Answer:

The correct answer is the second option axon.

Explanation:

Neurons or nerve cells is a cell that transfers electrical signals. Nerve cells are the structural and functional units of the human nervous system. Every nerve cell is made up of 3 parts, a cell body called soma, dendrites and an axon.

The soma or cell body forms an elongated projection, called axon. Axon is responsible for sending electrochemical signals with the help of elaborate ion transport. Some nerve cells have a myelin sheath covering around the axon to facilitate signals faster.

Thus, the correct answer is the second option, Axon.

Fern spore germinates into prothallus.

Explanation:

Ferns are members of phylum pteridophyta, the vascular cryptogams.

These are first land plants which are known to have a distinct conducting system of xylem and phloem.

They reproduce by forming spores that germinates into a heart shaped gametophyte.

The gametophyte of the fern is called prothallus.

The heart shaped gametophyte has root like structure called rhizoids.

These rhizoids anchor the gametophyte to the substratum.

The basis for dividing the prokaryotes into two domains is:

SSSSS [86.1K]

<h2>The Genome Sequences</h2>

Explanation

<em>Answer (d) is right answer.</em>because the prokaryotes into two domain is the difference in genome sequences.

The two prokaryote spaces, Bacteria and Archaea, split from one another Archaea are likewise different, however none are <em>pathogenic and many live in outrageous conditions. </em>
Prokaryotes are genuinely more straightforward cells than eukaryotes, and their genomes are a basic, single hover of primarily coding successions of DNA, which is repeated and coded into proteins quickly.
Archaea flourish in various limits such as heat, cool, corrosive, base, saltiness, weight, and radiation.
These diverse ecological conditions after some time have permitted Archaea to develop with their outrageous surroundings so they are adjusted to them and, actually, make some hard memories adapting to less extraordinary conditions.
Most extremophiles are microorganisms (and a high extent of these are archaea), however this gathering additionally incorporates eukaryotes, for example, protists (e.g. green growth, parasites and protozoa) and multicellular life forms.
Archaea is the fundamental gathering to flourish in <em>outrageous situation</em>
