Only a few hundred of the more than 200,000 speciesof plants have been domesticated for human use. Oneexample is the almond. The domestic almond is nutritiousand harmless, but its wild precursor can cause cyanidepoisoning. The oak makes potentially nutritious seeds(acorns) that contain very bitter-tasting tannins. Ifwe could breed the tannin out of acorns, they mightbecome a delicacy. Why do you suppose we have failed todomesticate oaks?

When tomatoes are fully ripe, they develop bright red skins. William recently built a garden and decided to investigate tomato reproduction. He found that green tomatoes (not fully ripe) have an 18% chance of germinating while red tomatoes (fully ripe) have a 78% chance of germinating. Based on the data provided from the investigation, explain what characteristic(s) contributes to the probability of the tomatoes reproductive success and what factors (genetic or environmental) might impact the growth and development of the tomatoes. Answer should be based on : Claim: includes the idea that characteristic animal behaviors or specialized plant structures affect the probability of successful reproduction. Evidence: supports claim including: -behaviors and/or structures that increase the probability of reproduction -cause and effect relationship between the behavior/structure and the successful reproduction of organisms that have them -plant reproduction and the animal behaviors…

Roscroot (Sedum integrifohum) is an herbaccous plant species that is found on limestone cliffs in southeastern Minnesota and westem New York. and on rocks slopes at high elevations (3,000 m. or - 10.000 At) in Colorado. In Minnesota and New York. the plants are sprawling and have -drooping leaves, whereas in Colorado the plants are erect and hold their caves upright. a. Briefly describe a study that vou could do in order to determine if the differences in plant morphology observed in these populations of roscroot are genetically based or due to environmental factors and describe the results that would allow vou to conclude that it is heritable.
