ANSWER: A. A factory does not clean its workspace every night.
EXPLANATION: The National Consumer's League is an American consumer organization founded in the year 1899. It advocates for consumers on marketplace and workplace issues. They voiced for safer and secure workspace, fair working conditions, protected workers from exploitation by employers, promoted food inspection and advocated for child labor restrictions, the limiting of work hours and establishing minimum wage laws for women. So, it can be guessed that they are protesting for factory's clean workplace.

body. It is a glass-like, translucent , bluish-white cartilage that can be

is also present in the ribs, nose, larynx and trachea.
Answer: There are 4¹⁰⁰ possible strands, approximately 1.61x10⁶⁰
Explanation:
This is a combinatorics problem. Each nucleotide has the possibility of being one of the four common nucleotides, adenine (A), guanine (G), thymine (T) and cytosine (C).
If the strand would be 1 nucleotide long, the possibilities would be 4, one for each possible nucleotide. If the strand would be 2 nucleotides long, for each nucleotide on the first position there would be four possible nucleotides on the second position, giving 4x4=4²=16 possible strands.
For 3 nucleotides long you have 4 possible nucleotides for each of the 2-nucleotide-long strands, 4x4x4=4²=64 possible strands. Following that pattern, for a 100 nucleotide long DNA strand, there would be 4x4x...x4x4=4¹⁰⁰ possible strands.
Hawaii sits smack dab in the middle of the Ring of Fire, a 25,000 mile boundary around the Pacific Ocean where tectonic plates meet to create volcanoes, earthquakes, and deep ocean trenches. Since Hawaii sits in the middle of the Pacific plate, not on a tectonic plate boundary, its volcanoes form in a different way.
