Protist reproduction
solong [7]

Answer:

e. is mostly asexual, with sexual as a second option.

Explanation:

Protist are unicelluar eukaryotic  microorganims. Example include:

<u><em>Amoeba</em></u> <u><em>proteus</em></u>

<u><em>Euglena</em></u><em> </em><u><em>viridis</em></u>

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.

Is the neurone a cell, tissue or an organ?
cupoosta [38]

Answer:

Cell

Explanation:

Glial cells and neurons are the two types of cells that make up the nervous system. Four tasks are carried out by glial cells, which make up the nervous system's supporting framework: Give the neurons structural support. protect the neurons. A neuron is a specialized, impulse-conducting cell that is the functional unit of the nervous system, consisting of the cell body and its processes, the axon and dendrites.  Three components make up neurons (nerve cells), which perform the integration and communication processes. Axon terminals, dendrites, and axons. The cell body, also known as the soma, is their fourth component and is responsible for the fundamental functions of neurons. In the illustration to the right, a "typical" neuron is depicted. The neuron, a specialized cell created to send information to other nerve cells, muscle cells, or gland cells, is the basic functional unit of the brain. Neurons are nervous system cells that communicate information to other nerve, muscle, and gland cells. Axons, dendrites, and a cell body make up the majority of neurons.
