A Punnett square would help here.
Let's say (R) is dominant red and (r) is recessive red, aka yellow.
You start with F1 hybrid flowers that are all (Rr) - these are all <em>orange</em>. So when they reproduce, both parents are (Rr). When you create a Punnett square, you'll see that the results for the F2 generation are (RR), (rr), and (Rr) twice.
(RR) is red, (rr) is yellow, and (Rr) is orange, just like the F1 generation.
It is called peristalsis movement.
1- they can be used as domestic fuel for cooking instead of kerosene or firewood that contribute to pollution
2-they can also used to generate electricity in rural areas as these areas has not enough resources of electricity
I honestly think it is D. Impulses.
