As Maria continued to read about common conditions of the nervous system, she realized there was a category of cells called neuroglia that allowed neurons and the nervous system as a whole to properly function. Some of her symptoms seemed to fit with a condition that resulted from a slow destruction of some of these cells.
Correctly match the cell type with the sentence that describes it.
_______are the neuroglia, which help to regulate the reuptake of neurotransmitters from neural tissue.
Cell bodies of unipolar neurons are insulated from adjacent cell bodies by .
The ventricles of the brain are lined with _______, which form an epithelial layer that is permeable to cerebrospinal fluid.
The macrophages of the Central Nervous System, which function to remove foreign microorganisms, are called_______ .

Answer:
Astrocytes are the neuroglia, which help to regulate the reuptake of neurotransmitters from neural tissue.
Cell bodies of unipolar neurons are insulated from adjacent cell bodies by satellite cells.
The ventricles of the brain are lined with ependymal cells, which form an epithelial layer that is permeable to cerebrospinal fluid.
The macrophages of the Central Nervous System, which function to remove foreign microorganisms, are called microglia.
The myelin sheath of the Central Nervous System is formed by oligodendrocytes.
Axons of unipolar neurons are insulated by Schwann cells, which increase the speed of the electrical impulse.
Explanation:
The neuroglia cells are a group of specialized cells that are in the Central and Peripheral Nervous System.
Astrocytes are star-shaped cells that maintain homeostasis in the nervous tissue. They also are part of the blood-brain barrier controlling what can enter the brain and whatnot.
Satellite cells are in the Peripheric Nervous System. They are around neurons and provide nutrients and insulation to neurons.
Ependymal cells are in the Central Nervous System. They line the ventricles and spinal cord's central canal. They are the ones that help in the production and circulation of the cerebrospinal fluid (CSF). They are part of the blood-cerebrospinal fluid barrier, keeping the cerebrospinal fluid clean, and they also absorb the CSF.
The microglia are the macrophages of the Central Nervous System. They phagocytize any pathogen that they detect in the CNS, protecting the neurons.
The myelin sheath is formed by the oligodendrocytes in the CNS and by the Schwann cells in the PNS. Their function is to insulate the axons so that the electrical impulse can travel through them.

Answer:
Well think of it like this a tsunami can destroy cities killing hundreds maybe even thousands they can get as tall as 150+ feet and not to mention leave millions of dollars in damage.
Explanation:
Answer:
Explanation: Hey, so when they hit land, most tsunamis are less than 3 meters high, but in extreme cases they can exceed 30 meters near their source. A tsunami can hit shore as a rapidly rising tide or wall of turbulent water, and a large tsunami can flood many meter of land. Hope it helps x.
As we learned plasma proteins Fibrinogen and Prothrombin are both needed for coagulation. However, there is much more fibrinogen (4% of plasma proteins) compared to prothrombin (present in only small traces). Applying your knowledge of enzymes and clotting cascade, explain the difference in their abundance.
Answer:
Fibrinogen is present in much higher amounts than what is required for coagulation while Prothrombin is present in low amounts in order to prevent excess conversion to thrombin during blood clotting
Explanation:
Fibrinogen is functional for processes such as inflammation, atherogenesis and not for blood Coagulation and they are required to form Fibrin fibers which will in turn form blood clots. Fibrinogen is present in much higher amounts than what is required for coagulation while
Prothrombin is present in low amounts in order to prevent excess conversion to thrombin during blood clotting. and this is because increased concentrations of thrombin will lead to an extensive intravascular thrombosis
Compare and contrast disorganized schizophrenia and paranoid schizophrenia.
Answer:
The paranoid subtype is characterized by the presence of hallucinations and delusions. In the disorganized one appears a behavioral disorganization and of the thought and language as well as an inappropriate affect. These patients tend to have an earlier onset, a worse prognosis, and a greater number of neurocognitive alterations.
Explanation:
Paranoid schizophrenics are characterized by sharp delusions, especially persecution ideas of grandeur, often with a corresponding aggressive reaction in response to the alleged persecution. There may be hallucinations of various kinds, to which patients react consecutively, but later, as deterioration occurs, apathy and indifference appear. Hallucinations are common. On the other hand, disorganized schizophrenia is another form of schizophrenia that is characterized by disorganization of speech, that is, the language is rambling and incoherent, the behavior is unpredictable, inappropriate and incongruous.
Answer:
The paranoid subtype is characterized by the presence of hallucinations and delusions. In the disorganized one appears a behavioral disorganization and of the thought and language as well as an inappropriate affect. These patients tend to have an earlier onset, a worse prognosis, and a greater number of neurocognitive alterations.

The reactions of glycolysis that are shared with those in gluconeogenesis (ie use the same enzymes) are those that: Are substrate level phosphorylations Are irreversible. Are regulated steps. Operate close to equilibrium. g
Answer:
The reactions of glycolysis that are shared with those in gluconeogenesis (ie use the same enzymes) are those that Are regulated steps.
Explanation:
Glycolisis and gluconeogenesis are two mechanisms related to the carbohydrates metabolism. Sometimes they are considered reverse processes. However, they are different because of the control points they have where reactions are irreversible.
Glycolisis and gluconeogenesis share 7 common reactions, that are reversible. Thses reactions are coordinated and regulated by F-2 and 6-BP as the answer to the hormonal action.
Glycolisis happens in the muscle, while Gluconeogenesis happens in the liver. Together they form the "Cori Cycle".

What type of conservation will result in the greatest reduction in the burning of fossil fuels?
Answer:
Conservation of air.
Explanation:
Conservation of air will result due to greatest decrease in the burning of fossil fuels because fossil fuels greatly damage the air. The burning of fossil fuels produces carbondioxide gas in large amount that can be released in the atmosphere. This increase in carbondioxide gas in the air causes pollution that leads to global warming as well as health problems in humans. So we can conclude that decrease the use of fossil fuel leads to conservation of air.

6. Looking at the chemical equation for anaerobic respiration in the Introduction portion
of this lab, what product of cellular respiration was the gas in the balloon?
NEED HELP
Answer:
Because carbon dioxide is a component of your breath, and when you exhale, you release it.
Carbon dioxide
How do you blow up a balloon? You might know that carbon dioxide is what we exhale into a balloon, but where does it come from? Carbon dioxide is a waste product from a process called cellular respiration, which uses oxygen and sugar to make energy and carbon dioxide.
What is carbon dioxide?Carbon dioxide (chemical formula CO2) is a chemical compound occurring as a colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. The current concentration is about 0.04% (417 ppm) by volume, having risen from pre-industrial levels of 280 ppm. In water it forms an acidic solution due to the formation of carbonic acid (H2CO3). Natural sources include volcanoes, forest fires, hot springs, geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, ice caps, glaciers and seawater. It is present in deposits of petroleum and natural gas. Carbon dioxide has a sharp and acidic odor and generates the taste of soda water in the mouth, but at normally encountered concentrations it is odorless.
As the source of available carbon in the carbon cycle, atmospheric carbon dioxide is the primary carbon source for life on Earth and its concentration in Earth's pre-industrial atmosphere since late in the Precambrian has been regulated by photosynthetic organisms and geological phenomena. Plants, algae and cyanobacteria use energy from sunlight to synthesize carbohydrates from carbon dioxide and water in a process called photosynthesis, which produces oxygen as a waste product
