Answer;
-Pellicle
Explanation;
-Protist cells may contain a single nucleus or many nuclei; they range in size from microscopic to thousands of meters in area. Protists may have animal-like cell membranes, plant-like cell walls, or may be covered by a pellicle.
-On a paramecium's exterior is found the pellicle. The pellicle is stiff to maintain the paramecium's shape and provide stability but it is also flexible to allow movement. It also acts as an attachment site for external organelles such as cilia.
Answer:
I believe the first one would be incomplete dominance, the second would be multiple alleles, and the third would be codominance.
Explanation:
The first one would be incomplete dominance because the child has a blend of the man's straight hair and the woman's curly hair, but neither of two hair types are completely dominant (if that makes sense).
The second one would be multiple alleles because, well, there are multiple alleles listed (more straightforward than the other two).
And the third one would be codominance because the traits of red color and white color are equally dominant.

The part to test is the hypothalamus and the preoptic area
Information on the surrounding temperature is brought from the periphery by nerve afferents from cutaneous thermoreceptors (sensitive to changes in skin temperature). But the most important element in the perception of thermal information seems to be the fact that there are heat-sensitive or cold-sensitive neurons in the brain. Very high densities of thermosensitive neurons are found in the anterior hypothalamus and the preoptic area.
There are two types of heat-sensitive neurons, those that are sensitive to heat ("hot" neurons, which considerably increase their activity [electrical discharges] when they are warmed up and decreased when they are cooled) and those that are sensitive to cold ( "cold" neurons that do the opposite).
