Why does a healthy cardiovascular system help prevent neurological diseases and disorders?because arteries provide the needed blood flow to the brain and neuronsbecause memory loss is prevented when the heart pumps efficientlybecause the heart and spinal cord are close together in the bodybecause exercise is critical for proper breathing, which can prevent seizures

QUESTION POSTED AT 26/03/2020 - 01:04 PM

Answered by admin AT 26/03/2020 - 01:04 PM

Ans.

Cardiovascular system is composed of blood, blood vessels, and heart that transports blood throughout the body. The cardiovascular system also provides blood to the neurons and brain cells, and prevents memory loss.

Various researches have found that heart problems can lead to various neurodegenerative disorders. For example, vascular dementia is a type of memory loss, which occurs due to problem in normal blood flow to the brain cells.

Thus, the correct answer is option). 'because memory loss is prevented when the heart pumps efficiently.'

Which source of energy do refrigeration systems and heat pumps have in common? air ground water sunlight

Answer:

A) Air

Explanation:

In refrigerator system the compressor will compress the gas at high pressure so that its temperature is too small and if is passed through the air inside the refrigerator.

When this low temperature gas is passed through the air inside the refrigerator then it will extract the heat from the space or air at high temperature and hence it is the source of energy inside the refrigerator.

Heat pumps are used in in cold atmosphere where we require thermal energy to keep the temperature high. Here compressor will work on the gas so that it will absorb the heat from surrounding air and release it to the room or inside space.

So here in both cases the source of energy here is Air which will give heat to the system.

Answer:

According to scientists, the solar system formed from a rotating disk of dust and gases

Explanation:

According to the scientists, the sun and the Solar System originated 4.5 billion years ago from a cloud of gas and dust that revolved around itself. Under the action of its own weight, this cloud flattened into a disk, at the center of which formed the sun. Inside this disk, a process of agglomeration of solid materials began, which, when they collided with one another, gave rise to ever larger bodies, the other planets.

NEED HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!! A scientist measures the rate of a reaction between two liquids. Then he performs the reaction again, adding solid manganese. The reaction takes place more quickly the second time. The mass of the manganese decreased by 0.45 grams during the reaction. He claims that the manganese acted as a catalyst because it sped up the reaction. Explain what is wrong with the scientists' reasoning.

A catalyst is a substance that alters the reaction and doesn't involve in the reaction.So if the Manganese was a catalyst the mass would not have decreased,it would just continue aletring the reaction until its used up.
The Manganese is not acting as a catalyst

Rahul sees a flock of birds. He watches as the flying birds land in neat little rows on several power lines. Which change of state does the motion of the birds most closely model? A) Melting B) Vaporization C) Deposition D) Sublimation

Answer : The correct answer is C.

Explanation :

Melting : It is a process in which a phase changes from solid state to liquid state. In this process the phase changes from more ordered place to less ordered place.

Vaporization : It is a process in which a phase changes from liquid state to vapor state. In this process the phase changes from more ordered place to less ordered place.

Sublimation : It is a process in which a phase changes from solid state to vapor state without passing through a liquid phase. In this process the phase changes from more ordered place to less ordered place.

Deposition : It is a process in which a phase changes from vapor state to solid state without passing through a liquid phase. In this process the phase changes from less ordered place to more ordered place.

As per the question, the motion of the birds changes from less ordered place to more ordered place. So, the motion of the birds most closely related to the Deposition.
