Answer:
It is because of Various things that we do, If we did not exist, several animals that went extinct because of us, would have thrived, If it wasn't for us filling the sky with so much CO2's, we wouldn't have the Earth heating up even more. Also, other things that we do such as Urbanization, Desertification, and Deforestation. All of these words will be defined under this text.
Explanation:
Deforestation: When humans cut down too many trees can result in habitat loss/ more CO2's
Desertification: When land used to be a grassland but humans used too much of a resource and turned it into a hot, sandy wasteland.
Urbanization: When you take land and fill it with tons of buildings, homes, and businesses. This can result in over-crowding, and spreading of diseases.
Answer:
They are directly proportional
Explanation:
when the kelvin temperature increases, the average kinetic energy of particles increases and they move faster and vice versa.

Answer: Reflectors use a mirror to collect the light, whilst refractors use a lens while, Refractor telescopes require a large lens at the front to direct the incoming light to the lens.

Answer:</h3>
The concentration of the diluted salt solution decreased
<h3>
Explanation:</h3>
When a solution is diluted the concentration of then solution decreases and the volume of the solvent increases.
In this case;
The initial concentration is 0.50 M
The initial volume is 10.0 mL
The volume after dilution is 100 mL
We are required to determine the change in the final concentration;
According to the dilution equation;
M1V1 = M2V2
M2 = M1V1 ÷ V2
Therefore;
M2 = (0.5 M × 10.0 mL) ÷ 100mL
= 0.05 M
Therefore, the concentration of the solution decreased after dilution.
