Common characteristics supporting the idea that the first land plants were related to green algae include All of the above. Thus, option "D" is correct.
The Green algae are responsible for the main supply of oxygen in the atmosphere. There are tiny organisms called cyanobacteria (or blue-green algae) which photosynthesise carbohydrates for their nutrition and growth using sunlight, water, and carbon dioxide.
The waste product of cyanobacteria is the oxygen of the atmosphere.
Thus, option "D" is correct.

b. False
It is true that in the DNAisolation process, cells are mixed with sodium chloride (i.e. NaCl) because the sodium (Na ) neutralizes the negative charge of DNA.
DNA extraction is a method of separating DNA from cell membranes, proteins, and other cellularcomponents using physical and/or chemical methods from a sample. In 1869, Friedrich Miescher isolated DNA for the first time.
The ability to extract DNA is critical for studying the genetic causes of disease and developing diagnostics and drugs.
It is also required for forensicscience, genome sequencing, detecting bacteria and viruses in the environment, and determining paternity.
Because sodium (Na+) neutralizes the negative charge of DNA, cells are mixed with sodium chloride (i.e. NaCl) during the DNA isolation process. It makes homogenization easier.
Thus, the given statement is true.
