Answer: motion energy : energy related to an object’s movement

thermal energy : energy of motion of particles in a substance

gravitational potential energy : energy related to height

chemical energy :stored energy related to positions of atoms within molecules

nuclear energy : energy released when a nucleus splits or combines

sound energy : energy generated by vibration of a string

Explanation: Motion energy is also called as kinetic energy and it is defined as the energy possessed by an object due to its motion.

Thermal energy is the measure of total kinetic energy of the particles in a substance. The greater the motion of particles, the higher is the temperature of the substance and thermal energy.

Potential energy is defined as the energy possessed by an object due to its position or height.

Chemical energy is the energy stored in the bonds of the molecules.

Nuclear energy is the energy possessed in the form of binding energy which held the protons and neutrons together in the nucleus.

Sound energy is the energy possessed by an object by virtue of vibration of matter.

During the Industrial Revolution, explain what caused the population of light-colored peppered moths to decrease and the populat

Mekhanik [1.2K]

Answer:

The light colored pepper moths were able to camouflage in the Birchwood trees unlike the darker ones. But when the industrial revolution came the amount of smoke from the factories made the Birchwood trees become darker in color do now the darker pepper moths were the ones who could camouflage while the white ones were easily eaten and killed. Since the darker colored moths were able to survive they had offspring who were also darker colored. Over time since mainly darker moths were produced it was common for pepper moths to be darker.

Which of the following are NOT functions of the spinal cord?

maksim [4K]

Answer:

Reflexes are not a function of the spinal cord.

Explanation:

The spinal cord is part of the central nervous system and is made up of neurons that go along it (from the end of the brain stem almost to the bottom of the spine).

The spinal cord receives incoming messages from the peripheral nervous system (including the sensory neurons) and pass on messages from the brain to efferent neurons (motor neurons at muscles).

The spinal cord contributes to learning as it passes on the info received from sensory neurons (that there is an obstacle in the path) to the brain and passes on the response from the brain to the muscles (to lift the foot up higher).

The spinal cord is essential for integration as it passes on sensory information to the brain to determine motor output.

Reflexes are when sensory information is quickly sent straight to motor neurons to move. It does not need to go to the brain (hence does not need to go to the spinal cord) for the reaction as it would be too slow. This is seen when someone who is paraplegic (paralysed at lower torso) can still move their leg in response to the doctor tapping their knee even when they cannot forcibly move their legs.

Therefore reflexes are not a function of the spinal cord.

Vikki [24]

Answer:

Yes.

Explanation:

Yes, the structures and functions of the central nervous system work to help prevent injuries with the help of bone. The main line of defense of central nervous system is the bones of the skull and spinal column, which create a hard physical barrier to injury. If these line of defense are not present for central nervous system so it has more chances to get injury so we can say that the structures and functions of the nervous system helps to prevent injuries.
