Number the steps of stellar evolution in the correct order. Stellar core heats as it grows; nuclear fusion begins and a star is born.
Nebular cloud of gas and dust.
Nuclear energy runs out; death; possible supernova.
Other gas and matter of the nebular cloud begin to rotate around the protostar, forming a flattened, disk.
Condensed material begins to combine and form a core center. As it warms, a protostar is formed.
Cloud collapses under the force of its own gravitational attraction; usually triggered by a supernova. (Subject is actually earth and space science)

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

whole number data type

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type
