According to the passage, the main function of a rhizoid is to
The answer to this question is stated in the first paragraph(line 10). When you read the passage, try to understand the relationship between the ideas. In other words, "What does a rhizoid do?" ; it supports the plant.

What does the statement "The absence of a midrib is quite common in the bryophytes" in lines 11-12 mean?
To answer this question correctly, look for the closest synonym or the restatement of the statement. Choice (A) the most logical.

It can be inferred that tundra is well suited for which of the following?
By reading the information in the first paragraph, (C) can be inferred. Liverworts are found on the floors and tree trunks of tropical forests because they do not have a strong root system; therefore, the tundra in Antarctica is a suitable place for them.

In line 9, the word "host"could best replaced by which of the following?
The word "host" means "group" in this context. Although all the other choices are attractive, they are not the correct answer.
Read the following paragraph and answer the question at the bottom
1. The leading causes of amnesia are either physical or psychological. In
2. antergrade amnesia, the subject is unable to recall the events that occur after
3. a shock or an injury to the brain; however, past memories will not be lost. In
4. retrograde amnesia, the patient is capable of recalling events that occurs after the
5. trauma; interestingly enough, information stored before the shock, is lost and
6. cannot be retrieved. In paraamnesisa, established memories are contorted. In
7. psychogenic fugue, the subject may venture into a new lifestyle, trying to
8. repress memories which lead to trepidation. The events happening during
9. psychogenic fugue are non-retrievable. Nonetheless, the experiences that
10. happened before the onset can be recovered. Among the most popular
11. treatments for psychologically related amnesia are psychotherapy, the use of
12. drugs, and hypnosis.
