The answer is D. A boy’s heart rate increases when running. Why? First of all homeostasis is all about balance in one’s body. So you can’t immediately cross out answer choices: a, b , and e. Those don’t talk about keeping balance within someone or an organisms body. And you can also immediately eliminate answer choice C because that answer choice is talking about inheritance which coincides with genetics. Lastly the heart rate increase to cool the boy’s body temperature. It’s trying to reach the equilibrium of the body temperature since it’s no longer at balance since he started running. That’s why he starts to sweat (I know that it doesn’t mention that but you should kind of get that since he’s running). Swear cools down your body.
Answer:
Brain, spinal cord, and nerves.
Explanation:
While they work together, each is an individual system.
Based on my observations, the earth rotates from west to east about the axis of rotation. The counter-clockwise rotation of the earth is as viewed from the North Pole star Polaris.
My observations supporting the counter-clockwise rotation of the earth are:
- The Sun rises in the east and sets in the west.
- All celestial objects including the stars and the moon rise in the east and set in the west.
The rotation is the result of the strong geomagnetic field of the earth. It is also responsible for the formation of day and night on the planet.

Speciation is one of the driving processes of evolution and results in the formation of new species.
<h3>What is evolution?</h3>
Evolution is the process by which new organisms are formed from existing organisms due to changes that result in increasing complexity of the organisms.
Speciation is the process by which new species are formed from existing species.
Therefore, it can be concluded that speciation is one of the driving processes of evolution.
