How old it is compared to another specimen in relation.
The correct codes are 63267 and 69990.
The codes are given based on the lesion if it is intradural or extradural. In our case here it is extradural cystic structure so that is why it ranges between 63265 to 63268.
We also divide the section of spine depending on where the lesion is being located. Code 63267 describes laminectomy which has evacuation of intraspinal lesion which is found in the lumbar spine.
69990 code documents the use of microscope.
Answer:
The correct answer is - The neuron's intracellular charge must get more positive to meet a certain thresh hold in order to depolarize. If the neuron does not hit that threshold, then the neuron will not fire
Explanation:
In neuroscience, the depolarization of neurons shows the all or none law which is also called as all or nothing response. It states that all action potentials have the same size and the potential or strength of a nerve cell does not depend on the stimulus strength as all are the same size.
If a stimulus reaches a particular threshold cell or fiber will fire so either it will fire or not cross the threshold this is all or nothing response or law and depolarization is an example of it.
B. Chloroplasts perform photosynthesis, which converts light into sugar, which is food (energy). Then, the organelle mitochondria coverts that energy into a more usable form of energy by the cell, in a process called cellular respiration.
The answer is 1.2 m³
1 L = 1 dm³
1,200 L = 1,200 dm³
1 dm³ = 0.001 m³
1,200 dm³ = 1,200 * 0.001 m³ = 1.2 m³
