These first trees had a huge importance for the other plants and for the animals, and this was because:
- they managed to change the structure of the atmosphere by consuming, using, and storing carbon dioxide, and releasing oxygen, which made the atmosphere much more suitable for life.
- they managed to influence the climate, by making it more moist, and also making the ground bellow them cooler.
- they were producing large amounts of biomass, which made the soil types much richer in nutrients, which in turn enabled more and more plants to grow.
- they were a food source of the animals.

Answer:
Explanation:
Purple flowers (P are dominant to white (p), and long pollen (L) is dominant to short pollen (l).
A true breeding variety of peas with purple flowers and short pollen is crossed to a true breeding variety with white flowers and long pollen.
Parent genotype PPll x ppLL
F1 genotype will be PpLl
self crossing of F1 PpLl x PpLl
b. What proportion of the F2 will have purple flowers with long pollen?
Pp x Pp = 3/4 purple flowers, 1/4 white flowers
Ll x Ll = 3/4 long pollen, 1/4 short pollen
Thus answer is 3/4 x 3/4 = 9/16 purple flowers with long pollen
c. What proportion will have white flowers and short pollen?
thus, answer is 1/4 white flowers x 1/4 short pollen = 1/16.
