Explanation:
John Dalton proposed the theory of matter which is popularly known as the Dalton's atomic theory. In the atomic theory, Dalton identified from his experiments on gases that every matter is made up of small indivisible particles called atoms. These atoms are the smallest fractions of a matter.
- All the atoms of an element are all alike.
- Compounds form from atoms by simple whole number combinations alone.
- Chemical combination of atoms involves the rearrangement of reactants.
Therefore, using these clues you should be able to answer the question.

Answer:
<h2> Replication: DNA into DNA, and RNA primer are required;</h2><h2>Transcription/RNA processing: pre mRNA and then mRNA;</h2><h2>Translation: tRNA, rRNA</h2>
Explanation:
1. During replication, a semi-conservative copy of a DNA molecule is made with the help of various enzymes and RNA primer.
2. Transcription/RNA processing: mRNA
During transcription, the DNA "message" ( in the form of codon) is copied into mRNA.
3. Translation: tRNA, rRNA
During translation, the information carried in the mRNA is translated into protein with the help of molecules of tRNA and rRAN to build a protein on the ribosomes.
Answer:
Troposphere is the lowest layer of Earth’s atmosphere that has undergone a large increase in temperature due to the presence of greenhouse gases.
Explanation:
Troposphere (0 to 12 km) where we live is the lowest layer of earth's atmosphere, which is closest to the earth's surface contains half of the atmosphere. Here most clouds are found and almost all weather occurs. Atmosphere contains approximately 78% of nitrogen , 21% of oxygen and 0.9% of argon. Gases like carbon dioxide, nitrous oxides, methane, ozone and the water vapor constitutes the rest of the atmosphere. Many small particles called aerosols are also there which include dust, spores, pollen, volcanic ash, smoke etc.The greenhouse effect is a natural phenomenon that keeps the temperature on the earth suitable for supporting life. The greenhouse gases includes both natural and man-made gases like carbon dioxide
, methane, nitrous oxide, chlorofluorocarbons, hydrochlorofluorocarbons, ozone, water vapour. They absorb radiation in the atmosphere and create the green house effect. The thermal infrared radiation emitted by the Earth’s surface and the atmosphere is absorbed by greenhouse gases. They trap heat within the surface-troposphere system preventing it from escaping back into space. This is called the greenhouse effect, which increases the temperature of the lower atmosphere.The increase in the atmospheric concentrations of greenhouse gases due to human activity has caused an increase in the natural greenhouse effect. As a result, the atmosphere is trapping too much heat which increases the temperature of the Earth.
It forms proteins, thats youre answer.
