The pea plant (pisum sativum) is a good choice for studying heredity because it

Is easy to control which plants mate with each other.

Mendel experimented a lot with pea plants and developed theories on genetics that were really useful for today's biology. He chose pea plants because they were common and good choice for hybridization experiments and also would be easy to control which plants mate with each other.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
