Aplant has been removed from its natural environment and placed into a body of water that contains a higher concentration of salt than the inside of each plant cell. the plant promptly wilts. this situation is most similar to which event? a) seaweed put into fresh water b) a land plant put into tap water c) a freshwater plant put into sea water d) a freshwater plant put into distilled water

C) a freshwater plant put into sea water

Explanation:

According to the given situation when the plant is removed from it's natural environment and placed into a body of water that contains a higher concentration of salt. The new medium will act as a hypertonic solution ( concentration of solute is more outside than inside the cell) this will lead to the loss of water from the plant cells and diffusion of salt ions inside the plant cells.  This leads to the wilting of the plant.

The condition that mimics the given situation is C)a freshwater plant put into sea water. The sea water will become a hypertonic solution for the plant, as a result of which the water inside the plant cell will come out and salt will diffuse in. The plant may not survive under such conditions.  

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.

i'd say that the moon rock is about 2.2 billion years old.
