Answer:
See the answer below
Explanation:
<em>Recall that the law of dilution states that the number of moles before dilution must be equal to the number of moles after dilution.</em>
Mathematically,
molarity x number of moles before dilution = molarity x number of moles after dilution.
For solution A: final molarity = 3 mM, final volume = 2mL, initial molarity of KMnO4 = 10 mM
Applying the equation:
10 x initial volume = 3 x 2
initial volume = 6/10 = 0.6
<u>Hence, Tube A should be made with 0.6 mL of 10 mM KMnO4 stock and 1.4 mL of distilled water to give a solution of 2 mL 3 mM KMnO4.</u>
For solution B:final molarity = 8 mM, final volume = 2 mL, initial molarity = 10 mM
10 x initial volume = 8 x 2
initial volume = 16/10 = 1.6
<u>Hence, Tube B should be made with 1.6 mL of 10 mM KMnO4 stock and 0.4 mL of distilled water to give a solution of 2 mL 8mM KMnO4. </u>
Answer: Evolution
Explanation:
Evolution can be defined as the change in the characteristics of the species over a period of time which basically relies on the process of the natural selection.
The characters that allows the survival of the organism is favored and is known as the survival of fittest which is a natural selection.
This is known as evolution in which the herbicide resistant plant is favored more and has developed over a period of time.
<span>The yeast will produce the most cellular respiration at an optimum temperature. This temperature will be at a normal room temperature. If the temperature of the environment surrounding the yeast is too low, the rate will decrease, because the molecules involved in the process of cellular respiration will slow down resulting in lesser rate. In addition, if the temperature of the environment surrounding the yeast is too great, the rate will also decrease, because the enzymes involved in cellular respiration will denature causing the rate to decrease. Therefore, the yeast will have the greatest rate of cellular respiration at room temperature. </span>
The two fundamental principles used in building cladograms are principles of parsimony and robusticity.
The principle of parismony states that the simplest of competing explanations is the one most likely to be correct.
The principle of rubusticity states that trees that maintains their basic forms even when different options are applied to the sequence of changes in one or more of their branches are preferable.<span />
