When did you notice a greater elevation of blood pressure and pulse?

Physics
1 answer:
ch4aika [34]2 years ago
6 0
You would notice a greater elevation of blood pressure and pulse when an individual experiences hypertension. It is also known as high blood pressure. When blood vessels are blocked or are constricted due to several reasons, the pressure of the blood would be increased since there would be smaller area for the blood to flow. Consequently, the pulse or the heart rate would increase as well due to the increase in pressure. Factors that can cause hypertension would be lack of exercise, stress, when hormones are not regulated. It can also be caused by another illness like diabetes, kidney disorder,  obesity and many other.

Which of the following describe advantages of using radio waves over other electromagnetic waves to transmit information to Eart
Whitepunk [10]

The correct options are:

D

"Radio waves have a lower frequency, which makes them safer for humans."

B

"Radio waves take less energy to produce."

<h3>Why do we radio waves over other electromagnetic waves to transmit information to Earth? </h3>

Radio waves are electromagnetic waves with frequencies on the range from 10 KHz to 10 THz.

Now, remember that all electromagnetic waves have the same speed, which is the speed of light, and the energy of a wave is proportional to its frequency.

Particularly, we can see that radio waves have small frequencies (smaller than infrared light) so these waves carry very little energy.

With that in mind, the correct options are.

D

"Radio waves have a lower frequency, which makes them safer for humans."

B

"Radio waves take less energy to produce."

These are the two main reasons of why we use radio waves.

How does an environmental change (ex. hurricane, drought, etc.) affect the organisms that are adapted to the environment before
rjkz [21]
The environmental changes can will negatively affect different organisms differently, for example some organisms might die due to failure of the organisms to adapt to the new changes. Some organisms will be forced to migrate in order to counter these changes, this may lead to this organisms leaving their old living routine and adapt to the new methods of living, this may lead to evolution caused by new environment.
