Answer:
"Action potential is a rapid rise and subsequent fall in voltage or membrane potential across a cellular membrane with a characteristic pattern."
It is the mode through which a neuron transports electrical signals.
Explanation:
- Option - (a) is the best choice to choose from,
- <u>The refractory period :</u>
A second action potential cannot occur until the membrane has recovered or reestablished, this is the refractory period. The absolute refractory period coincides with inactivation of voltage-gated sodium channels which makes it impossible to generate another nerve impulse.
Answer:
1. Substitution
2. Insertion and deletion
3. Amino acids can have more than one codon that signals for it. Due to this, some substitutions don’t affect the protein at all.
Explanation:
1. Substitution sometimes isn’t as impactful. It can result in the same amino acid to be signaled as the original one since amino acids can have more than one codon signaling for it.
2. Insertion and deletion are also known as frameshift mutations. This is because they shift the codon spots by adding or deleting a nucleotide.
A heterozygous cat has a genotype Hh
A hairless cat has a genotype hh
When crossed, the results could be any of the following:
Hh (with hair)
hh (hairless)
There is a 50:50 chance or 1: 1 ratio that the offspring will have hair.
