Why did the leaves rise? Will the leaf discs float faster or slower if the rate of photosynthesis is decreased? (5 points)

Leave rise and floating depends on the production of oxygen.

Explanation:

The leaves rises due to consumption of oxygen which is produced during photosynthesis. Floating of leave occurs due to production of oxygen in the process of photosynthesis. The leaf discs float faster if the rate of photosynthesis is increases because oxygen production is also increases while the leaf discs float will be slower if the rate of photosynthesis is decreased due to low production of oxygen.

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.
