Which statement describes scientific studies about fossil fuels that are related to politics

Biology
1 answer:
Olin [163]3 years ago
4 0

Answer:

Fossil fuels, including coal, oil and natural gas, are currently the world's primary energy source. Formed from organic material over the course of millions of years, fossil fuels have fueled U.S. and global economic development over the past century. Yet fossil fuels are finite resources and they can also irreparably harm the environment. According to the U.S. Energy Information Administration, the burning of fossil fuels was responsible for 76 percent of U.S. greenhouse gas emissions in 2016. These gases contribute to the greenhouse effect and could lead to potentially catastrophic changes in the Earth’s climate. Technologies such as Carbon Capture and Storage (CCS) may help reduce the greenhouse gas emissions generated by fossil fuels, and nuclear energy can be a zero-carbon alternative for electricity generation. But other, more sustainable and less risky solutions exist: energy efficiency and renewable energy.

FrozenT [24]

Answer:

1. replication

2. gene

3. strand polarity

4. translation

5. complementary base pairing

6. chromosome

7. antiparallel

8. transcription

9. allele

Explanation:

1. Replication is the process by which DNA is duplicated or the process of making another copy of DNA.

2. Gene is the physical unit of heredity i.e a segment of DNA transferred from parents to offsprings. A gene also encodes a useful products such as protein.

3. A DNA strand is a polar molecule, which is attributed to the phosphate group at the 5'-end of DNA and the hydroxyl group at the 3'-end of DNA.

4. Translation is the process whereby the information in a mRNA molecule is used to synthesize a protein.

5. Complementary base pairing is a phenomenon whereby Adenine (A) binds to thymine (T), guanine (G) binds to cytosine (C).

6. A chromosome contains of single long molecule of DNA coiled together around histone proteins. The chromosome is associated with different types of proteins.

7. In the double-stranded DNA molecule, one strand runs from 5' to 3' and the other runs from 3' to 5'. This is called ANTIPARALLEL nature of DNA.

8. Transcription is the process by which a DNA molecule is used to synthesize a mRNA single strand.

9. Allele is the alternative or contrasting form of a gene. Each allele is contributed by each parent
