Answer:

The answer is mitotic nondisjunction of X Chromosomes.

Explanation:

Nondisjunction is a type of error that occurs resulting in daughter cells with chromosome numbers that are abnormal (aneuploidy). Due to the error in chromosome numbers, it gives rise to conditions such as Down Syndrome (Trisomy 21) and Turner Syndrome (Monosomy X). Nondisjunction can be caused by;

1. Failure of separation to occur in a pair of homologous chromosome during meiosis I.

2. Failure of separation between sister chromatids in Meiosis II.

3. Failure of separation between sisters chromatids in mitosis.

This gives the 45,X in Turner syndrome. The other X chromosome is partly or completely missing. Hence, the female is born with only one X chromosome.

Which measure of memory retention is the most useful for assessing the strength of an implicit memory?
erica [24]

Answer:

Implicit memory is occasionally called unconscious storage or automatic stored. Implicit memory uses past experiences without thinking about things. Previous experiments, no matter how long such experiences have taken place, enable implicit memory performance.

Explanation:

Implicit memory, procedural memory, allows us to do many physical daily activities, like walking and cycling, without thinking. Much of the implied memory is procedural in nature.

Procedural memory involves mainly new motor skills and is dependent on the brain and baseline ganglia.

When someone sings the first few words, remember the words to the song.

<u>Answer: </u>

'An air puff in the eye elicits an eye blink' is the statement that illustrates a US-UR pair.

Option: (B)

<u>Explanation: </u>

  • When an event generates an unconditioned stimulus, it is often followed by an unconditioned response spontaneously.
  • This kind of stimulus is usually unavoidable and makes the subject vulnerable to respond in a specific manner that is expected for the type of stimulus received.
  • The correlation between US and UR is characterized by the input-output link that is apparent in any given event.
