A scientist isolates a water-soluble compound from spider venom. The substance has nitrogen, carbon, hydrogen, and oxygen in its chemical structure. Based on this information, the compound is probably a .a. triglyceride
b. protein
c. polysaccharide
d. mineral salt.

b. protein

Explanation:

Proteins are biopolymers basically made of carbon, hydrogen, oxygen and nitrogen.

Triglycerides are made of a glycerol molecule esterified by three fatty acids.

Polysaccharides are carbohydrates, and therefore contain carbon, hydrogen, and oxygen.

The mineral salt contains mostly sodium chloride, although it contains some other minerals such as magnesium, potassium, iodine, among others.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
