Answer:
Option C, open chemically gated sodium ion channels.
Explanation:
The nicotinic receptors are present on the muscle cell membrane. These receptors belong to the class of cholinergic receptor which binds to the acetylcholine and opens the gated channel to allow transfusion of cation through it. These actions of the receptors are stimulated by the neurotransmitter. Nicotinic receptors are very fast at acting and hence are more prevalent at the neuromuscular junction.
Hence, option C is correct
As the two tectonic plates shift, fissures periodically form in the crust that allow molten rock from underground to surface as lava, creating Iceland's many volcanoes.
Answer:
Genes
Explanation:
A gene is a hereditary unit that parents pass to their offspring, and they will determine the kind of characteristics the baby will have like will they be short or tall, have blue or brown eyes, will they have blond or black hair. The offspring will get different genes from its parents and it will therefore be genetically unique. Some traits or characteristics may be dominant over others. For example the mother has brown eyes and the father has blue eyes, so in this case eye color has two alleles (an allele is a specific version of a gene, in this case allele for blue eye color and an allele for brown eye color), and now the baby is born with brown eyes, so brown eye color was dominant over the blue eye color so that is the trait that we will see in the baby. The genetic is a lot more complex but this is a more simplified explanation of how offspring express certain traits from their parents.
