Answer:which bases pair together during transcription-Adenine and thymine form base pairs that are held together by two bonds, while cytosine and guanine form base pairs that are held together by three bonds.why is base pairing used during transcription-By virtue of complementary base- pairing, this action creates a new strand of mRNA that is organized in the 5' to 3' direction. As the RNA polymerase continues down the strand of DNA, more nucleotides are added to the mRNA, thereby forming a progressively longer chain of nucleotides. what determines the shape and properties of a protein- Peptide Bonds

The sequence and the number of amino acids ultimately determine the protein's shape, size, and function. Each amino acid is attached to another amino acid by a covalent bond, known as a peptide bond. what is a codon-a sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA molecule.how many possible codons exist in the genetic code-64 codons.what are the functions of the codons- The function of a codon is to code for amino acids. During transcription, DNA is copied to mRNA.does each amino acid have one specific codon-Because there are only 20 different amino acids but 64 possible codons, most amino acids are indicated by more than one codon. (Note, however, that each codon represents only one amino acid or stop codon.)

How does the mantle affect Earth's crust?

faltersainse [42]

Earth's mantle plays an important role in the evolution of the crust and provides the thermal and mechanical driving forces for plate tectonics. Heat liberated by the core is transferred into the mantle where most of it (> 90%) is convected through the mantle to the base of the lithosphere.

Explain the role of a hypothesis in a scientific investigation.

k0ka [10]

Answer:

A hypothesis is a testable proposition

used to explain scientific phenomena. It

may be based on previous observations

(a sort of educated guess) or it may

simply be a hunch. Most scientific

hypotheses are combinations of

observation and intuition. The important

thing is that the hypothesis be testable.

If the hypothesis is disproved through

testing, then it is discarded and a new

hypothesis is proposed. If the hypothesis

stands up to rigorous testing, then our

faith in the hypothesis is increased.

This system of careful, rigorous, and

unbiased testing of a hypothesis is what

characterizes the scientific method.

Hope it helps!

8. One of the lowest layers of Earth's atmosphere has undergone a large increase in temperature

Kamila [148]

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.
