Answer: According to sources, the most probable answer to this query is that evolution happens because when life came it sought for survival. Now, this is through mutation which causes random DNA sequences leading to genotypic and phenotypic changes. Natural selection as relation to adapting to the selection forces of the environment. And when these factors is added by the niche and other large case scenario to cause major anatomical changes, speciation comes through. And that, the process of evolution. And how it is a mechanism and an intermediate interaction with the environment.
Explanation:
They will become extinct and the level of oxygen in the atmosphere decreases and. carbon emissions increases
Answer:
Bacteria and Archaea
Explanation:
The prokaryotes are classified into two domains, the bacteria and the archaea domains. This makes them unique as the other organisms fall into one of the three domains, not in two of them. The prokaryotes come in many different shapes. They all do fall into three categories, bacilli (which are the rod-shaped prokaryotes), spirilli (which are the spiral-shaped prokaryotes), and cocci (which are the spherical shaped prokaryotes).
Answer:
RNA molecules are made of nucleotides. (Ans. C)
Explanation:
RNA, which is also known as ribonucleic acid is found in cytoplasm of the cell, and synthesized in the nucleus. It is shorter, and a single stranded molecule. It is composed of one or more nucleotides which are linked together by phosphodiester bonds.
In RNA, the ribonucleotide contains pentose sugar ribose, four nitrogenous bases (A,U,C,G), and a phosphate group. RNA plays many types of role in cells, but mainly involved in the translation process, and it's regulation which is known as protein synthesis.
