the physical basis of memory is a pathway through the brain called a memory trace, in which new synapses have formed or existing synapses have been modified to make transmission easier.

Answers

Answer 1

True, New neural networks must be formed in the brain for learning and memory to take place. Synaptic plasticity at excitatory synapses, which connect neurons into networks, is a crucial mechanism behind this process.

Theoretically, memories are physically preserved in the brain as "engrams," or "memory traces," in the brain. It is still up for debate whether memory is actually stored biophysically or biochemically. The consensus, however, is that memory doesn't seem to be concentrated in just one part of the brain, but rather tends to be distributed throughout numerous.

A synapse's filtering properties can be changed by varying the initial release probability. The most frequent cause of this is the release of neuromodulators, which via activating presynaptic receptors decrease the likelihood of release.

The synaptogenesis process is one method your brain can heal itself. The creation of new synapses in the brain is known as synaptogenesis. Synapses serve as the interconnections between your brain's 100 billion cells.

Answer:

Glaciers.

A glacier is a huge mass of ice that moves very slowly downhill along the landscape.

Glaciers form in high latitudes near Earth's poles and at high altitudes, They form due to the accumulation (piling up) and compaction (packing down) of snow.As the glaciers expand, due to their accumulating weight of snow and ice they crush and abrade and scour surfaces such as rocks and bedrock. The resulting erosional landforms include striations, cirques, glacial horns, arêtes, trim lines, U-shaped valleys, roches moutonnées, overdeepenings and hanging valleys.

The correct answer is c. parasitism. In a parasitic relationship, one organism (the parasite) benefits by exploiting another organism (the host) for resources or shelter, while the host is harmed or negatively affected.

The parasite may cause disease, weaken the host, or even cause death. Commensalism is a type of relationship in which one organism benefits while the other is neither helped nor harmed. Symbiosis is a general term for any long-term close interaction between two different species, and it can refer to any type of relationship, including parasitism, commensalism, or mutualism. Mutualism is a type of symbiosis in which both species benefit from the interaction. Therefore, the answer is c. parasitism.

the intense visible light which comes from arc welding is a hazard to which part of your body?

Answers

The arcs and flames used for welding produce a lot of ultraviolet, infrared, and visible radiation. Similar to ultraviolet rays in sunlight, UV rays from welding arcs can burn unprotected skin.

This danger applies to both UV rays that are directly inhaled and those that are reflected off of metal, walls, and ceilings. UV rays can be deflected to a lesser extent using particular surface treatments and paint colors.

Skin cancer can be brought on by prolonged UV radiation exposure. Visible light and infrared radiation typically have very little impact on the skin. Due to its extreme brightness, visible light from welding operations might overwhelm the eye's iris' capacity to close quickly enough to reduce the amount of light that reaches the retina.

for each listed in the table, describe its role in cellular respiration. are they substrates or products? what is their main function?

Answers

1. Glucose: Glucose is a substrate that is broken down in cellular respiration to release energy. During glycolysis, glucose molecules are converted into pyruvate molecules, releasing energy in the form of ATP.

This energy is used to fuel other metabolic processes in the cell, such as the citric acid cycle. The pyruvate molecules from glycolysis are then further broken down in the citric acid cycle, releasing more energy in the form of ATP.

2. Oxygen: Oxygen is required for cellular respiration to take place. During cellular respiration, glucose is broken down in the presence of oxygen, releasing energy in the form of ATP. Oxygen is also used as the final electron acceptor in the electron transport chain, which generates a large amount of ATP.

3. Carbon Dioxide: Carbon dioxide is a product of cellular respiration, produced when glucose is broken down. During glycolysis and the citric acid cycle, carbon dioxide is released as a by-product of the breakdown of glucose. In the electron transport chain, the electrons that are transferred to oxygen produce carbon dioxide.

4. Water: Water is another product of cellular respiration, produced when oxygen is used as the final electron acceptor. During the electron transport chain, electrons are transferred to oxygen molecules, producing water molecules as a by-product. Water is also produced when glucose is broken down in glycolysis and the citric acid cycle.

2 "When experiencing the pain, nausea is often present."
3 "The pain may switch to the anterior side of your head."
4 "The pain experienced in cluster headaches is unilateral."

Answers

"The pain experienced in cluster headaches is unilateral." Cluster headaches, or migrainous neuralgia, is an uncommon type of headache. They occur in groups, or clusters, and the pain is described as sharp and severe.

The pain typically centers around one eye or one side of the face, and it may be accompanied by tearing of the eye, runny nose, and sweating on one side of the face. The pain experienced in cluster headaches is unilateral, meaning it occurs on one side of the head. The pain is usually focused around one eye, but it can spread to other parts of the face, including the temples and the forehead. Cluster headaches usually last between 15 minutes and 3 hours, and they can occur several times a day, sometimes for weeks or months at a time.

The nurse would include more than 100 words when teaching the clinical manifestations of cluster headaches to a group. The nurse would explain that cluster headaches are different from other types of headaches because they are characterized by intense, stabbing pain that occurs on one side of the head.
