Answer:
<em>Auxin</em>
<em>gibberellins or gibberellic acids</em>
<em>cytokinins</em>
<em>ethylene</em>
Answer:
The correct answer will be option-D
Explanation:
Stem cells are the cells which have the ability to form different types of cells. They differentiate and specializes to perform different functions in the body and thus forms the different cells.
The differentiation and specialization are controlled at the gene level by different patterns of gene expression. The pattern of gene expression is not fully understood during development but research have shown that the gene expression is influenced by the different environmental signals and internal regulators.
Thus, option-D is the correct answer.
Answer:
C. Kinesin hydrolyzes ATP.
Explanation:
The central force-generating element that the two types of motor proteins (Kinesin and Myosin) have in common includes the site of ATP binding and the machinery necessary to translate ATP hydrolysis into an allosteric conformational change. Kinesin must use the energy derived from ATP binding and hydrolysis to force a large movement in part of the protein molecule. When kinesin forms a rigor-like tight association with the head location of the microtubule, the ATP is bound to the kinesin, and it is hydrolysis of ATP that promotes release of the motor from its track. Thus, myosins can typically drive filament sliding much more rapidly than kinesins, even though they hydrolyze ATP at comparable rates and take molecular steps of comparable length.
