Question:

When do you use a semicolon vs a colon?

Cassie M.
Answer:

You can use either a semicolon or a colon to join two main clauses. Example: "I have a big test tomorrow; I can't go out tonight." A colon instead of a semicolon may be used between independent clauses when the second sentence explains, illustrates, paraphrases, or expands on the first sentence. Example: He got what he worked for: he really earned that promotion. You can only use a colon to join a main clause with a noun. Example: He got what he worked for: a promotion.

Biology

Question:

Briefly describe the main functions of proteins within the body.

Cassie M.
Answer:

Proteins are made up of individual amino acids that have been joined together. The shape of a protein is determined by the arrangement of covalent bonds and hydrogen bonds. When a protein becomes denatured (or, destroyed) the hydrogen bonds are the most affected. Proteins are used to make structures of the body (ie: collagen). Proteins are used for movement (ie: actin and myosin in contractile muscle). Proteins are catalysts for chemical processes (ie: enzymes). Proteins are used for transport of substances within the body (ie: hemoglobin transports oxygen). Proteins are used in pH regulation (ie: plasma proteins act as acid or base). Proteins regulate metabolism (ie: insulin and growth hormone) Proteins act as the body's defense mechanism (ie: antibodies of immune system).
