The correct answer is: B) nodes of Ranvier.
Schwann cells are non-neural cells that are part of the peripheral nervous system with supportive function for neurons. In myelinated axons, Schwann cells form the myelin sheath that is not continuous. The tiny gaps between adjacent Schwann cells are called nodes of Ranvier.
Nodes of Ranvier are the spots where the axolemma (the cell membrane of an axon) is exposed to the extracellular space. Because of the presence of nodes, nerve conduction in myelinated axons is referred to as saltatory conduction.
In order to see precise cells, living cells are better to observe to get the correct information while dead cells do not do anything and you can't really get information out of it
Answer:
An Overview of Geothermal Pros and Cons:
Pros Cons
This energy source is more environmentally friendly than conventional fuel sources. The largest single disadvantage of geothermal energy is that it is location specific.
A source of renewable energy. Gases are released into the atmosphere during digging.
The number of exploitable geothermal resources will increase with ongoing research and development in the industry. Geothermal energy runs the risk of triggering earthquakes.
A sustainable source of energy as its always available unlike wind and solar. Expensive resource to tap into, with high upfront costs ranging from around $2-$7 million for a plant with a 1 megawatt capacity.
A reliable source as its easier to predict the power output from a geothermal plant with a high degree of accuracy. Energy fluid needs to be pumped back into the underground reservoirs faster than it is depleted. Management is required to maintain sustainability.
No fuel is required.
Increase in exploration meaning that new technologies are being created to improve the energy process.
Pollution levels are much lower compared to fossil fuels.
Explanation:
Energy is transfered from a molecule of sugar to atp by cellular respiration
