Answer:
Colchicine inhibits the formation of microtubules by inhibiting tubulin, a protein required for microtubule synthesis. Microtubules in the form of spindle fibers during cell division pull the DNA from the center of the mother cell into the new daughter cells. If microtubules are not formed DNA will not move into new cells. Hence new cell formation will be inhibited in the metaphase stage. Thus the correct answer is option D.
Explanation:
What is the main source of downward convection<span> flow in the mantle called? The downward sliding characteristic of ridge-push is the result of what? </span>What causes<span> the </span>thermal convection that drives plate motion<span>? Is it the downward arm of convective flow in the mantle?
Here's your answer...
</span>The heat driving<span> mantle </span>convection<span> has three sources. "Primordial" </span>heat<span> (left over from the accretion and differentiation that led to the formation of Earth's core) contributes 20 to 50% of the </span>heat<span>. ... Mantle </span>convection<span> is the main mechanism by which this </span>heat<span> escapes from the interior of Earth.

In the given case, the percent of total driver under the age of 20 are (9435/92290)*100 = 10.22%.
The percent of total male drivers are = (46021/92290)*100 = 49.87%.
Here it can be observed that the female drivers are greater in number between the age group of 20 to 59, while the male drivers are more in numbers for the individuals below the age 20 and above the age 60.
Both "depends upon the binding of that substance to a specific site on the membrane protein" and "depends upon movement of proteins from one side of the membrane to the other" are correct.
The saturation effect prevents statement 2 from being true.
