A chemical change is when atoms exchange electrons to form new chemicals/different arrangements of bound atoms. A physical change is simply any change that does not alter the type of molecules present.
Answer:
The characteristic that is not a function of the receptors is to receive glucose molecules.
Explanation:
The receptors are structures made up of proteins or glycoproteins whose function is to <u>receive specific signals</u>, which determine intracellular changes and promote an effect or action.
Most of the receptors are located on the surface of the cells, serve for cell recognition and are capable of receiving stimuli from neurotransmitters and hormones.
Glucose is a biomolecule that does not constitute a stimulus or possess a specific receptor and enters the cell with the use of a specific transporter.
Chromatin
is composed of a DNA and a protein. The DNA is a double helix in the cell
nucleus packaged by histones, a special type of protein. Together they form the
chromatin with a basic structural unit called nucleosome. The chromatin's functions are:
a. to
package DNA into smaller volumes to fit in the cell.
b. to
allow mitosis by reinforcing the DNA macromolecule
c. to
prevent damaging of the DNA
<span>d.to
control gene expression and DNA replication</span>
Traits usually result in sexual selection.
