Which statement describes a reason why stem cell research is important? a. it allows scientists to mix the genes of different organisms to produce desired traits. b. it allows scientists to put healthy genes in cancer cells. c. it investigates the use of undifferentiated cells to cure disease. d. all of the above

C. It investigates the use of undifferentiated cells to cure disease.

Explanation:

Stem cells are like cells that can convert into any type of cells, this is very helpful because scientist can learn how to turn them into the desired cells that they need to cure a certain disease, for example if the liver is compromised or damaged, they can insert stem cells that will turn into liver cells that can help regenerate the liver, or the pancreas for diabetic people. Stem cell research has lots of applications on the branch of restoration fo the human body.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.

hope i'm right
