Sandra was quite overwhelmed by her final exam. many of the test questions were difficult to answer, and she felt like she would not be able to complete the exam. what would you suggest sandra do?
sandra should guess answer “c” on all of the questions, because teachers use answer “c” as the correct answer most often.
a.
sandra should guess answer “c” on all of the questions, because teachers use answer “c” as the correct answer most often.
c.
sandra should leave the questions she is unsure about blank because unmarked questions are never counted wrong.
b.
sandra should answer the questions in numerical order so that she does not skip any. it will not matter if she doesn’t finish in time.
d.
sandra should answer the easy questions first. then she should go back and reevaluate the more difficult question.

The correct answer is option letter D (Sandra should answer the easy questions first. Then she should go back and reevaluate the more difficult question). When taking a final exam with many difficult questions, one should try and answer the easy questions first and then go over the exam to answer the more difficult ones we left to the last. Options A, B, and C are incorrect. Option A is wrong, since the fact that “teachers use answer “C” as the correct answer most often” is not totally true. Option B is wrong because time does matter in a final exam; meeting the deadline is far more important than answering in numerical order. Option C is wrong, since unmarked questions are in fact counted wrong.

answer: b (host)

viruses use the cells of living organisms to reproduce. the cell which is used by virus is called as "host cell". it is a living cell in which virus multiplies, example bacteria, plant or an animal cell.

in this, the virus is a parasite, which uses host cell for its benefit (reproduction) by using the cell machinary of host cell.
