Read the passage and then answer the question: Lichen is composed of two organisms, an alga and a fungus. The fungus acts like a sponge, holding on to water that the alga needs. At the same time, the alga is constantly turning sunlight into energy, so the fungus, which cannot perform this function for itself, benefits from an **unwavering** energy source. Lichen has, in turn, a relationship with the tree that it grows on. The tree provides lichen with a place to grow, but the tree is unaffected. What is the meaning of "unwavering" as used in the passage? * 1.limited
2.new
3.uncertain
4.steady

4. Steady.

Explanation:

The word "unwavering" means a strong, steady, firm, or constant presence. In simple terms, it means something is always available, without fail.

As used in the given passage, the word "unwavering" means steady. This means the fungus gains a steady energy source from being attached to the alga. And therefore, there is a constant and unchanging source from which the plant can get its requirements.

Thus, the correct answer is steady.

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
