Evidence for evolution is provided by homologous structures. These are structures shared by related organisms that were inherited from a common ancestor. Other evidence for evolution is provided by analogous structures.
In some reactions, a single-reactant substrate is broken down into multiple products.
No organism is always the first step, except in a wide sense, plants. In the water, plankton is found in first but whereas on land, plants or seeds are eaten first.

Answer:
b. cis test
Explanation:
A test that is used to determine if the mutation associated with a given phenotype is due to mutations in two different genes or due to different alleles of the same gene is called a complementation test.
A complementation test is also called as a cis-trans test.
If the mutations in a complementation test are located on the same position then the genes are termed as being on the cis position otherwise on the trans-position.
A cis test, that is if the genes are located on the same position serves as a control for the complementation test.
