Apure-breeding short strain of pea produces plants that are 20-26 cm in height. a pure-breeding tall strain of pea produces plants that are 46-55 cm in height. when these pure-breeding strains are crossed, the f1 plants range in height from 32 to 48 cm. which of the following statements about phenotypic variance in height is true? a) the f1 variance is due only to genetic factors. b) the f1 variance is due only to environmental factors. c) the f1 variance is due to a combination of genetic and environmental factors. d) the variance in the tall parental strain is due to a combination of genetic and environmental factors.

Simulating adaptations in a species in this activity, you will discuss in detail the adaptations in a species of rain forest plants. you will build a simulation that explains the changes in the traits of the plant population over 10 years. you will also establish a scientific explanation to justify the changes in the traits of the population, * time to complete: 1-2 hours part a an organism's adaptations are specific to its native environment. an organism that lives in a coniferous forest will have different adaptations compared to an animal that lives in a tropical rain forest. the following graphs show the temperature and precipitation throughout the year for two different forests: a coniferous forest in canada, and a tropical rain forest in belize. evaluate the graphs, and then explain why plants from these two ecosystems will have different adaptations. in your answer, explain the survival challenges that plants face in these two environments.
