The answer is: pseudostratified ciliated columnar epithelial cells.
We can find these type of cells in the upper part of the trachea and bronchi, and through the whole upper respiratory tract (nasal cavity included).
Their job is to produce a mocous secretion (look up <em>cilia</em>) help us to stop external, microscopical, materials from entering our lungs, and so we can sneeze and cough them away.

Answer:
1. Bats and cats: <em>Homology</em>
2. Whales and sharks: <em>Analogy</em>
Explanation:
In Biology, homology refers to <u>the similarity of features from different species of organisms that share a common ancestor</u>. This is the opposite of analogy, which refers to <u>a feature that has a similar function but is not derived from a common ancestor</u>.
In this case, bats and cats have forelimbs adapted for locomotion. This is a case of homologous characters because they both are descendants of tetrapods - four-limbed animals. Therefore, even though cats and bats look completely different, they both share a similar feature: forelimbs, a characteristic feature from their common early mammalian ancestors.
On the other hand, whales (mammals) and sharks (fish) do not share a common ancestor. So, the fins are analogous structures: both have a similar function because both have adapted to an aquatic environment but they have completely separate evolutionary origins.
Answer: Unipolar depression
Explanation: Kelly suffers from unipolar depression which means that she does not go through the various opposite conditions / states as is the case with bipolar depression. Kelly has problems with severe depression, a depressive disorder where, after a period of such a condition, there is no the opposite euphoric conditions or states. Unipolar depression occurs periodically and can dramatically complicate daily life functioning as is the case with Kelly. The symptoms of this mental disorder which is actually the major depressive disorder that occurs in the episodes are, for example, not finding pleasure and enjoying the things we have done before that have caused us pleasure, too much sleep, depressed moods for most of the day or most of a certain period, loss of appetite.
