The correct answer is option B, that is, Ciliophora.
Ciliophora is the term used for the phylum usually known as the ciliates. Ciliates are the most complex of cells, exhibiting an elaborate cytoskeleton, cilia, two distinct types of nuclei. Ciliates are single-celled species, which at a certain phase of their life cycle, possesses cilia, that is, short hair-like projections used for food gathering and locomotion.

Answer:
Latitude provides the location of a place north or south of the equator and is expressed by angular measurements ranging from 0° at the equator to 90° at the poles. Different latitudes on Earth receive different amounts of sunlight, and are a key factor in determining a region’s climate. For example, the higher the latitude of a given place (the farther away it is from the equator), the sharper the angle of the sun’s rays that reach it, meaning that the rays of the sun are spread across a broader area. Therefore, higher latitudes receive less heat than lower latitude areas nearer the equator.
Answer:
(B) They may have binding sites for regulatory molecules that are separate from active sites.
(C) They generally have more than one subunit.
(E) They interconvert between a more active form and a less active form.
Explanation:
Allosteric enzymes are the regulatory enzymes that have a specific site for binding of modulator or effector molecule. The activity of these enzymes is altered by the noncovalent binding of modulators at the allosteric site. The binding of the modulator brings about a conformational change in the allosteric enzymes.
The relatively inactive conformation of these enzymes is called T state while the active conformation is the R state. Most of the allosteric enzymes have multiple subunits and deviate from Michaelis–Menten kinetics and exhibit a sigmoid saturation curve of V0 vs. [S].
