Cilia are found in certain a. protozoa.
In the field of biology, cilia can be described as thread-like projections which are membrane-bound, found in mammals and various microorganisms referred to as ciliates.
Protozoa are eukaryotic organisms that are single-celled. The protozoa can either live freely or choose a parasite to live in.
Cilia are present in certain protozoa in order to help the protozoa in movement. The cilia also help the protozoa in gathering food for nutrition. The cilia also make it possible for protozoa to attach to a surface. Sensations in a protozoa can also be generated through cilia.
The cilia cover the entire surface of the protozoa cell.

The largest number of cells in division are found in the skin. This is because these cells are the ones that are most exposed so they die and are replaced constantly. In addition, it is the most extensive organ of the body and its shape or density varies from one area to another.
I hope my answer can help you.
C is the answer. I think this is where babies occur.
C. electron transport and chemiosmosis
Chemiosmosis<span> involves movement of </span>ions<span> across a </span>semipermeable membrane<span>, down their </span>electrochemical gradient<span>. More specifically, it relates to the generation of </span>adenosine triphosphate<span> (ATP) by the movement of </span>hydrogen<span> ions across a </span>membrane<span> during </span>cellular during respiration<span> </span><span>.</span>Hydrogen ions, or protons<span>, will </span>diffuse<span> from an area of high proton concentration to an area of lower proton concentration, and an </span>electrochemical concentration gradient<span> of protons across a membrane can be harnessed to make ATP. This process is related to </span>osmosis<span>, the diffusion of </span>water<span> across a membrane, which is why it is called "chemiosmosis".</span>
