False. It's not always reliable. For example, in lab mice, saccharin has caused tumors. But for humans to get cancer from saccharin, we would have to take in astronomical levels of saccharin, which we, as humans, don't do.

Answer:
Negatively charged phosphate groups of two strands are aligned distantly from each other in a DNA double helix.
Explanation:
DNA double helix is formed when the complementary bases of two single DNA strands pair with each other. The formation of double-stranded structures places the negatively charged phosphate groups of two single DNA strands away from each other. This is because complementary base pairs are present between the sugar-phosphate backbones of two DNA strands of a double helix. The double-helical structure also concentrates the nitrogenous bases away from the surrounding watery medium. Altogether, these factors stabilize DNA dyad.
Answer:
True.
Explanation:
It is defined as, individuals that have certain inherited traits tend to survive and reproduce at higher rates because of these traits
Natural selection is defined as organisms developing inherited traits that better help them survive in their environment.
