Anna [14]4 years ago
8 0

<u>Answer:</u>

<em>Solution of pH 7 contains thousand times more hydrogen than the solution of pH 10. </em>

<u>Explanation:</u>

<em>pH of A substance is given by the negative of the logarithm of concentration of hydrogen ions.</em> It is given by the equation

pH=-log \ [H^+ ]

<em>Here the initial pH is given as 7. We have to calculate the concentration of H^+ ions. </em>

7=- log[H^+ ]  [H^+ ]=10^-^7

<em>The final solution has a pH 10. We have to calculate the concentration of H^+  in this case </em>

pH=-log[H^+ ] 10=-log [H^+ ][H^+ ]=10^-^1^0

Next we have to calculate how many times more is the H^+ ion concentration in the solution of pH 7 when compared to the solution with pH 10.

\frac {10^-^7}{10^-^1^0} =10^3=1000

<em>Thus the concentration of H^+ ion in the solution of pH 7 is 1000 times more than the solution of pH 10. </em>

The food we consume is then processed and essentially extirpated into two forms, waste and nutrients. The nutrient rich category is used, or stored for when needed. Similarly, sugar is either used for energy once consumed, or stored in fat cells for when needed.

vivado [14]
I would say that Melissa has made the mistake of using the same uncleaned cutting board first for cutting up chicken which is notorious for forming bacteria quickly when out of the fridge and then chopping vegetables on it thus running the possibility of contaminating the vegetables with chicken bacteria. She should ensure she washes the cutting board carefully with soap and water to avoid contamination of the vegetables.

Why do we compare the dermal tissue of plants to human skin? Explain your answer.
Over [174]

Answer:

They are like each other

Explanation:

Your skin covers your body, protecting it from abrasion, water loss, and infection and secreting conditioning substances. The epidermis of a plant serves similar functions. Usually a single layer of closely-packed cells, epidermal tissue covers leaves and young stems and roots of vascular plants. Most epidermal cells secrete waxy substances which form a cuticle, or waterproof covering, over the aerial surfaces of the plant, such as the stems and leaves. The cuticle also resists viral, bacterial, and fungal invasion.
