The question is incomplete as it does not have the options which are:
- sacral plexus
- femoral plexus
- thoracic plexus
- lumbar plexus
Answer:
Sacral plexus
Explanation:
The spinal cord is considered an organ which is composed of the nervous tissues. The spinal cord passes through the vertebral column or foramen and based on these foramen is divided into 31 segments from which a bundle of nerves fiber exits.
The spinal cord is divided into the 5 lumbar and 5 sacral division in which the bundle of nerves which exit from the S1 to S4 which are also joined by the L4 and L5 are called the sacral plexus.
The sacral plexus is formed of nerves which exit from the spinal cord to the pelvis and the lower limb.
Thus, Sacral plexus
is correct.
Answer:
Explanation:
This is because once a Voltage Gated Sodium Channels closes up after depolarization, they can not be reopened.The transmission of action potential is such a way that they are propagated one after the other in a forward direction, and never backwards. Thus once a sodium channel depolarizes,it closes up, to under go a shot rest.No matter the strength of the next stimulus it will not open. Then the channel ahead of it opens to depolarise to conduct action potential, this again after shut opening closes up for the channel ahead to open. This short period of rest when the sodium channels closes up is called refractive period. However after sometime of rest the rested sodium channels open, from the inactivated stage to conduct action potential.
D. He has an aerator that pumps bubbles into the tank
The fructose 1-phosphate pathway can deplete intracellular phosphate/ ATP.
Explanation:
Fructose 1-phosphate is a derivative of fructose. For understanding in better way fructose metabolism has three enzymes. Fructose- bisphosphate aldolase B, fructokinase and Adenosine triphosphate. These all are present in liver and kidney of human as well rat. In liver rapidly fructose is change to fructose 1 through fructokinase.
After it is converted into trioses dihydroxyacetone phosphate as well as glyceraldehyde through aldolase. With glucose metabolism Fructose get synergistic effect
Answer: Low oxygen content.
Explanation:
There are many dangers to the survival of fish in shallow water that depend on the properties of water.
1. The oxygen content drops during the winter and also in hot weather. Fish cannot survive without enough oxygen in the water.
2. High evaporation rates can drain the pond.
3. Fortunately, water has a high thermal mass, so overheating the water to the boiling point is not an issue.
Of the three reasons given, lack of oxygen is the most critical.
