Mass does<span> not </span>affect<span> the </span>acceleration<span> due to gravity in any measurable way. The two quantities are independent of one another. Light </span>objects<span> accelerate more slowly than heavy </span>objects<span> only when forces other than gravity are also at work. When this happens, an </span>object<span> may be falling, but it is not in free fall.
Mass does matter when pointed in a downward angle, like if you have a metal toy car racing down a large peice of wood at a downward angle. If you had a plasitic car aong side it to measure which would go faster the metal car will reach the bottom quicker, gravity weighs down things :)</span>
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.
Explanation:
During the process of photosynthesis, light penetrates the cell and passes into the chloroplast. The light energy is intercepted by chlorophyll molecules on the granal stacks. Some of the light energy is converted to chemical energy. During this process, a phosphate is added to a molecule to cause the formation of ATP.
Explanation:
Halotolerant is the ability of the organism to grow at the higher concentration of salt than the required concentration for its growth.
As we know Mannitol salt is used as selective medium for isolation of pathogenic bacteria. The medium has mannitol salt, phenol red indicator, 7.5% sodium chloride. This high salt concentration inhibits the growth of most bacteria.
