Answer:
The cells in a population die at a constant rate
Explanation:
Microbial death is the loss of the ability of microbes to reproduce and survive in an environment. When a given microbial population is given a treatment, the microbial cells die at a constant rate. Microbial death rate is not dependent on the specie and nor on the antimicrobial agent.
Therefore, the microbial cells in a population does not die at once but die at a constant logarithmic rate; the cells decreases exponentially as nutrients decreases and waste product increases.
For example, if 500,000 microbes are treated or in a nutrient depleted environment and 50,000 microbes is left after 1 minute, by the next minute under the same condition 5,000 microbial cells will be left and this pattern will continue, this explains exponential decrease
All the options are incorrect. The correct answer will be THE NUMBER OF HYDROGEN IONS MOVING DOWN THE PROTEIN CHANNEL.
A proton pump is found in the inner membrane of mitochondria which is also known as hydrogen ion pump. The hydrogen ion is pumped across the inner mitochondrial membrane depending on the proton gradient.
Male Birds are usually the colorful birds to attract mates while females are camouflaged to protect their eggs/hatchlings. Ground birds need to be camouflaged because they are easy prey and they have their nests on the ground.
