Solve the problem.Mendel found no dominance in snapdragons with respect to red and white flower color. When pure red (RR) and pure white (rr) parents are crossed, the resulting Rr combination (one of each gene) produces second generation offspring with pink flowers. Suppose one of these second generation pinks is crossed with a pure red. What is the probability that the resulting snapdragon will have white flowers?
A. 0.25 B. 0.75 C. 0.5 D. 0
Solve the problem.Suppose there are two low-frequency sound waves with similar frequencies. Let 
and 
model the two tones where t is time measured in seconds. Write the sum 
as a product of two trigonometric functions, and determine the frequency of the beats.
A. no beats 0.006 cos (83?t) cos (83?t) B. no beats 0.006 cos (41.5?t) cos (41.5?t) C. 1.5 beats per second 0.006 cos (41.5?t) cos(1.5?t) D. 3 beats per second 0.006 cos (83?t) cos (3?t)
