Answer:
Option D
Explanation:
Options for the question
A) The Y chromosome is slower to mature than the X chromosome.
B) Replication of the X chromosome occurs more often in males.
C) Male hormones cause the expression of X-linked traits.
D) Males only have one copy of the X chromosome
Given-
Duchenne muscular dystrophy (DMD) is an X-linked recessive condition which means it will occur in male even if they have one diseased X gene. While females will have this disease only when they have two diseased X gene
Hence, in most of the cases women with only one diseased X chromosome act as carrier and show normal traits.
Let us assume X is normal gene and X' is the diseased gene then
Genotype of normal father will be - XY
Genotype of carrier mother will be - XX'
Now if these two mates, following offspring will be produced
XY * XX'
XX, XX', XY, X'Y
So the male with X'Y will have DMD
Hence, option D is correct
Answer:
Part A:
<u>Encoding failure</u>: This applies to the the AP exam because if the terms are not consciously read and studied, it won’t be encoded, and it won’t be remembered. This influences failure on the exam, rather than success.
<u>Predictive validity</u>: Regarding the AP exam, the test is made to predict the future behaviour of the student within the course. Therefore, if the test score is high, the retention of content in the future should be higher than that of a person with a lower test score. The same can be said for the AP course or the AP practice tests. These resources are made to predict what the test score is most likely to be, if the test has predictive validity.
<u>Distributed practice</u>: This will influence success on the AP exam because it allows for better recall rather than recognition, so writing the portion will be more successful.
<u>Proactive interference</u>: This could influence failure on the AP exam because previously learned information such as learnings from biology class or chemistry class can interfere with the newly learned information from psychology, especially since these subjects can cross content.
Part B:
<u>Procedural memory</u>: In a performance task, procedural memory comes in handy because writing letters or typing is easy without thinking about it.
<u>Acetylcholine</u>: This can lead to failure on the performance task because procedural memory might be impaired or recognition of everyday material might exacerbate the difficulty of the already challenging task.
<u>Emotional intelligence</u>: Having high emotional intelligence would influence success in the performance task because it allows for greater creativity when thinking of issues about others and when solving issues.
