Answer: Humans and greater primates excrete water, broken down proteins and Urea. Many things cause unusual urine, Urea gives urine its yellow color a lack of urea can mean kidney failure. however it's hard to tell a lack of urea by just looking at urine as drinking excessive amounts of water turns the color clear and drinking caffeine turns the color reddish or brown so lab testing must be done
<span>B. cellular respiration takes place
The mitochondrion (plr. <em>mitochondria</em>) is a cell where the energy is synthesized and processes for many cellular processes. It is considered the power house of a cell. With this cell comes the cellular respiration process. </span>
Moles = Molarity * Volume
For HCl, Moles = 60 x 10^-3 * 1.2 x 10^-3 = 7.2 x 10^-5 moles
For NaOH Moles = 200 x 10^-3 * 5 x 10^-4 = 10 x 10^-5 moles
NaOh + HCl -> NaCl + H2O
7.2 x 10^-5 moles HCl reacts with 7.2 x 10^-5 moles NaOH to form
NaCl and H2O
After reaction, Moles of NaOH left = 10 x 10^-5 – 7.2 x 10 ^-5 =
2.8 x 10^-5 moles
Now volume = 260 mL = 200 + 60. So, [OH-] = 2.8 x 10^-5 / 260 x
10^-3 = 0.010769 x 10^-2 = 1.0769 x 10^-4
pOH = 3.679
