Explain the role of bacteria in the nitrogen cycle
Oksanka [162]

Bacteria is important because this bacteria binds hydrogen molecules with the gaseous nitrogen to form ammonia in the soil.  During assimilation, or when plants take up nitrates from the soil, bacteria aid in the process with the plants in making ammonia. Animal wastes is also a major place where bacteria thrives and produces ammonia. The process in which assimilation occurs in plants, and then bacteria converts the nitrates to ammonia is called ammonification.  From the conversion of ammonia to nitrites, bacteria also aids in this process called nitrification. The nitrifying bacteria mostly present in soils, oxidize ammonia into nitrites, and from nitrites to nitrates.

Finally, the process of denitrification also has bacteria present to aid in converting nitrates back into a gaseous form of nitrogen in the atmosphere.

Which characteristic differentiates amphibians from reptiles?
Stells [14]

Option D – amphibians may use their skin for gas exchange is the characteristic feature of amphibians that differs from reptiles.

Explanation:

The amphibian skin is moist, thin and marbled and supplied by blood vessels running on its surface. The moisture present in the skin dissolves the oxygen present in its surrounding which is absorbed by the blood vessels. Special glands help the amphibians to keep the skin moist.

The very thick and tough scales present on the reptiles prevent them to absorb oxygen through their skin. Hence, they breathe and respire through their lungs.

Amphibians have three-chambered heart. They do not develop amniotic eggs. Adult amphibians although spend much time on land, they breed only in water due to the absence of amniotic sac .

Savatey [412]

<u>Answer</u>:

"It increases the mutation rate"  is an advantage of  sexual reproduction

<u>Explanation</u>:

The basic thing of evolution is fundamental, as it helps in generation of genetic variation on which the selection can act. Sexual reproduction leads to genetic diversity, and this genetic diversity leads to increase the mutation rate. Genetic diversity occurs because of two various cells which are combining together and biological assortment which happens at the time of cell division. Neutral genetic diversity in the population leads to high mutation rate.
