I believe that renewable energy may be the answer because D is absolutely not the answer and A would not help us. That's leaves us with B and C and B seems like it's a better choice than C.
A
Planting the same crop over and over again depletes the nutrients of the soil and it also allows any pests to get used to the soil. That’s why many people practice crop rotation.
Answer:
C A single genotype produces a range of phenotypes that differ in the degree or magnitude of expression of the particular trait specified by the gene.
Explanation:
Variable expressivity refers to the range of signs and symptoms that can occur in different people with the same genetic condition.
For example, the features of Marfan syndrome vary widely— some people have only mild symptoms (such as being tall and thin with long, slender fingers), while others also experience life-threatening complications involving the heart and blood vessels. Although the features are highly variable, most people with this disorder have a mutation in the same gene (FBN1).
The right answer is 3. Spruce.
Sexual reproduction has the advantage of producing genetic diversity in the offspring (as we see it for example in humans) due to the crossing of two gametes of two different individuals as well as the genetic recombination that occur before fertilization.
Of the four propoitions, only one reproduces sexually, and that is the spruce.
The spruce is part of the genus Picea which includes conifers comprising about fifty species.
