Answer:

Gene therapy

Explanation:

Gene therapy can be defined as the methodologies used to modify/restore the expression of target genes and thus cure and treat genetic disorders. Gene therapy approaches consist of delivering specific nucleic acids (either RNA or DNA) in the cells of the individual to be treated. Some of the most important gene therapy approaches include the use of small interfering RNAs (siRNAs) in order to block target gene expression, adenovirus vectors to insert genes into host cells, the use of the CRISPR-Cas9 genome editing system to insert specific sequences by the mechanism of homologous recombination, etc.

SOMEONE PLEASE HELP!!!
MatroZZZ [7]

Answer:

The answer is the second: Both Hutton and Lyell claimed that the Earth was very old and changed very slowly over time.

Explanation:

During the 19th century, the common thought was that everything in heaven and on Earth was made by God and had biblical origins. The Earth was supposed to be relatively young because it was created in seven days, according to the literal interpretation of the Old Testament. Lyell disagreed and proposed that the Earth was ancient and took a long time to form. Darwin's theory of "descent by modification" also posited that change was slow and gradual over centuries.

I hope I have helped you, can you put that this is the smartest answer please.

Answer;

C6H12O6 (Glucose)

Explanation;

Cellular respiration is the process by which plants and animals use to generate energy in the form of ATP which is used to drive cellular activities such as growth and movement.

The process takes place in the mitochondria, nutrients such as glucose are used in presence of oxygen (aerobic respiration) to generate energy in the form of ATP , the process also yields water and carbon dioxide as by products.
