The two cell surface modifications we can expect to see on the outside of the plasma membrane is a signaling molecule, or ligand.

<h3>What is Receptors and ligands?</h3>

Receptors and ligands come in many forms, but they all have one thing in common: they exist in closely aligned pairs, with a receptor recognizing only one (or a few) specific ligands, and a ligand binding to only one (or a few) target receptors. Binding of a ligand to a receptor changes its shape or activity, allowing it to transmit a signal or directly produce a change within the cell.

Plasma membrane receptors are membrane-anchored proteins that bind ligands on the outer surface of the cell. In this type of signaling, the ligand does not need to cross the plasma membrane. Therefore, many different types of molecules (including large, hydrophilic or "water-attracted" ones) can act as ligands.

Answer:

Anatomy supports the theory of evolution because some species share similar physical features that was present in a common ancestor.

An example of shared anatomy is sharks and dolphins. types of analogous structures, such as dolphins and sharks, do not prove species are related, but rather they support the Theory of Evolution by show how species do build up adaptations in order to fit into their environments

Molecular biology because DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.

in recent research is has been shown that the myoglobin and hemoglobin sequences for dozens of mammals, birds, reptiles, amphibians, fish, worms, and molluscs were related.

Structural similarities is when different animals share the same structural similarities. For example the skeletons of turtles, horses, humans, birds, and bats are very similar, despite their t different ways of life and the diversity of their environments.
