Answer:
The population (of the bacteria) will reduce
Explanation:
This question appear a little confusing because of the structure of the second sentence. However, it appears to describe how an antibiotic works. Antibiotics work against bacteria by either making the environment toxic for the bacteria (which kills it) or inhibiting the growth/reproduction of the bacteria. Both patterns will eventually lead a sharp reduction in the population of the bacteria. Even if what the antibiotic does is to inhibit the reproduction of the bacteria, this act provides the body with an opportunity to fight the "unreproductive" remnants of bacteria thereby leading to the reduction of population of the bacteria.
The answer is A. It kills microbes and then removes them.
Answer:
A. Phytoplankton
Explanation:
They as producers contribute the most. Others do too, but not as much.
Unlike fish, which have a gas-filled swim bladder that keeps them afloat in the water, sharks rely upon a huge, oily liver to provide some buoyancy. The oil in the liver is lighter than water and gives the shark some buoyancy, but it is still heavier than water and will sink if it dos not actively swim.
