The control for a complementation test, which is often omitted, is the:
Degger [83]

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.

Answer:

The ten percent rule, also known as the law of ecological tithe, has to do with the effective transfer of energy that occurs at different trophic levels, corresponding to the use of one tenth of the energy from the immediate previous level.

Explanation:

The 10 percent rule was established by the english naturalist Charles Sutherland Elton, indicating that the <u>transfer of energy from one</u><u> trophic level</u><u> to another is only 10 percent</u>. This means that the level immediately above can only use one tenth of the energy produced by the level before it.

<h3>What percentage of energy a dolphin would have after it ate a fish, that ate an insect, that ate some grass?</h3>

For example, if we say that grass produces 10000 Kcal, the insect that consumes it (primary consumer) will be able to use 1000 Kcal, the fish that consumes insects 100 Kcal and the dolphin that consumes the fish only 100 Kcal.

<em>Grass      →     Insect     →    Fish      →     Dolphin</em>

<em>10000            1000             100                   10</em>

In the end the dolphin, a tertiary consumer, will only be able to produce 10 Kcal, when in the food web the producer had 10,000 Kcal.

The 10 percent rule is not entirely accurate, since the effective transfer can be less or more than 10 percent. However, in most cases, the average energy transfer is around 10%, which complies with the rule.
