Answer:
A. Lipid A
Explanation:

The lipopolysaccharide has three parts out of which lipid A is the toxin one. Lipid A is embedded in the outer membrane through its fatty acids. When lipid A enters the blood stream of the host cell, it leads to septic shock. Lipid A is heat stable and highly toxic.
Because they take place at an atomic level and are unable to be seen by the human eye

They CREATE the tectonic even some or part of an oceanic are being subjected.
"...Almost entirely hidden under the sea is a worldwide chain of low mountains with lines of volcanic activity running along their crests. Their worldwide extent was recognized in the mid-20th century, and shortly afterward the mid-ocean ridges were assigned a starring role in the new theory of plate tectonics. The ridges are the divergent zones where oceanic plates are born, spreading apart from the central valley, or axial trough...."

Answer:
<h2>B. Carbon dioxide emissions and global warming:We have already lost some 80 percent of the coral reefs in the Caribbean over the last three decades, and losses in the Pacific Ocean are also widespread. Reefs are like cities, with some parts growing and some parts being destroyed. When the net growth is positive, reefs can persist. Amazingly, coral reefs are threatened by such atmospheric conditions as..</h2>
