Answer the following question given this paragraph: Most mirrors are plane mirrors. A plane mirror has a flat reflective surface and forms only virtual images. The image formed by a plane mirror is also life sized. But something is different about the image compared with the real object in front of the mirror. Left and right are reversed. Look at the man shaving in Figure below . He is using his right hand to hold the razor, but his image appears to be holding the razor in the left hand. Almost all plane mirrors reverse left and right in this way. Q: A plane mirror has a flat reflective surface and forms only which kind of images? Choices: - enlarged - spherical - reduced - virtual A:
(Answer)
virtual

Ans: cubic
(Q).
Answer the following question given this paragraph: Because carbohydrates have a carbonyl functional group and several hydroxyl groups, they can undergo a variety of biochemically important reactions. The carbonyl group, for example, can be oxidized to form a carboxylic acid or reduced to form an alcohol. The hydroxyl groups can undergo substitution reactions, resulting in derivatives of the original compound. One such derivative is Sucralose, an artificial sweetener that is six times sweeter than sucrose; it is made by replacing two of the hydroxyl groups on sucrose with chlorine. Carbohydrates can also eliminate hydroxyl groups, producing alkenes. Q: Because carbohydrates have a carbonyl functional group and several hydroxyl groups, they can undergo a variety of biochemically important reactions. the carbonyl group, for example, can be oxidized to form a carboxylic acid or reduced to form this? Choices: - glucose - sucrose - caffeine - alcohol A:
(A).
alcohol
Ques:Answer the following question given this paragraph: Magnetite crystals of different ages and on different continents pointed to different spots. The simplest explanation is that the continents have moved. Q: Magnetite crystals of different ages and on different continents pointed to different spots. the simplest explanation is that the continents have done what? Choices: - reacted - changed - evolved - moved A:

Ans:moved
Answer the following question given this paragraph: Q: What orifice in the body is particularly helpful in both digestion and respiration? Choices: - nostril - nose - anus - mouth A:
