Answer is A. A Hox gene
Hox genes are a series of genes that controls the differentiation of cells and tissues in an embryo by turn on and off other genes. If Hox genes express incorrectly, a major changes in the morphology of the individual can be seen.
Let’s understand this with an example: The Ultrabithorax, a Hox gene determines the Third thoracic segment in <em>Drosophila melanogaster</em>. Third thoracic segment displays a pair of legs and a pair of reduced wings used for balancing. In the mutant<em> Drosophila</em> the functional Ultrabithorax protein is absent. Due to this mutation, the third thoracic segment now expresses the same structures found on the second thoracic segment, which contains a pair of legs and a pair of wings which are fully developed .
The answer is <span>hygrometer, will.
</span><span>Your <u>hygrometer</u> indicates that the relative humidity is very high. Rain probably <u>will</u> occur.
Hygrometer is an instrument used for measuring the relative humidity in the atmosphere. If the relative humidity is very high, then it rain will probably occur and vice versa.
Anemometer is an instrument used for measuring wind speed, thus it cannot be the right answer.</span>
