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
Answer:
Runoff is one of the ways land water finds its way back to the ocean, so it can join the water cycle again.
Usually, all the water that falls to the land gets soaked in the soil. However, during long rainy periods, or in the spring, when snow and ice glaciers start melting, soil gets oversaturated with water, so this excess water start flowing on the earth's surface. Gravity directs this water from higher to lower areas, where it will flow into some valley river. This river will take the runoff water to another river, then to the sea or the ocean.
Now this water can evaporate and start the water cycle once more.
The correct answer would be A. seal as paramecium, bacterium, and amoeba are all single-celled organisms. Thus, they cannot be an organism with tissues.
Answer: Diatoms.
Explanation:
Diatoms are single celled group of algae that are found in aquatic habitat both freshwater and marine habitat. The are the most important primary produce in the marine habitat. They are photosynthetic I .e they have chlorophyll which help them to trap light energy from sunlight and uses carbon dioxide and water to produce food. They produce food with the process of photosynthesis.
