Answer:
It shows which consumes which. A basic food chain.
Explanation:
Wherever the arrowhead is pointed at, shows that it consumes the specie next to the nock. For example, the arrow on the left has its arrowhead directed at the butterfly. This means that the butterfly consumes the flower. The next arrowhead points at the bird, which means that this bird consumes the butterfly.
Polyallelism.
Poly means many. So, when there are more than two alleles for the same gene locus we call it of polyallelism. This makes genetic variability much bigger because there are several alleles for a possible location in a chromosome and this would make, for example, from two parents a possible combination of two out of four possible alleles if between them they had all different alleles.
The researchers start in diverse places on the research cycle. The point 1 indicates a deductive approach to research while point 2 indicates an inductive approach. The main alteration among inductive and deductive approaches to research is that whilst a deductive approach is aimed and testing theory, an inductive approach is apprehensive with the generation of new theory developing from the data.
The phospholipid bilayer is a non covalent aggregate; the lipids and the proteins molecules are held together chemical interactions such as vander waal's forces and hydrogen bond. The vander waals forces hold the hydrophobic tails together while the hydrogen bond helps to stabilize the lipid bi-layer structure.
Answer:
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
