Answer:
<u> Neuromuscular Junction -</u> It is a chemical synapse formed by the contact between a motor neuron and a muscle fiber.
<u>Function- </u>As the motor neuron are <em>able to transmit the required signals</em> to the muscle fiber, which causes the muscle contraction.
Explanation:
<u>Steps in neuromuscular transmission:</u>
- calcium entry into the presynaptic terminus.
- diffusion of Ach across cleft.
- combination of Ach with post-synaptic receptors and Ach breakdown via esterase.
- opening of Na + /K + channels (cation channels).
- postsynaptic membrane depolarization (EPP).
Answer:
bound to oxyheamoglobin
Explanation:.
Oxyheamoglobin is formed from the reaction of oxygen with haemoglobin.it is the oxygen loaded form of haemoglobin for delivery of oxygen to needed remote areas of the body.
.Hb + 4O2 ⇒ HbO8
haemoglobin oxygen oxyhaemoglobin
Haemoglobin is a protein molecule that binds with oxygen. It has high affinity for oxygen with its four haem groups. Each haem group has binding iron.(Fe). When it is binds with oxygen it is bright red, and turns purple when it unloaded oxygen at target point.
It has no association with carbondioixde transports except oxygen transport
.
Carbon dioxide, is transported as the listed three options(b,c,d) in the questions. Therefore bound to oxyheamoglobin is wrong, and it is the correct answer

Answer:
Use a step wise process
Explanation:
In order to find the presence of the recombinant protein:
- Culture the cells that you believe harbors the plasmid for the recombination protein (+) and also cells that do not (-). This is your control.
- Extract the plasmid from both strains.
- Observe the plasmid map and the area of your insert. Use this to select the restriction enzymes at the beginning and the end of the YFG gene. You can also use a restriction site inside the gene but not in the plasmid for better control.
- Perform the restriction enzyme digest on both (+) and (-) according to your protocol and separate using gel electrophoresis.
- Observe the separate bands that you see. In the (+) there should be a band that is the size of your insert and a larger band that is the size of your plasmid control band and in the (-) there should be a single band that is the size of the plasmid but non the size of the insert.
