A) The answer is 0.1/year.
The reproductive rate for the population can be expressed as:
(number of births - number of deaths)/number of individuals = (55-5)/500 = 50/500 = 0.1
b) The answer is exponential growth.
The exponential type of population growth occurs when resources are unlimited. When there are no limiting factors, population exhibits exponential growth. If every year population has mentioned reproductive rate, that means it is not limited by any factor (food, space, etc.). Thus, it must be exponential growth.<span> </span>

Answer:
There are two ways plants can achieve this. First, they can minimize the resistance to diffusion of CO2 through the stomata (i.e., have lots of large, open stomata). Second, they can maximize the biochemical rate of fixation (i.e., have high concentrations of photosynthetic enzymes).
Maintaining acidity- <span>In case the pH in the environment drops a lot (becomes very acidic), there is a flux of H ions from the cell's cytoplasm into the cell's vacuole thereby increasing acidity to required level and thus maintaining the </span><span>specific pH </span><span>in the cells internal environment as well.
Turgidity- </span><span>Vacuoles regulate the turgidity by regulating the amount of water inside the cell. </span>
cell has excessive water:<span> vacuole absorbs the water and then diffuses it out of the cell.</span>
cell lacks water<span>: water from the vacuole gets passed back into the cell thereby maintaining turgidity.
