Gravity of the earth = 9.78 m/s² and frictional force due to air
Answer:
The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.
Therefore, B is the answer.
"All living cells require water for survival" is NOT a statement from the cell theory.
The awnsers would be D for the first one and A for the second. Let me know if you want an explanation.
Answer:Extracting fossil fuels. There are two main methods for removing fossil fuels from the ground: mining and drilling. Mining is used to extract solid fossil fuels, such as coal, by digging, scraping, or otherwise exposing buried resources.
Explanation:
Answer:
She left Ligase enzyme out of the mixture.
Explanation:
DNA replication is the process of formation of new molecules of DNA from the existing one. This process occurs in semiconservative way i.e each new strand consist of one newly synthesised strand and one old parent strand that act as template for the formation of new strand. replication on one strand occurs continuously from 5 prime to 3 prime but on other strands it occurs discontinuously from 5 prime to 3 prime because DNA polymerase moves only in one direction from 5 prime to 3 prime. Hence in discontinuous strands gaps remained. These gaps are filled by Ligase enzyme.
Requirements for DNA replication:
DNA replications needs
Primers
DNA Polymerase enzyme
DNA helicase enzyme
Single nucleotide binding protein
dNTPs
and Ligase enzyme.
Correct choice:
She left Ligase enzyme out of the mixture.
