Answer: norm of reaction

Step-by-step explanation:

norm of a reaction which is the capacity of a genotype to produce different phenotypes in response to the environment. The group of phenotypic expressions under different environmental conditions. A organism can own all the genetic complements necessary to fully development. However, if there is no suitable nutricion, the development does not occur. The environment only changes the phenotypic characteristics within certain limits ruled by the genotype (norm of reaction). The genotype do not determine a phenotypes, but a amount of possible phenotypes, a norm of reaction. A certain phenotype will materialize itself depending on the interaction of a certain genotype with the environment.

soln,

here area of base = 25/4 unit ^ 2

height of the prism = 8/5 unit

so,

volume of prism = area of base x height of the prism

$= \frac{25}{4} \times \frac{8}{5}$

$= 10 \: \: {unit}^{2}$

so the volume of the prism is 10 unit^2
