Examine the words,
impulse, presynaptic cell, neurotransmitters, receptors, postsynaptic cell,
What idea can be described using all the words listed?

Answers

The synapse is the place where the electrical impulse is modulated, it begins with a chemical-electric discharge in the presynaptic cell and the postsynaptic cell has the receptors that receive and are activated by the neurotransmitter.

What is synapse?

It is the functional relationship of contact between the endings of nerve cells.

This communicative process between neurons begins with a chemical-electric discharge in the membrane of the emitting cell (presynaptic cell).

When said nerve impulse reaches the end of the axon, the neuron secretes a substance that lodges in the synaptic space between this transmitting neuron and the receiving neuron (postsynaptic cell), in turn, this neurotransmitter is responsible for exciting another neuron.

Therefore, we can conclude that the synapse is the place where the electrical impulse is modulated, it begins with a chemical-electric discharge in the presynaptic cell and the postsynaptic cell has the receptors that receive and are activated by the neurotransmitter.

Answers

The phenotype of the fish when both R and Bl are present will be Blue and Red while the genotype will be BR.

What is co-dominance?

Co-dominance in genetics is the condition in which alleles of a gene are both dominant in that when both are present in an organism, the organism will show the phenotype of both alleles.

Since the alleles B for blue coloring, and R for red coloring are both dominant, when both are present in the fish, the phenotypic coloring in the fish will be blue and red.

We can confirm that when a ribosome hits a stop codon, the translation process halts, which is the process by which the mRNA is read to produce a protein through the use of tRNA and aminoacyl-tRNA synthetase.

What are the distinct types of RNA?

The process of translation in order to produce a protein has many parts. The mRNA is the messenger RNA that holds the genetic code needed to create the protein, this is read by the ribosomes. These ribosomes use the aminoacyl-tRNA synthetase enzyme to attach the corresponding amino acids to the transfer RNA or tRNA and later to the protein itself.
