The correct answer is: Replacement of defective genes with normal genes
Recombinant DNA molecules are made in laboratory by the methods of genetic recombination such as molecular cloning. The aim of these methods is to bring together genetic material from different sources, creating “combinations” that usually couldn’t be found in the genome. The process of recombination is possible because, DNA molecules from all organisms share the same chemical structure (nucleotides are same among different species, difference is only in the nucleotide sequence).
Epithelial tissue is the type of tissue that lines the body cavities.
Answer:
<em>b. Generally, the quality of life is directly related to an area's energy use per person.</em>
Explanation:
The quality of life is directly proportional to the amount of energy being used. The more the amount of energy the more the quality of life will be enhanced. For example, the life of a person who uses much electricity and fuels will be better than the person who cannot use electricity or fuel. Hence, the correct option is b.
Answer:
The options are
a.cooling of the power plant
b.mining of uranium
c.storage of radioactive waste
d.monitoring the reactor
The answer is b.mining of uranium
Explanation:
Uranium is known as a radioactive element which is used as a fuel to power a nuclear energy plant. Mining of uranium could cause it to mix with air and water which results in contamination.
When contamination occurs and it gets into the body of humans or animals by inhalation or ingestion it poses a high risk of cancer and kidney damage.
