Answer:

The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.

Brain, spinal cord, retina, sensory neurons, ganglia, as well as nerves are the primary organ of the nervous system.

Nervous system: a network of organized cells with the specific purpose of carrying electrochemical inputs from sensory receptors to the location where a reaction takes place.

Every living thing has the capacity to recognize changes in both its own surroundings and outside it. Changes in the inner environment include those in the posture of the head and limbs as well as those in the internal organs, whereas changes in the exterior environment include those in light, temperature, sound, motion, as well as odor. The nervous system's organs include the brain, spinal cord, retina, sensory neurons, ganglia, as well as nerves.

Therefore,  brain, spinal cord, retina, sensory neurons, ganglia, as well as nerves are the primary organ of the nervous system.

Answer:

Troposphere, stratosphere, mesosphere, and thermosphere.

Explanation:

Troposphere - It is the lowest region of the atmosphere, extending from the earth's surface to a height of about 3.7–6.2 miles (6–10 km), which is the lower boundary of the stratosphere.

Stratosphere - It is the layer of the earth's atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth's surface (the lower boundary of the mesosphere).

Mesosphere - It is the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude.

Thermosphere - It is the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium. The thermosphere is characterized throughout by an increase in temperature with height.

Answer:

The First layer is the troposphere. The troposphere is what we live in. It creates weather for us. Second layer is the Stratosphere. You will find the ozone layer in it. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Life as we know it wouldn't be possible without this layer of protection. Third layer is Mesosphere. The Mesosphere is very important for earth's protection. The mesosphere burns up most meteors and asteroids before they are able to reach the earth's surface. Fourth layer is Thermosphere. The Thermosphere absorbs the sun radiation making it very hot.

Explanation:: I don't know if you include this one but the fifth layer is the Exosphere. Although the exosphere is the most distance layer of earth's atmosphere it is the layer that is the planet's first line of defense against the sun's rays. It is also the first layer to come into contact and protect the earth from meteors, asteroids, and cosmic rays.

Answer:

A mole of horses would be Avogadro number of horses (a lot actually !). Avogadro number is 6.023 x 10(23). A mole of H (hydrogen) atoms contains 6.023 x 10(23) H atoms. A mole of H2 molecules contains 6.023 x 10(23) H2 molecules or 2 moles of H atoms (since each molecules has 2 atoms).

Explanation:

Answer:

A mole (mol) is the amount of a substance that contains 6.02 × 10 23 representative particles of that substance. The mole is the SI unit for amount of a substance. Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 23 water molecules in a mole of water molecules.

Explanation:

Answer: 3.2x10^23

Explanation:

Start by finding the molar mass of aluminum.

Then turn  grams into moles by dividing grams of substance by molar mass. 1.4g÷26.98g

Then multiply that by 6.022x10^23 atoms. 0.0519x6.022x10^23

You can use dimensional analysis to solve this type of problem.

A loss of negatively-charged electrons corresponds to an increase in oxidation number, while a gain of electrons corresponds to a decrease in oxidation number. Therefore, the element or ion that is oxidized undergoes an increase in oxidation number.

Answer:

This molecule is AgN3

Explanation:

Answer:

AgN3

Explanation:

Mass of nitrogen N is given as 24.36 g

Molar mass of nitrogen N= 14 g/mol.

amount of substance in mol of N = mass/molar mass

=24.36 g/ 14 g/mol.

=1.74 mol.

Given mass of silver= 62,64 g.

Molar mass of silver Ag=107.87 g/mol

Number of mols=62.64 g ÷ 107.87 g/mol.

=0.58 mol.

Ratio of number of mol of N and number of mols of Ag = 1.74 mol / 0.58 mol

=3:1

Hence, empirical formula is AgN₃.

Answer:

When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.

Explanation:

BTW I GOT THE ANSWER FROM KRISTINA

The thermal energy of a system is the amount of heat energy in it.

One way to change thermal energy is by alter the system by introducing a new object to the system.

The thermal energy of a system is calculated using:

[tex]E = \frac 12 mc\theta[/tex]

Assume the mass of the system remains unchanged.

When an object is introduced to the system, the thermal energy becomes:

[tex]E_2 = \frac 12 mc(\theta + \alpha)[/tex]

Where:

[tex]\alpha \ne 0[/tex] --- the temperature of the object.

Expand:

[tex]E_2 = \frac 12 mc(\theta) + \frac 12 mc (\alpha)[/tex]

Substitute: [tex]E = \frac 12 mc\theta[/tex]

[tex]E_2 = E + \frac 12 mc (\alpha)[/tex]

This means that the thermal energy of the system will change by the thermal energy of the object that is being introduced to the system.

Hence, one way the thermal energy can be changed is to introduce a new object (or matter).

Answer:

higher temperature, more kinetic energy, more space between particles, higher volume

This is true because increase in temperature kinetic energy increase so molecules move apart and increase volume

Explanation:

Answer: It decreases because nonvolatile aluminum and chloride ions now occupy some of the volume of the system.

Explanation:

Vapor pressure of a liquid  is defined as the pressure exerted by the vapors  in equilibrium with the liquid/solution at a particular temperature.

So, when a non-volatile solute is added to a solvent then its molecules align at the surface of liquid. As a result, less number of solvent molecules will escape from the solution. Thus, there will be decrease in vapors and thus the vapor pressure decrease.

The relative lowering of vapor pressure is directly proportional to the amount of dissolved solute.
