Two purebred snapdragon plants are crossed, as shown in the table. Generation Phenotype and Genotype
Р Red flowers (RR) X white flowers (WW)
F1 All pink flowers (RW)
Two plants from the F1 generation are crossed to produce the F2 generation,
What is the most likely distribution of the flower color trait in the F2 generation?
A 100% plants with red flowers
OB. 100% plants with pink flowers
OC 100% plants with white flowers
OD. 75% plants with pink flowers, 25% plants with red flowers

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
