Answer:
Gram negative bacteria don't retain purple color as they contain thin cell wall which is composed of peptidoglycans present between inner cytoplasmic cell membrane and bacterial outer membrane.
Explanation:
They contain some characters like-
- The outer membrane is important as it protects them from antibiotics,detergents that damages the peptidoglycans of cell membrane.
- The outer membrane is composed of lipopolysaccharide that secrets lipid A component which causes toxic reaction.
- This toxic reaction creates different health hazards like high fever,increase respiratory rate,low blood pressure etc.
- Braun's lipoprotein present between outer membrane and peptidoglycans by a covalent bond.
I would say it dose because rust lets out a tun of chemicals

Protons and neutrons are energy particles found in the nucleus of atoms.
Explanation:
The forces that hold the protons and neutrons together in the nucleus are called strong nuclear forces. These forces are attractive over short distances and repulsive over long distances. This is why protons that are positively charged are held together in the nucleus despite their repulsive tendencies. However, as the nucleus gets larger because of the larger number of protons and neutrons in the nucleus, the distance with which the string nuclear forces are attractive is surpassed.
The binding energy in the nucleus will, therefore, be surpassed by the repulsive forces of strong nuclear forces over long distances causing the atomic nucleus to lose some neutrons.
