Explanation:

Protist are unicelluar eukaryotic  microorganims. Example include:

Amoeba proteus

Euglena viridis

Dinoflagellates, etc.

Among the species of Protists, each species exhibit a unique way of reproduction. Generally, in Protist there are two types of reproduction, these are asexual reproduction and sexual reproduction. With asexual reproduction being the primary mode of reproduction in most protists.

Protist reproduce asexual by binary fission or by budding.

Binary fission occurs when a single protist divides its nucleus and then divides itself into two separate organisms.

Budding occurs when a new organism grows from the body of the parent organism. The new organism may separate from the parent or remain attached, forming colonies.

They also reproduce sexually by conjugation.

Sexual reproduction by conjugation requires two parent organisms contributing to the genetic material of the offspring. The essence of conjugation is to produce a new offspring with a wider genetic variability i.e the offspring being genetically different from the parent organisms.

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.
