Answer: Option E
Maintaining very long telomeres promotes cancer cell formation.
Explanation:
Telomere refers to either of the sequences of DNA at each end of a eukaryotic chromosome.
Usually, in eukaryote chromosome replication, telomeres are not replicated.
Hence, they are usually lost resulting in the shortening of the telomere ends after repeated cycle of cell division. This also leads to cell aging and stoppage of cell division.
The shortening of telomere combined with stoppage of cell division, and cell aging initiation prevent CANCER, which thrives on lengthy telomeres
Answer: D. I, II, III, IV, V, and VI
Explanation:
Oxygen is recquired for cellular respiration and break down nutrients like sugar to create ATP. Organisms from all kingdoms like Bacteria, Archea, Plants, Protists, animals and fungi can use cellular respireation.

Explanation:
In the lytic cycle, a phage acts like a typical virus: it hijacks its host cell and uses the cell's resources to make lots of new phages, causing the cell to lyse (burst) and die in the process. Entry: The phage injects its double-stranded DNA genome into the cytoplasm of the bacterium.
Half life is the time taken by a radioactive isotope to decay by half of its original mass. In this case the half life of carbon-14 is 5500 years.
The original mass is 30 g and the new mass is 3.75 g.
New mass = Original mass × (1/2)^n, where n is the number of half lives;
3.75 = 30 × (1/2)^n
1/8 = (1/2)^n
n = 3
Thus, the time taken will be; 3 × 5500 = 16500 years.
