Physical and chemical changes may be similar because neither can change the number of atoms of each element that are present. 
<h3>What do you mean by Physical changes?</h3>
Physical changes may be defined as those changes which appeared physically like color, odor, texture, mass, and density. 
Chemical changes may lead to the formation of new chemicals with definite properties. It involves when the chemical identity of any substance may alter. 
Therefore, physical and chemical changes may be similar because neither can change the number of atoms of each element that are present.

Answer:
carrier protein
Explanation:
To resolve this, a specialized carrier protein called the glucose transporter will transfer glucose molecules into the cell to facilitate its inward diffusion. There are many other solutes that must undergo facilitated diffusion to move into a cell, such as amino acids, or to move out of a cell, such as wastes.
