Answer:
Acid pH is <u>1</u> to <u>6</u>, base pH is <u>8</u> to <u>14</u>.
Explanation:
The pH scale ranges from 1 to 14 with 7 being neutral, 1 being the most acidic and 14 being the most alkaline. As you progress further to the left of the scale, substances get more acidic while moving to the right gives you substances that are more alkaline.
Hope this helps :)
The answer is C. Sugar, because cells use sugar as energy to function
A Community or an ecosystem if you include the habitat the animals are living in
Answer:
D
Explanation:
Let's assume there's two cuboidal cells, cell A and B
Cell A has a side of x
Let's find the surface area of cell A
SA = 6(L²)
SA = 6(x²)
SA = 6x²
Let's find the volume of cell A
V = L³
V = (x)³
V = x³
Cell B has a side of 2x
Now let's find the surface area of cell B
SA = 6(L²)
SA = 6(2x)²
SA = 24x²
Let's find the volume of cell B
V = (L)³
V = (2x)³
V = 8x³
As you can see, just by doubling the side length, the ratio between Surface Area and Volume went from 6/x to 3/x (the x² in the numerator and the x³ in the denominator cancel out forming 1/x)
The ratio decreased, therefore, D is the statement that makes sense
