Which statement describes a similarity between

all enzymes, antibodies, and hormones?

(1) Their chemical structure is critical to their

ability to function.

(2) Their ability to replicate identical copies

ensures continuation of the species.

(3) They work better at 100°C than 37°C.

(4) They are made by and carried by the blood.

Verified Answer :

Control - Chemicals produced in the endocrine glands (HORMONES) and chemicals produced by nerve cells are primarily responsible for communication between cells.

Answer:

(1) Their chemical structure is critical to their  ability to function.

Explanation:

All enzymes, antibodies, and hormones have a similarity like they all have a particular and unique chemical structure which is critical to their ability to function. If they lose their shape then they will lose their function because in enzyme there are active site which have a particular shape in which substrate will bind.

Each antibody bind to specific antigen according to the chemical shape they have and hormone also binds to their receptor so they should have that shape that can fit into the receptor.
