Oligarchy comes from the greek word "oligos" which means " a few" and the word "archos" which means "to Govern", so it is a government system where all the power is gathered by a small group of people, usually richest families in the city or country, it isn´t seen as an open democracy because not only they run the destinities of the country but also develop and create the rules, the law, and manage all the system. Back then we also could find that power in the hands of the oldest men in the country who controlled everything and had a lot of economic power.
The correct answer is <span>conditioned stimulus.
The most famous explanation of a conditioned stimulus is from Ivan Pavlov's classical conditioning study. In his study a bell was repeatedly rang (neutral stimulus) before dogs were presented with food (unconditioned stimulus) that made them salivate in response (unconditional response). After repeated pairing of the neutral stimulus with the </span>unconditioned stimulus, the sound of the bell alone elicited a response of salivation in dogs. In this this instance, the conditioned stimulus is the sound of the bell.
Allele frequency is used to display the genetic diversity of a species population .
Explanation:
To calculate the frequency of the recessive allele we use the
THardy-Weinberg equation
p² + 2pq + q²
p+q=1
p is the frequency of the homozygous dominant genotype
q is the frequency of the homozygous recessive genotype
2pq is the frequency of the heterozygous genotype.
Total number of individuals = 45 + 30+ 25 = 100
So, the frequency of recessive trait = 25/100 =0.25.
Thus, the value of q² = 0.25
So, q would be equal to square root of 0.25 which comes out to be 0.5
