DNA isolation is a process of purification of DNA from sample using a combination of physical and chemical method while on the other hand, Polymerase chain reaction (PCR<span>) is a technique used in molecular biology to amplify a single copy or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence.</span>
Answer: O cytoplasm: protects cell structures
Explanation:
Distillation is the process of separation in which the volatile parts of a liquid mixture are separated by selective boiling and condensation. This process may lead to partial separation or complete separation. Distillation is employed for a considerable number of commercial processes such as the production of alcohol, kerosene gasoline, etc. During a distillation, it is important that a drop of condensate be suspended from the thermometer because it allows steady distillation and a stable temperature.
The second option because solar energy is a renewable source which can be used again.
The third option because walking to work or school would mean that you aren’t using Carbon Dioxide (which is harmful to the environment)
And the 4th option because even though using trains and buses uses Carbon Dioxide, more people can go into one transportation (and it’s public) and they don’t need to use vehicles which is mostly for individuals (mostly only one person driving a car. No passengers)
The answer would be the Gastropoda
