'Hair-like projections, called cilia trap dust, pollens, and other foreign matter and prevent it from entering the nasal cavity.

Cilia are small, fine, hair-like structures present on the surface of all mammalian cells. They are primitive in nature and can be single or numerous. Cilia play an important role in locomotion. It is also involved in mechanoreception. Organisms with cilia are called ciliates.

Cilia and flagella are motile cellular appendages found in most microorganisms and animals, but not in higher plants. In multicellular organisms, cilia help move cells or groups of cells and pass fluids and substances through them.

Cilia are generally of two types: motile (for locomotion) and non-motile (for sensory). An example of ciliated tissue cells is the epithelium that lines the lungs and sweeps away fluids and particles. Examples of organisms with cilia are protozoa, which use cilia for locomotion.

hammer [34]

This question is incomplete because the options are missing, here is the complete question:

A . Wildlife is allocated by land ownership and  privilege

B . Anyone in good standing can participate

C . Wildlife can be harvested for any purpose

D . Hunting seasons and bag limits are not  regulated

The answer to this question is B. Anyone in good standing can participate

Explanation:

The word "democratic" is used to refer to practices or scenarios in which all citizens can participate. This principle is used in hunting, fishing, and trapping in the U.S. as part of the Model for Wildlife conservation because all citizens can participate in these activities, which means access does not depend on privilege or social status. Also, due to this, regulations and laws regarding these practices must be followed by all citizens. Moreover, participation in these can only be restricted if the individual has been sanctioned or it is not in good standing. According to this, the correct answer is B.

katrin2010 [14]

Answer:

c. Agent Lopez’s entire compensation must be recouped because Ralph disenrolled within 3 months of enrollment.

Explanation:

Health plans, such as Top Choice Medicare Advantage, provide a document listing all clauses relating to the plan, such as withdrawal deadlines, service agreements, reimbursement, among other things. In the case of Top Choice Medicare Advantage, there is a clause stating that the agent responsible for enrolling the client in the plan will have compensation restored if the client cancels the enrollment within 3 months. With this, we can conclude that, in relation to the case shown in the above question, Agent Lopez's full compensation must be recovered because Ralph annulled himself within the three month period.
