Answer:
connective tissue comes in a vast variety of forms, yet they typically have in common 3 characteristic components: cells, large amounts of amorphous ground substance, and protein fibers
Answer:
an amino group and an R group
"Each of the 20 amino acids has a central carbon atom with four covalent bonds. These bonds link the carbon atom to an amino group ( NH2 ), a carboxyl group ( COOH ), a hydrogen atom, and an R group. The R group can be a carbon side chain, a hydrogen atom, or a functional group. " -------- from my textbook.

Hello. You forgot to add the diagram.
The diagram is attached below.
Answer:
1. examination of homologous fossilized structures of primitive horses
Explanation:
As you can see in the diagram, to show the stages of the development of the modern horse, a comparison is made between the forelimb structure and the molar tooth of these horses (related to the adult form). These two factors of comparison establish the representation of fossilized homologous structures of primitive horses.
As you may already know, homologous structures are different body structures from different animals that have a strong similarity (because they are inherited from a common ancestor). When these animals die and these structures are conserved, we can say that they have been fossilized.
As the forelimb structure and the molar tooth of the horses shown in the diagram are homologous structures that were fossilized, we can say that option 1 is the correct answer to your question.
