Stomata are made up of two cells known as guard cells and an opening of stoma
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.

The answer would be A . stem cell research exploits fetuses and a mothers eggs because it is the only one that says something negative about stem cell reaserch, hope this helps :))
The properties of matter, The general properties of matter result from its relationship with mass and space. beacuse of its mass, all matter has interia and weight, if it is in a gravitational field.
Answer:
Processing and packaging of cellular materials prior to export
Explanation:
Our cells contain many different organelles. Every organelle has its own function, just like every organ in our bodies.
The Golgi apparatus is one of these organelles. It can be found in most eukaryotic cells. Its purpose is to transport, modify, and package proteins and lipids before they're delivered to other parts of the body. This is the function the organelle with smooth-sided channels Megan is observing would need to perform in order to be identified as the Golgi apparatus.
