Answer
Option C - Skeletal Muscles
Explanation
Antagonistic pairs are the muscles that are functionally opposite, if one produces flexion, then the other's primary action is an extension. Skeletal muscles work in pairs to move a bone so that the muscles can function properly. They contract the bone making nerves deliver a message to the brain. For example. Biceps and triceps. The lower arm is moved upwards when the biceps muscle contracts and the triceps muscle is relaxed and vice versa.
The definition of Epistasis in gene biology is Choice D: when the allele of one gene masks the phenotype of another gene
Definition:
When the phenotypic effect of alleles at one gene are masked by alleles of another gene.
In essence, a gene is said to be epistatic when its presence suppresses the effect of a gene at another locus.
It is important to know that Epistatic genes are often called inhibiting genes because of their effect on other genes which are described as hypostatic.
Additionally, there are six common types of epistasis gene interactions:
- Polymeric gene interaction,

The answer is true. These are all signs of communication.
Answer:
The correct answer is e it depends primarily on positive feedback.
Explanation:
The term homeostasis deals with maintenance a constant or steady physiological state in our body.Homeostasis helps to maintain the level of all bio-active compounds such as hormones,vitamins,metabolites,antibodies,minerals within their normal cellular range.
it is because disturbance or hamperence of normal cellular level of bio-active compounds cause various physiological abnormalities in our body for example increase blood glucose level results in diabetes.
The term homeostasis depends on both positive feedback(to stimulate the production of bio-active compounds) and negative feedback(to inhibit the formation of bioactive compounds) according to our body"s need.
