Answer:
The answer D
Explanation:
The answer is in the question.
Action potential is a mechanism of transfer of ions across the plasma membrane down their elctrochemical gradient. Action potential is regenerated by the influx of ions such as sodium in case of voltage gated sodium channels. The voltage gated channels can be either open or closed depending on the action potential. Depolarization of membrane leads to the opening of these channels that allow the sodium ions to enter the cell down their electrochemical gradient. The threshold of action potential is reached when the entry of sodium ions out reach the exit of potassium ions from the cell. This leads to the generation of action potential.
Answer: create proteins by bonding together amino acids.
Explanation:
Translation can be defined as the process in which the messenger RNA is decoded in the ribosome that is outside the nucleus. This is done to produce the specific chain of amino acid to produce polypeptide chain. The polypeptide chain get folded to produce protein this protein is responsible for performing functions in the cell. The genetic code determines the relation in between the amino acid sequence and base pairs in the gene.
The correct answer is Certain flightless beetles have wings. Their wings are an example of an adapted structure.
These beetles have adapted structure in them and it is inherited from their ancestor's gene pool. as the time passes by the flightless beetles don't have wings as it was not needed but later become adopted due to environmental needs.
<h3>What is adapted structure?</h3>
Thick, hardened beetle wings, called elytra, cover the whole body and it has covered whole body of beetles. The adaptive features are inherited from their ancestor's gene pool.
Hence concluded that adapted structures in flightless beetles have wings. Their wings are an example.
