A point mutation or substitution is a genetic mutation where a single nucleotide base is changed, inserted or deleted from a sequence of DNA or RNA. Point mutations have a variety of effects on the downstream protein product—consequences that are moderately predictable based upon the specifics of the mutation.
Hope this helps
The type of solution in each beaker based on cell's reaction are :
- Isotonic solution : Normal reaction
- Hypotonic solution : The cell becomes turgid
- Hypertonic solution : The cell becomes deformed
<h3>Matching each solution to the cell reaction </h3>
When the red blood cell is placed in an isotonic solution the solvent flows in and out of the blood cell at the same rate, when the cell is placed in a hypotonic solution the solvent flows into the cell at a faster rate causing the cell to swell ( becomes turgid ) also when the cell is placed in a hypertonic reaction the cell becomes deformed becomes it loses more water than it absorbs.
Hence we can conclude that The type of solution in each beaker based on cell's reaction are : Isotonic solution : Normal reaction, Hypotonic solution : The cell becomes turgid, Hypertonic solution : The cell becomes deformed

The answer is B because:
Cell walls are made of cellulose and proteins (hence II).
Animal cells don't have cell walls (only cell membrane) but plant cells do so IV
They must be semipermeable since materials for example carbon dioxide and water for photosynthesis have to go into the cell <em>some</em> way.
It’s actually bacterial DNA
