Point mutations can show three different types of effects:
- Base substitutions can be silent mutations in which the changed codons correspond to the same amino acid.
- Base substitutions can be missense mutations where the changed codon corresponds to a different amino acid.
- Base substitutions can be nonsense mutations in which the altered codon corresponds to the stop signal.
<h3>What are point mutations?</h3>
Point mutations are changes to the N base of DNA or RNA. Point mutations are common, but their effects can be mitigated by gene recovery mechanisms.
The cause of this point mutation is due to 4 factors:
- Errors during DNA replication by mutagens.
- Breaking of oxygen-phosphate bonds.
- Substitution of base pairs.
- Changes in the number of bases.

<span>This indicates that energy consumption could have fluctuated. </span>
Answer:
The correct answer is it will be pushed away from the source of the electric field.
Explanation:
An electric field contain two electrodes positive charged electrode or anode and negative charged electrode or cathode.These 2 electrodes cathode and anode are connected by an electric wire to a battery and this whole system is linked to a electric system.
When electric current is applied oxidation reaction occur in anode and reduction reaction occur in cathode.
Now according to the question if a positively charged object is placed within a positive electric field then pushes the positively charged object away from itself because we all know that positively charged ion reflect another positively charged ion.
Answer: c) A High-Pressure System
Explanation: A high pressure system is a whirling mass of cool, dry air that generally brings fair weather and light winds.
Of course not! There's lots of ways materials can enter. It also depends on the cell; whether it has cell wall and cell membrane or only cell membrane.
Besides diffusion, there's also osmosis and active transport.
If the cell has only cell membrane, it means it's partially permeable, which means osmosis can happen.
