Answer:
Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation). Variation may be shown in physical appearance, metabolism, fertility, mode of reproduction, behaviour, learning and mental ability, and other obvious or measurable characters.
chromosomes or by differences in the genes carried by the chromosomes. Eye colour, body form, and disease resistance are genotypic variations. Individuals with multiple sets of chromosomes are called polyploid; many common plants have two or more times the normal number of chromosomes, and new species may arise by this type of variation. A variation cannot be identified as genotypic by observation of the organism; breeding experiments must be performed under controlled environmental conditions to determine whether or not the alteration is inheritable.
Genotypic variations are caused by differences in number or structure of Environmentally caused variations may result from one factor or the combined effects of several factors, such as climate, food supply, and actions of other organisms. Phenotypic variations also include stages in an organism’s life cycle and seasonal variations in an individual. These variations do not involve any hereditary alteration and in general are not transmitted to future generations; consequently, they are not significant in the process of evolution.

Answer:
Great White Shark
Explanation:
The great white shark is top of the food chain. The fungus is the bottom of the food chain with the decomposers. The redwood tree is the Primary consumer sense it gets its needs from the sun and the nutrients from the ground. Lastly, the frog is the fourth of the food chain with the Carnivores, secondary consumers.
Answer:
Genes are important for determining function, but nutrition modifies the extent to which different genes are expressed and thereby modulates whether individuals achieve the potential determined by their genetic background. Nutrition modifies both physical and cognitive aspects of performance.
Explanation:
which means it determines (firmly decide) on how much you exercise and what you eat, for an example if you eat unhealthy all the time like alot of dessert or sweets and ssalty foods then it gives you a unhealthy genetic backround(in which each gene functions).
It should be A. It is universal among all life on Earth.
