What is the initial stage of all stars? nebula black hole supernova white dwarf

Nebula

Explanation:

Nebula is a stellar nursery. Stars take birth in the molecular cloud of dust and gases -Nebula.

This molecular condenses and forms a core which spins and gathers even more mass and becomes bigger. This process increases temperature and pressure at the center which ultimately starts nuclear fusion reaction giving birth to a star which liberates energy in the form of heat and light.

Black-hole is the end stage of a massive star.

Supernova is a stage which precedes formation of a neutron star or a black-hole for a massive star.

White dwarf is the end stage of an average mass star like sun.

the answer is c cumulus. cumulus clouds can be seen on a gray and rainy day, because cumulus clouds create thunderstorms. give me brainliest if right.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
