Answer:
The correct answer is the second option - glycerol and fatty acids combine to form lipids.
Explanation:
Lipids are a polymer or macromolecule, and the smaller pieces, or monomers, that make up lipids are glycerol and fatty acids.
Option 1 is incorrect because nucleotides are the monomer for nucleic acids, not proteins.
Option 3 is incorrect because amino acids combine to form proteins, not nucleic acids.
Option 4 is incorrect because polysaccharides are polymers (the monomer for carbohydrates is monosaccharides).
Hope this helps!

A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6.

Explanation:
Answer:
fills with blood during arousal and causes an erection.
Explanation:
The corpus spongiosum is a mass of tissue present in the under part of the penis (male sexual structure) that is actively responsible for erection of the penis. The corpus spongiosum, in conjunction with the corpus carvernosa works to maintain erection of the penis in males.
During sexual arousal, the corpus spongiosum, which surrounds the urethra (passage for urine and semen) helps keep the urethra open for semen to be released while the carvernosa becomes filled with blood. This constant flow of blood into the carvernosa makes the penis enlarge and assume an erect position.
