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 b because the kinetic energy get hots
Answer: Groundwater can remain in subsurface storage for long periods of time.
Explanation:
The ground water is the water reservoir that gets accumulated beneath the earth crust due to the accumulation of water that seeps into the soil and rock due to the absorption by water bodies river, lakes, ponds, oceans, and rain or any kind of precipitation. The groundwater remains as a subsurface storage of water until the site of groundwater is searched and water is extracted from it for household, agricultural or industrial purposes.
Answer:
The cyclins activate the CDKs, which affect the cell cycle at three important checkpoints: Late in the G1 stage of the cell cycle, triggering the cell to move into the S phase.
