In April, a population of frogs in a local ravine had a population of 42, which was increased in May by 263 tadpoles.  Pesticide runoff killed 26 tadpoles, and predators consumed 8 frogs.  In July construction workers began clearing the ravine and ran over 12 frogs.  Calculate the population growth rate of the frogs in the ravine from April to August. 

Two pea plants with yellow peas are crossed. most of their offspring have yellow peas, but about 25 percent of the offspring have green peas. for pea color, yellow is the dominant trait and green is the recessive trait. what does this tell you about the two parent plants? a. the parent plants have only dominant alleles for pea color. b. the parent plants are heterozygous for pea color. c. pea color follows an incomplete dominance pattern of inheritance. d. the parent plants are homozygous for pea color.
