When comparing two species, the presence of which type of structures indicates descent through modification from a common ancest
MakcuM [25]

Answer:

Homologous characters indicate descent through modification from a common ancestor.

Explanation:

Homologous characters have the same fundamental structures. They also share the same relations with adjacent structures, and they have the same embryological development.    

These structures might show variations between organisms exhibiting them, according to their function and to the environment in which the organism lives.  

These homologous characters are common in organisms related and that share a <u>common ancestor</u>.  

For example, whales, humans, and horses all have the same bones in the same order, but they matured differently in later embryological development. This is an example of homologous characters.

The graphic shows two isomers of a chemical compound with molecular formula C5H11NO2. Which type of isomers are these?
Marysya12 [62]

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.
