In pea plants, there is a gene called the pod gene. This gene codes for a protein that limits the number of pea pods the plant can form. Farmers want to grow pea plants that produce more pods, so a scientist develops a chemical that binds to the pod protein and inactivates it. The scientist hypothesizes that exposing plants to the chemical will cause them to produce more pods. Describe a good experiment to test the scientist's hypothesis. Also describe...

Situation: For the first time, a scientist has successfully cloned a human being. Although the clone shares the exact DNA with the original human being, the cerebral cortex in the brain of the clone is shut down from birth, meaning that the clone will be born into a persistent vegetative state and remains so for the rest of their lifespan. The scientist plans to utilize this technology to produce a backup copy of his paying customers who want to have...
