Answer:
Yes, protists have motility.
Explanation:
Protists are <u>unicellular eukaryotic organisms</u>, which are included in a separate kingdom, as they are not included in the animalia, plantae or fungi kingdoms. They possess true nucleus, organelles, membrane and cell wall.
Many of the protistic organisms can be mobilized by modifications in their cytoplasm or by the existence of mobile appendages.
- <em>Pseudopodia</em><em>: also called false feet, they consist of modifications in the cellular form that allows them to move from one place to another.
</em>
- <em>Cilia</em><em>: these are numerous hairy structures that are found on the outside of the cell, and their coordinated movements provide the protists with mobility.
</em>
- <em>Flagellae</em><em>: unlike the cilia, these are less numerous structures, one or two, present on the outside of the cell whose whip-like movement confers movement.</em>
Protists have motility due to modifications in their cytoplasm, as well as the existence of mobile appendages, such as cilia and flagella.

Answer:
B. the nervous system
Explanation:
The nervous system is one of the body systems that has to do with the passing signal information to and fro the BRAIN and other sensory organs e.g eyes, nose, ears etc. The nervous system is what causes an individual organism to sense and respond to environmental stimuli by passing chemical signals to the brain and back to the site of effect.
According to this question, a frog is able to leap away from a snake because danger is sensed and responded to by the NERVOUS SYSTEM. Information in form of chemical signals (impulses) are passed across the brain of the animal of a possible threat, which then sends back information for the frog to react to such danger by leaping away.
The water from the 5% glucose solution will flow into the 10% one, as water molecules will flow from a region of high water potential (dilute solution) to a region of lower water potential (concentrated solution) by osmosis.
Osmosis only occurs when a differntially membrane exist, and its only about the net movement of water particles.
Therfore the result would be the water volume in the 10% glucose would rise, and the solute in the original 10% one would be less concentrated, while originally in the 5% one would be more concentrated.
