<span>In order to obtain the building blocks for larger carbohydrates, such as cellulose and starch, plants rely on photosynthesis to produce a smaller carbohydrate, glucose. During the process of photosynthesis, atmospheric carbon dioxide and water are combined in the presence of light to produce glucose and oxygen. This glucose is then polyemerized in order to create larger, more complex carbohydrates such as cellulose.</span>
Answer: It describes water molecules moving across a membrane, which allows the water molecules to pass in and out freely, but forbids the motion of other molecules.
The current taxonomic system now has eight levels in its hierarchy, from lowest to highest, they are: species, genus, family, order, class, phylum, kingdom, domain.
Action potential travel down preganglionic nerve fibre. They travel towards Vagus Nerve near the effector organ. These impulses arrive at cardiac plexus, which create action potential in postganlianic.
