I went to the beach and set up my things right next to the water. I then decided to go for a long walk and came back an hour later to find my towel soaked and my shoes missing! What happened?

The waves soaked your towel and swept you shoes away.

Explanation:

Because of the question’s context, it must be referring to natural causes. If you set up your things on the waterline, an hour is more then enough for your towel to be swept away. The towel has a lot of surface area and covers a large area, the tide didn’t sweep it into the ocean. Your shoes had a much less fortunate fate.

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.

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.
