Two students fertilize a pair of pea plants. One plant is Rr, and the other is rr. The offspring produced by these two plants all had the dominant trait. The Punnett square showed that there was a 50 percent chance of the offspring carrying rr genes. So, the student assumes that he made an error in determining the genetic makeup of the plants. Do you think the student made an error, or is there another explanation? Explain your answer.

what's the rest of the question

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

a plastic spoon that has a temperature of 78° f is placed into a bowl of soup that has a temperature of 84° f. which of these correctly describes what will happen?

energy as heat moves from the soup to the spoon.
