Black death victims were treated through magic, witchcraft, prayer and other methods. As for the two other options, they used medicine, but not antibiotics and radiation hadn't been discovered yet (it was discovered in the 1900's)
An "adaptation." It's the natural way that birds of flight adapt to their needs or environment which makes them more efficient.
If the graphic shows two isomers of a chemical compound with molecular formula C5H11NO2, the type of isomers that are shown is structural isomers. Option A.
<h3>What are structural isomers?</h3>
A structural isomer of a chemical is a different compound having the same number of atoms of each element as the original compound but with logically separate bonds connecting them. Previously, the same idea was referred to as a metamer.
Though they have identical chemical formulae, structural and constitutional isomers differ in how their atoms are arranged. Skeletal isomers, positional isomers, and functional group isomers are the three different categories of structural isomers.
Chain isomerism is one of three varieties of structural isomerism. isomerism in functional groups. isomerism in position.
Compounds with distinct structural formulae but the same molecular formula are known as isomers. Every sort of atom is present in the same quantity.

Algae are plant like because they contain chloroplasts and produce food through photosynthesis. Protozoa are animal like because they are heterotrophs, and are capable of moving.
