Beth and joe meet in bio 1a lab at u.c.s.b. they begin to study together and ultimately decide to marry after graduation. upon m
eeting each other's family the night before the wedding ceremony, they discover that beth's sister has the same rare recessive disorder as joe's brother. when beth realizes this, she begins to have doubts about marrying joe. the family pedigrees are shown below:
1 answer:
Answer:
The chances of Beth's and Joe's Child having a child with the recessive trait is 0%----25%
Explanation:
(PICTURE OF THE FULL QUESTION IS ATTACHED BELOW)
Since both Beth and Joe have siblings expressing the recessive trait, this means that their parents are both carriers. This means that Beth and Joe are either both carriers, both normal, or one normal and one carrier. When crossed this would bring the possible outcome of a recessive phenotype between 0%-25%

Question:
<em>The diagram shows the potential energy changes for a reaction pathway.</em>
Part 1: Does the diagram illustrate an endothermic or an exothermic reaction? Give reasons in support of your answer.
Part 2: Describe how you can determine the total change in enthalpy and activation energy from the diagram and if each is positive or negative.
Answer:
Part 1: The diagram illustrates an endothermic reaction as the products has a higher potential energy than the reactants do. There is a positive slope of the diagram and there is enough energy to meet the activation energy requirement.
Part 2: You can determine the total change in enthalpy and activation energy from the diagram by the potential energy of the reactants. If the reactants have a high potential energy, then the enthalpy is also high, and if the reactants have a low potential energy, then the enthalpy is low. You can determine if the diagram is positive or negative by knowing if its an endothermic or exothermic reaction. An endothermic reaction is positive because the products are higher than the reactants and a exothermic reaction is negative because the reactants are higher than the products.
