o change.\

the smithsonian museum of natural history reports the total number of insect species to be around 900,000, though it is calculated that over 10 quintillion individual insects exist. we rely on insects to pollinate our fruits, flowers, and vegetables and to provide useful products such as honey, beeswax, and silk. despite the numerous benefits they provide, some insects are better left untouched. when trying to identify whether or not an insect is harmful, one must pay attention to several important characteristics, color, smell, and sound.

some insects use camouflage to avoid detection from people and predators, however warning coloration is also an effective defensive mechanism. red, yellow, orange, and especially black are warning signs to stay away. the bright yellow colors of bees alert predators to their painful, stinging abilities. likewise, the black and orange colors of monarch butterflies, in contrast to the foliage that is green and in which they surround, issue warnings to potential predators. birds that foolishly prey on monarch butterflies will find themselves very ill from the toxins that monarch butterflies contain.

some insects produce offensive smells and unique sounds to repel people and predators invading their spaces. stinkbugs emit odors that can be sprayed several inches, linger for significant lengths of time, and smell similar to those produced by skunks. bombardier beetles excrete clouds of foul - smelling chemicals that are fatal to other

which change, if any, is needed to the underlined text?
characteristics, color, smell, and sound

○ characteristics: color, smell, and sound
○ characteristics; color, smell, and sound
○ characteristics, color: smell, and sound
○ no change

Explanation:

To determine the correct punctuation, we analyze the list of characteristics (color, smell, sound) that follow "characteristics". A colon is appropriate to introduce a list, and commas are used to separate items in the list. The original uses commas incorrectly before the list; the correct option uses a colon to introduce the list and commas between items. Option B (characteristics: color, smell, and sound) has incorrect punctuation with a colon and a comma before "and". Option C (characteristics, color: smell, and sound) misuses commas and colons. Option D (characteristics, color, smell, and sound) is a run - on. The correct option is A as it uses a colon to introduce the list and commas to separate the items in the list properly.

Answer:

A. characteristics: color, smell, and sound
