Answer:
What can be noticed about the ligands and their receptor is that the configuration of both coincide, as a key would with its lock, which demonstrates the specificity of a receptor by its ligand.
Explanation:
A <u>ligand</u> corresponds to a molecule considered a signal or a messenger, while the <u>receptor</u> is a protein on the cell surface, with the capacity to accept a ligand.
Ligands and receptors constitute pairs that complement each other, so that <u>each receptor can bind to a specific ligand</u>, similar to what happens with a key and a lock.
Once the ligand-receptor complex is formed, changes occur inside the cell, which define a certain effect.
B
water is a miscible liquid which mean other liquid can dissolve in it.Also aqueous solution can dissolve in it.
Fixation answer : hope this helps
Since the cell is in a shoebox, we can assume this cell is a plant cell. the balloon most likely represents the vacuole, which is the largest organelle in the plant cell. the marbles could represent ribosomes, but ribosomes aren’t the only round organelle so i’m not sure about that one.
