<span>Although a star might look brighter than the Sun, a comparison of its absolute<span> magnitude might help prove that they have the same real brightness.
Absolute magnitude is a concept that compares the absolute brightness of celestial objects. The absolute magnitude of an object is defined as the apparent magnitude it would have if it were viewed at a standard distance of 10 parsecs (32.6 light-years) with no dimming of its light. The more luminous an object, the smaller the numerical value of its absolute magnitude.</span></span>

Answer:
Classification of biological organisms from most general to most specific is -
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
Explanation:
A hierarchy system of taxa or ranks of living organisms up to species level is known as taxonomic classification. It includes a higher and most generalized rank domain consist of archaea, bacteria, and eukarya. Second most generalized ranks kingdom that consist of various kingdoms.
Less generalized ranks are in order of a decrease in general and an increase in specificity are phylum, class, order, and family and the most specific ranks are genus and species.
Answer:
Humans burn fossil fuels, clear trees, change land use, creating smog that traps the carbon in the Earth's atmosphere, leading the oceans to absorb the heat and eventually end up with global warming and ocean acidification.
