A drug called antibiotics is a treatment used for a bacterial infection such as strep throat.
Antibiotics are medicines that are used to treat a wide range of bacterial infections.
These drugs destroys bacteria by preventing them from replicating and reproducing their copies. This way the strain is unable to continue one of its essential life function.
These substances are active against bacteria and provides a toxic condition for them to replicate.
Most populations changed from mostly light colored to mostly dark colored in the 1800s. This relates to microevolution.
A, B, & D.
Wetlands DO NOT increase the rate of extinction of mammals by creating a loss of habitat. Wetlands rather form a habitat for many organisms creating a rich microcosm of an ecosystem.
Explanation:
Wetlands are land areas that are seasonally or permanently submerged in water. They include marshlands, estuaries, deltas, swamps, floodplains, and etcetera. The plants within wetlands, such as mangrove slow down water runoff hence allowing settling down of, sediments and pollutants hence ‘cleaning’ the water.
Due to this fact that wetlands slow water movement, these ecosystems are significant in reducing flooding by ‘storing’ flood water and releasing it slowly hence acting like flood controls.
