosion.
