This is associative learning.
The reactions of George and Ken are based on when they are startled. George will learn to associate his sister's crying with him being startled because it happens every time his sister cries.
Whereas Ken will not know when his sister will cry or when he will be startled by the crying so this has no affect on Ken.
Hence, crying will affect George but not Ken.
Since, the options are not given the question is incomplete. The complete question is as follows:
Presentation of a rewarding stimulus serves as ______, while removal of an aversive stimulus serves as ______.
a. negative punishment; positive punishment
b. reinforcement; punishment
c. positive reinforcement; negative reinforcement
d. negative reinforcement; positive reinforcement
e. positive punishment; negative punishment
Answer: c. positive reinforcement; negative reinforcement
Explanation:
Both positive and negative reinforcement are the parts of conditioning. In positive reinforcement the subject is awarded for the particular sets of desired behavior but it is opposite for the negative reinforcement the subject is punished for undesired behavior.
In positive reinforcement favorable stimulus is chosen by the subject which made the subject to avail the reward whereas in the negative reinforcement , the aversive stimulus is intended to reduce the undesired behavior by punishment.
Answer:
48 amino acids
Explanation:
The wild type gene codes for a protein with 100 amino acids. One amino acid is encoded by one triplet code of the gene. This means that the wild type gene has a total 100 triplets or 300 nucleotides to code for a protein of 100 amino acid. Mutation in this protein has introduced the code "UAA" at the 49th codon. The code "UAA" is a stop codon. Therefore, the mRNA transcribed from the mutant allele would code for a protein having 48 amino acids as the protein synthesis will be stopped once the stop codon at the 49th position is read.
These dark areas are called maria. They are thought to be formed by volcanic eruptions in the moon's history.hope this helped:)
