Answer:
Locomotion and feeding
trapping dust
Explanation:
Paramecium is an organism that belongs to kingdom protoctista. They swim in water through beating of the cilia. They also feed on tiny organisms that are swept into the oral groove through beating of the cilia.
During gaseous exchange in mammals, along the nasal passage are cells with cilia that trap dust particles and beats to move mucus and dust trapped up to the larynx.
They have both. The actual tail of a snake is a relatively short bit at the end, behind the anus, similarly to any other vertebrate animals. Most of the snake's body is the torso, and the neck is also short tho
Potential K- strategists include humans.
K- strategist:
The term "K-selected" or "K-strategist" refers to species whose populations vary at or close to the carrying capacity (K) of the ecosystem in which they live. Compared to r-selected species, K-strategist species have remarkably constant populations and generate relatively few offspring, but those offspring typically grow to be rather big. Lengthy gestation durations of many weeks, slow development (and hence prolonged maternal attention), and long longer lifespans are traits of K-selected species. Additionally, they typically live in ecological groups that are generally stable, including premature or climax forests.
R-strategist:
They are creatures that have high reproduction rates followed by high death rates, resulting in populations with wildly variable numbers, according to the concept of r-selected species (or r-strategist). This term is based on the concept of "r," a variable in the ecology of animal populations that denotes a species' maximal reproductive potential. The populations of r-selected species will be small outside of the mating season. R-selected organisms begin to generate a lot of progeny as soon as reproduction begins.
Therefore it is concluded that the final choice is option C, i.e., humans.
