Sue's bones have become brittle,
fragile, and thin. Her doctor would most likely diagnose her with osteoporosis.

the spinal vertebrae.
Answer: True. Selective media can be used to separate gram negative from gram positive bacteria.
Explanation: Selective media allow certain types of organisms to grow, and inhibit the growth of other organisms.
For example: Media containing potassium tellurite will inhibit the growth of gram negative bacteria while media supplemented with penicillin will inhibit the growth of gram positive bacteria.
Answer:
A) The aim of the experiment is to test the plant for photosynthesis.
B) Sodium hydrogen carbonate is known to increase the amount of carbon dioxide supply to the plants. Hence, it the availability of sodium hydrogen carbonate ensures that carbon dioxide is not the limiting factor for the experiment.
C) Submerged water plants are used because using these plants makes it easier to measure the rate of photosynthesis. Water and carbon dioxide become readily available to the plant which are the reactants for photosynthesis.
