In the depolarization step of action potential where the membrane resting potential is reversed by the rush of sodium ions into a neuron.
A membrane potential shift from -70mV to +30mV for a limited period of time is known as an action potential.
The moving action potential has three stages:
1) The depolarization step, where sodium ions rush into a neuron and reverse the membrane resting potential; and
2) repolarization, which is a mechanism that restores the resting voltage of the membrane and the ionic concentration in the cell, is caused by the closure of the voltage-gated sodium channels and the opening of the potassium channels.
3) Hyperpolarization, when excessive potassium ion efflux occurs as a result of some open potassium channels increasing potassium permeability and causing a drop in the membrane potential.
4) The action potential, which is a transient reversal of membrane potential that travels through the axon, comprises three phases that are described above.

I don’t know really tbh sorry
Answer:
the cell wall which is the cell membrane
Explanation:
the cell membrane gives the cell its shape and it protects the bacterial cell from the environment.
Answer:
U-A-C-G-G-A-U-G-C--C-C-C-C-G-G-U
Explanation:
The mRNA (messenger RNA) is produced via the process of TRANSCRIPTION, which is the first stage of gene expression in living cells. The mRNA sequence formed is further read in the ribosomes in a group of three nucleotides called CODONS. This reading is done by another type of RNA called transfer RNA (tRNA).
The tRNA uses a set of three nucleotide bases that are complementary to that of the mRNA codons called ANTICODON. The anticodons are complementary to the mRNA codon i.e. A on the mRNA sequence will be read and recognized by U on the tRNA anticodon.
Hence, given the mRNA sequence: A-U-G-C-C-U-A-C-G-G-G-G-G-C-C-A, the tRNA anticodons that will read this sequence will be: U-A-C-G-G-A-U-G-C--C-C-C-C-G-G-U
