You are a farmer starting an orchard and interested in breeding citrus trees. In grapefruits, big fruit (B) is dominant over small fruit (b), and silky skin (S) is dominant over rough skin (s). You cross a homozygous tree that has big fruit and silky skin, with a homozygous tree that has small fruit and rough skin. You self-cross the F1 to produce the F2.
Required:
a. What will be the phenotypic ratios in the F2?
b. If you backcross an F1 tree with the big, silky skin parent, what phenotypes and proportions would you expect in the offspring?
c. If you backcross an F1 tree with the small, rough skin parent, what phenotypes and proportions would you expect in the offspring?

Sea levels are rising due to climate change while increasing numbers of people are moving into coastal areas. to accommodate more people, there has been increased construction of beachfront resorts and condominiums. how is this impacting sea turtle numbers and biodiversity and why? a. the increased human population in coastal areas has meant that more food is available to the turtles (e. g., dropped food, waste from restaurants), which has led to an increase in the numbers and diversity of sea turtles. b. there has been very little change in the numbers and biodiversity of sea turtles because the planet is so vast that they can simply relocate to less crowded beaches. c. this has resulted in a decrease in numbers and diversity of sea turtles because it is restricting available nesting sites, and hence reproduction. d. this has resulted in an increase in numbers and diversity of sea turtles because people are around to protect them from natural predators.

Clara wrote the following hypothesis for an experiment about acidophilic bacteria. bacteria cells will stop dividing in a basic (alkaline) environment because of the high ph. which statement is the best way to restate the hypothesis so that it is more specific? growing acidophilic bacteria in some environments will cause the cells to stop dividing because of ph. if the ph of their environment is changed, acidophilic bacterial cell division will be affected. if the environment of acidophilic bacterial cells becomes alkaline, the bacteria will stop dividing. the more alkaline an environment, the less cell division will occur in bacteria.
