1. Action potential reaches the axon terminal and depolarizes it.

2. Depolarization opens voltage-gated calcium channels, enabling influx of Ca into the neuron.

3. Calcium binds to specialized proteins on vesicles (containing pre-made acetylcholine) and triggers them to fuse with the neuron membrane at the synapse.

4. Exocytosis of acetylcholine into the synaptic cleft occurs.

5. Acetylcholine diffuses across the synapse and binds to nicotinic receptors on the end plate of the myocyte.

6. Activated nicotinic receptors, themselves ion channels, cause cation influx into the myocyte and generate an end plate potential. This eventually gives rise to the full depolarization within the myocyte that enables contraction.

dem82 [27]

Explanation:

During  PCR, we use two primers one is forward primer and the other one is reverse primer they match the  sequence of one one of the two complementary strands of the target DNA, they flank the target region (that the region which we has to be copied). if we add only one primer it copies only one strand of the DNA in multiple copies. Usually we call this as Asymmetric PCR.

Generally Primers are synthetic short stretch of oligonucleotides that are complementary to the target DNA. They act as a foundation for the amplification process of  DNA to form multiple copies

How does oct1 recognize the position on the dna molecule where it should bind?
Anastasy [175]
<span>OCT1 is a protein that hepatic which serves as a uptake transporter which is on the blood side of hepatocytes whose primary function is disposition of cationic drugs. OCT1 recognize the position on the DNA molecule by recognizing the specific sequence of bases as it has the binding motif.</span>

Below are three different scenarios for comparison. For each scenario, decide if it represents greater or less entropy and great
uranmaximum [27]

Answer:

Entropy is characterized as a level of irregularity or disorder in a system. More the disorder more is the Entropy. The greatest entropy is accomplished when the system is in equilibrium.  

In a similar manner, stability is legitimately relative to entropy. Therefore, more entropy, more is the stability and the other way around.

<u>S.No      Scenarios                Entropy                  Stability </u>

A               Glucose                    Less                   Less

           Carbon dioxide or water      More                   More

B        A messy room              more                    More

               A clean room                      Less                     Less
