Answer:
The overall cell potential can be calculated by using the equation E0cell=E0red−E0oxid. Step 2: Solve. Before adding the two reactions together, the number of electrons lost in the oxidation must equal the number of electrons gained in the reduction. The silver half-cell reaction must be multiplied by two.
Explanation:
The correct answer is active hyperemia.
Active hyperemia represents the increase in organ blood flow (hyperemia) that is associated with the increased metabolic activity of that organ. In this case, the increase in blood flow accompanies muscle contraction during the exercise. Muscle contraction stimulates the production of vasoactive (vasodilative) substances that dilate the vessels and thus, bring more oxygen to the muscles.
The question is incomplete. The rest of the question is :
From these experiments, Mendel developed four hypotheses. They include all but ___________. A. One heritable factor may be dominant and mask the other factor. B. Any organism that "shows" a heritable factor must be homozygous. Eliminate C. An organism has two "heritable factors", now called genes, one from each parent. D. sperm or egg carries only one heritable factor for each trait in the offspring.
Answer:
<em>The hypothesis which is excluded is B 'Any organism that "shows" a heritable factor must be homozygous.'</em>
Explanation:
The hypothesis is wrong because even heterozygous traits are heritable.
The hypothesis mentioned in option B cannot be considered correct because Mendel's studies showed that all traits can be inherited from the parents. All factors whether dominant or recessive, homozygous or heterozygous are heritable characteristics. Mendel's study also confirmed that genes might carry homozygous or heterozygous alleles and these alleles independently assort into gametes and are heritable.
All other hypotheses are correct and their authenticity was validated after Mendel performed his experiments.
