<h2>Answer </h2>
The method is by adding various small DNA chains such as TTAGGG, that develop a hairpin turn.
<u>Explanation </u>
The method is by adding various small DNA chains such as TTAGGG, that develop a hairpin turn. Telomerase is an RNA dependent DNA polymerase means an enzyme that can make DNA using RNA as a template. The ends of linear chromosomes called telomeres that protect genes from getting deleted as cells continue to divide. The telomerase enzyme attaches to the end of chromosome complementary bases to RNA template are added on 3 ends of the DNA strand.

Answer:
Cell-mediated immunity develops through a network of interactions that results in defense against microorganisms that survive within phagocytes or other cells. The response is initiated by the recognition of intracellular microorganism antigen by T cells through the histocompatibility complex. In the CD8 response, only the target cell carrying the class I associated antigen can be lysed or induced to apoptosis. In another mechanism of the cellular response, CD4 + Th1 T cells activate, for example, cytokine-infected macrophages such as IFN. When a pathogen resists the effects of activated macrophages, chronic infection may develop.
The hormonal immunity response leads to the destruction of extracellular microorganisms and prevents or decreases the spread of intracellular cells by neutralizing, opsonizing and activating the complement system.
Answer:
A) Light pollution both attracts and repels migratory birds
In addition to the many hazards that exist in urban areas, cities typically lack the food resources and cover that birds need during migration or when raising their young. ... Darkening skies at night during migration season makes it easier for birds to navigate.
Explanation:
Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by availability of food. It occurs mainly in the northern hemisphere, where birds are funneled on to specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea.
