Individual with genotype AaBBCC has the dark skin colour.
Explanation:
The skin colour is a polygenetic trait i.e two or more genes control the particular characteristic in an individual.
The amount of gene in the individual in such cases would determine the skin tone.
It is given that dominant alleles are responsible for darkest colour of the skin in the example. We could see that the genotype AaBBCC has maximum dominant alleles which makes us to deduce that individual with this genotype will have dark skin phenotype.
This quantitative occurrence of alleles in the individual decides its skin colour and variations in it.
The genes are independent of each other but have an additive effect on the phenotype like skin colour.
Answer:
Placebo effect
Explanation:
People tend to think they've been cured by something even if the something isn't effective, and they might even experience minor symptoms of having been effectively treated. If people know that the drug they're being given is the one being tested, they'll be more likely to experience this effect because it's the drug that the researchers think is going to work. Researchers conduct double-blind studies to prevent bias in the researchers and to prevent the placebo effect from interfering with the results from the test subjects.

B
Explanation:
Hes the inventor of the punnet square. Sorry not enough info but that is your answer.
When the body becomes dehydrated, a chemical signal is sent that causes nephrons in the kidneys to absorb more water and excrete more salts. This is an example of a <em>D Feedback loop</em>.
The correct answer is D. The flavor of carrots grown under different conditions is compared.
Qualitative observation is the observation which deals with describing the quality of a thing by observing its properties with our senses, without discussing the numerical values. Examples of qualitative observations are observing colors, texture, and shape, size flavor of a thing. Therefore, the comparison of flavor of carrots grown under different conditions is a qualitative observation.
