Question

a chameleon uses specialized cells in its skin to change color in response to its environment. when these cells are stimulated by changes in light, temperature, or mood, they expand or contract, altering the way light reflects off the chameleon’s skin. .......... when the chameleon’s environment stabilizes, the cells relax and its color returns to normal. which choice completes the text with the most logical transition? choose 1 answer: a for example, b by contrast, c specifically, d in other words.

Explanation:

The first part of the text describes the chameleon's cells changing color when stimulated (by light, temperature, or mood). The second part describes the cells relaxing and color returning to normal when the environment stabilizes. There is a contrast between the two situations. "By contrast" is used to show a difference between two things. "For example" is used to give an illustration. "Specifically" is used to be more precise about something already mentioned. "In other words" is used to re - express something.

Answer:

B. By contrast.
