The correct answer is option B and C, that is, they do not share similar stimulus characteristics and include a restricted number of stimuli.
An arbitrary stimulus class refers to predecessor stimuli, which induce the similar reaction, however, they do not share relational feature and do not resemble each other in physical form. For example, cheese, peanuts, chicken breasts, and coconut milk are the members of an arbitrary stimulus class if they induce the response, that is, sources of protein.
Answer:
Theories and laws
Explanation:
A scientific theory is important because it is an explanation of an aspect of the natural world that can be repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results. Theories can be proven or rejected, just like hypotheses. Theories can be improved or modified as more information is gathered so that the accuracy of the prediction becomes greater over time.
A scientific law is important because it is a description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of a phenomenon is a scientific theory.
Scientific laws do not have absolute certainty (as theorems do), and it is always possible for a law to be contradicted, restricted, or extended by future observations.
Answer:
forward; reverse
Explanation:
Chemical equilibrium is a state where there is no tendency to change; the situation is stable.
This occurs when the reaction rate of the forward reaction is equal to the reaction rate of the reverse reaction. This is because when no rate is greater than another, the situation will remain the same.

Answer:
1. Cytogenetic mapping.
2. Linkage mapping.
3. Physical mapping.
Explanation:
1.<u> Cytogenetic mapping - Gene localization using microscope.</u>
A cytogenetic mapping is defined as the visual appearance of genes when seen by using microscope. The genes are stained and seeing under microscope that shows visually distinct regions, called dark and light bands and provide unique appearance to the genes.
2. <u>Linkage mapping - recombination distance s measured using genetic crosses.
</u>
Linkage mapping is done using linkage analysis by observing the genes linked to the offspring. It do not show physical distances but only shows genetic distances and how the two genes inherited together.
3. <u>Physical mapping - Determine nucleotide sequence distance using DNA cloning.</u>
Physical mapping is a technique by which physical distance between DNA base pairs can be evaluated with the help of DNA makers and also determine DNA base pairs sequences with high accuracy.
