Symbiotic Relationships :
A long term relationship between two biotic factors, where at least one benefits
Mutualism= symbiotic relationship where both organisms benefit (+,+) o Example- rhino & woodpecker (rhino gets rid of parasites and bird gets food)
Parasitism = symbiotic relationship where one benefits and the other is harmed, but not typically to the point of death (+,-) o Example- tapeworm in an animal, tick or flea on a dog (parasite benefits at the expense of the host)
Commensalism = symbiotic relationship where one benefits and the other is neither helped nor harmed (+, 0) o Example- barnacles on a scallop (barnacles get a habitat/place to attach while the scallop is not hurt or helped by their presence).
Symbiotic Relationships:
In symbiosis, two or more species live together in a close, long term association. Symbiotic relationships can be beneficial to both organisms or may benefit one organism and leave the other harmed or unaffected. Parasitism is one type of symbiotic relationship that is detrimental to, or harms, the host organism. In this relationship, one organism feeds on and usually lives in another, typically larger, organism. Mutualism is a symbiotic relationship in which both participating species benefit. A well known instance of mutualism involves ants and aphids. The ants feed on fluid the aphids secrete, and in exchange, the ants protect the aphids from insect predators. A third from of symbiosis is commensalism, a symbiotic relationship in which one species benefits and the other is neither harmed nor helped. Among the best-known examples of commensalism are the feeding and protection relationships between certain small tropical fishes and sea anemones, marine animals that have stinging tentacles.

Answer:
Explanation:
See the illustration below:
APOENZYME + COFACTOR/COENZYME = HOLOENZYME
Note: All known enzymes are proteins
Apoenzyme is the protein portion of the enzyme.
COFACTOR is the added portion to make a BIOLOGICALLY ACTIVE enzyme known as Holoenzyme.
It represents the dominance.
<span>The dominance occurs when an allele (dominant) that is expressed in an organism’s phenotype, masks the effect of the recessive allele that is also present. In this case allele for brown coat color (F) is dominant to the allele for white coat color (f). When these two alleles are together (genotype is Ff) the brown color will be expressed as a phenotype.</span>
