Answer:
I think it's D
Explanation:
Cause usually a scientist creates a hypothesis or theory so they can prove that it's true.
¯\_(ツ)_/¯
Part 1:
The carbon-monoxide, carbon-dioxide, and other harmful gasses are being released into the environment by the factory causing the air to be polluted.
Part 2:
The factory is putting in mechanical work, so the energy coming out is mechanical energy which is being transformed into chemical energy in the form of harmful gases.
Part 3:
This process is a recycling of carbon in the carbon cycle because along with adding carbon-dioxide to the air, it also provides photosynthetic autotrophs with carbon-dioxide which is required for photosynthesis. This will then be turned into oxygen which is used for cellular respiration in animals.
Answer:
decreases, has no effect on, increases
Explanation:
The kinetic energy of any object is dependent on two variables a) mass of the object and b) its velocity.
The mass of the object remains constant throughout the trajectory and only the velocity changes. As the object starts moving in upward direction gravity starts decreasing the velocity as it acts in opposite direction. As the object reaches the maximum height, gravity becomes ineffective as velocity has reduced to zero. As the object starts descending, velocity increases and hence the effect of gravity as the movement is towards the gravity.
The answer is E. Arctic temperatures are increasing; the arctic fox is hibernating for longer periods of time.
Since the temperatures are increasing, Winter becomes longer, giving organisms a longer time to hibernate. Hope I helped :)
