Natural selection occurs to give help the best survival chance to the organisms.
A food is something that provides nutrients. Nutrients are substances that provide: energy for activity, growth, and all functions of the body such as breathing, digesting food, and keeping warm; materials for the growth and repair of the body, and for keeping the immune system healthy. (So we don’t die:))
Explanation:
Option 1.
4y=12
Dividing 4 both sides
y=3
Division property should be used.
Option 2.
![\dfrac{y}{4}=12](https://tex.z-dn.net/?f=%5Cdfrac%7By%7D%7B4%7D%3D12)
Cross multiplying each other,
y=12(4)
y=48
Option 3.
2(4y)=12
Opening bracktet in LHS
8y=12
Dividing both sides by 8 i.e.
![y=\dfrac{12}{8}\\\\y=\dfrac{3}{2}](https://tex.z-dn.net/?f=y%3D%5Cdfrac%7B12%7D%7B8%7D%5C%5C%5C%5Cy%3D%5Cdfrac%7B3%7D%7B2%7D)
Division property is used.
Option 4.
y+4=12
Subtracting both sides by 4 i.e.
Y+4-4=12-4
y=8
Subtraction property is used.
<em><u>It means that in option (4) Soo-Jung used the subtraction property of equality to solve an equation for y.</u></em>
Space is filled with nothing.
Space is the absence of matter.
Hope this helped
