DDT was one of the first chemicals in widespread use as a pesticide. Following World War II, it was promoted as a wonder-chemical, the simple solution to pest problems large and small. Today, nearly 40 years after DDT was banned in the U.S., we continue to live with its long-lasting effects:
Correct answer - C Pinches in.
Why? - Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. The contractile ring shrinks at the equator of the cell, PINCHING the plasma membrane or cell membrane inward
Answer:
<h2>Incomplete dominance</h2>
Explanation:
As given here;
Two pure line of four-o'clock plant, one having red flower and other having white flower, when they are crossed, they produce all pink progeny.
So, lets red as RR and white as rr
Cross between RR and rr
Here all offspring are Rr ( Pink ).
It's the result of incomplete dominance, in complete dominance the offspring is the intermediate of both the parents.
F2 generation:
As cross between Rr and Rr
progeny are: RR, Rr, Rr, rr
RR =red
Rr= pink
rr= white
So, red: pink: white = 25:50:25
Answer:
When the average kinetic energy of the molecules goes up (a rise in temperature), the average speed of the molecules increases. And lower average kinetic energy of the molecules means they have lower speed.
hope this helped !! ✨
