<h3><u>Answer;</u></h3>
Gene therapy to correct defective genes that cause diseases.
<h3><u>Explanation</u>;</h3>
- Gene therapy refers to the procedure that involves the introduction of nucleic acids (DNA or RNA) into the cells of an organism for the purpose of correcting abnormalities, such as a mutations or in other words to treat a genetic disease.
- Gene therapy entails bringing a normal and functional gene known as a trans-gene into a cell with altered gene. Another method can bring RNA capable of partially regulating or blocking the expression of an altered gene.
- The nucleic acids are introduced into the patient's cells by means of a viral vector or injected directly into the cells in the form of naked DNA.
The survival of every ecosystem is dependent on the producers<span>. Without </span>producer s<span>capturing the energy from the sun and turning it into glucose, an ecosystem could not exist.

This sounds like a test cross. Because P is dominant, the purple flower could have a genotype of Pp or PP. If all of the offspring of the test cross are purple, then the purple flower has genotype PP. If half of the offspring of the test cross have purple and half have white, then the purple parental flower's genotype is Pp.
Answer:
B.) Burning fossil fuels causes a decrease in the pH of ocean water making it more acidic
