Codominance.
Codominance occurs when, for example, a Dominant Blue color gene for a leaf crosses with a Dominant White color gene for a leaf. The genotype would be BW. This would result in, for example, a blue and white spotted leaf color. INCOMPLETE dominance occurs when both dominant alleles blend together, resulting in, eg, a pale blue color resulting from the blue and white colors mixing.
They often respond to Quorum sensing which is determined by the cell density. Bacteria cells secrete molecules that can be detected by other bacteria, Quorum sensing allows bacteria to sense the concentration of these signalling molecules to monitor the local density of cells. It used by bacteria to coordinate certain behaviors , such as the production of biofilms.
The generally widely accepted first step of the scientific method is to ask a question.
This is where you think of a question which you want to do an experiment on, and then later on conduct an experiment to answer that question.
The answer would be respiratory because that system is used to breath oxygen and exhale carbon
Their are both different substances
