Dendrites -> Soma -> Axon -> Terminal buttons
is the actual order that information follows as it travels through a neuron
What is neuron?Neurons are messengers of information. Between various brain regions and between the brain and the rest of the nervous system, information is transmitted using electrical impulses and chemical signals. Without the action of neurons and their supporting cells, the glial cells known as oligodendrocytes and astrocytes, humans would not be able to think, feel, or act.
A cell body, an axon, and two extensions called a dendrite make up the three basic components of a neuron. There is a nucleus inside the cell body that regulates the cell's functions and houses its genetic material. The axon, which resembles a long tail, delivers signals from the cell. Dendrites serve as the cell's messengers and resemble the tree's branches.

A student wonders whether a piece of jewelry is made of pure silver. she determines that its mass is 3.17 g. then she drops it into a 10 ml graduated cylinder partially filled with water, and determines that its volume is 0.3 ml. could the jewelry be made of pure silver?
No, the jewelry, could not be made of pure silver.
State characteristics properties of silver.The characteristics of pure silver include being almost white, shiny, soft, ductile, malleable, and a superb conductor of both heat and electricity. Although it is not a chemically active metal, heated concentrated sulfuric acid and nitric acid both attack it and cause nitrate to form. Silver is one of the so-called precious metals, along with gold and the metals from the platinum group. Silver has been used for many years to make coins, ornaments, and jewelry due to its relative rarity, dazzling white color, malleability, ductility, and resistance to air oxidation. Silver is also a soft, malleable, highly ductile, and shiny metal. Despite having the highest electrical conductivity of any metal, its exorbitant cost prevents it from being widely used for electrical purposes. Silver is not a metal that reacts chemically.

The specific heat of ethanol is 2.46 J/gºC. Find the heat energy required to raise the
temperature
of 193 g of ethanol from 19°C to 35°C
The correct answer is 7596.5 Joules of heat energy is required to raise the temperature of 193 g of ethanol from 19°C to 35°C.
The amount of heat required is calculated as follows:
Q = mC∆T
m = mass =193g of ethanol
C = specific heat = 2.46J/g°C
∆T = T f-Ti = 35-19°C = 16°C
Q = 193g *2.46J/g°C *16°C
Q = 7596.5 J
We are interested in the value of Q, which is the quantity of heat. We would use the equation Q = mCΔT to do so. mass and specific heat are known; using the initial and final temperatures, the T can be calculated. Once we know three of the four quantities in the relevant equation, we can substitute and solve for Q. The amount of heat energy required to raise the temperature of a substance is referred to as its specific heat energy.

Taking into account the definition of density, the volume of cyclohexane should be 23.13 mL.
Definition of densityDensity is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space and allows us to measure the amount of mass in a certain volume of a substance.
The expression for the calculation of density is:
density= mass÷ volume
Volume of cyclohexaneIn this case, you know that:
Density= 0.7781 g/mLMass= 18 gReplacing in the definition of density:
0.7781 g/mL= 18 g÷ volume
Solving:
0.7781 g/mL ×volume= 18 g

among the three named compounds, predict which one has the highest viscosity at 25°c. ethane pentane decane
Decane has the highest viscosity at 25°C.
The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress.
Viscosity depends on intermolecular interactions and molar mass of the substance.
Ethane, pentane and decane are acyclic saturated hydrocarbons (alkanes).
At 25°C, ethane (C₂H₆) is in gaseous state of matter. Its molecular mass is the smallest of these three molecules, so it has lowest viscosity.
Decane (C₁₀H₂₂) and pentane (C₅H₁₂) are liquids at 25°C, but decane has greater molecular mass, therefore the highest viscosity.
M(C₂H₆) = 30 g/mol; molar mass of an ethene
M(C₁₀H₂₂) = 72 g/mol; molar mass of pentane
M(C₅H₁₂) = 144 g/mol; molar mass of decane
