Quick look: In its modern sense, epigenetics is the term used to describe inheritance by mechanisms other than through the DNA sequence of genes. It can apply to characteristics passed from a cell to its daughter cells in cell division and to traits of a whole organism
When this happens, light changes speed and the light ray bends, either toward or away from what we call the normal line, an imaginary straight line that runs perpendicular to the surface of the object.
Even though the radishes watered with a 5.6 pH grew the best, they did not turn out to be the healthiest. The 7 pH radishes grew the most thick and sturdy. In conclusion, radishes watered with a low pH level do not grow to be tall and radishes watered with an exact acid level to neutral grow to be tall.
Answer:
0.767 g.
Explanation:
Molarity (M) is defined as the no. of moles of solute dissolved in a 1.0 L of the solution.
M = (no. of moles of K⁺)/(Volume of the solution (L).
<em>∵ no. of moles of K⁺ = (mass/molar mass) of K⁺.</em>
<em>∴ M = (mass/molar mass) of K⁺/(Volume of the solution (L).</em>
<em></em>
M = 0.0044 M.
Volume of the solution = 4459.0 mL = 4.459 L.
mass of K⁺ = ??? g.
molar mass of K⁺ = 39.01 g/mol.
∴ mass of K⁺ = (M)((molar mass of K⁺)(volume of the solution (L)) = (0.0044 M)(39.10 g/mol)(4.459 L) = 0.767 g.
