Scientist study index fossils so they will get an understanding of what life was like back then.
Alignments section of the search results can you find nucleotide-by-nucleotide comparisons between your query sequence and similar database sequences
c) Alignments
<u>Explanation:</u>
Alignment is the process in which the nucleotide to nucleotide between the query sequence is analyzed and arranged in the protein sequence in the genetic material present in the body of the organism.
It is local alignment search tool to find regions of local similarity between proteins and nucleotide sequences. The programs in the genetic materials compares the nucleotide or proteins sequenced in the data and calculated the matches. The alignment can be classified as global and local alignment methods.
Answer & explanation:
1. In the nitrification process, the oxidation of ammonia (NH₃) occurs, converting it to nitrite and, subsequently, to nitrate. This process is performed by chemosynthetic bacteria (also known as nitrifying bacteria), that is, they use the energy released in nitrification to synthesize their organic substances.
2. Denitrification occurs when bacteria in the soil called denitrifiers use nitrates and turn them into nitrogen gas. Denitrification ensures the return of nitrogen to the atmosphere.
3. The fixation of atmospheric nitrogen occurs mainly with the help of bacteria. These bacteria form nodules in the cortical region of the roots of these plants, where they act by capturing atmospheric nitrogen and transforming it into ammonia (NH₃), which will be used by plants.
Answer: A virus lack the metabolic machinery common to other microorganisms
Explanation:
A virus is an ultramicroscopic particle capable of causing disease. It differs from other disease-causing organisms like bacteria, nematodes etc, because it has no metabolic system of its own but relies on its host system for survival and replication.
Hence, it is difficult for antibiotics to target and destroy viruses without harming patients, rather antiviral drug are prescribed against viruses
