Answer:
C. Quantitative characters are due to polygenic inheritance, the additive effects of two or more genes on a single phenotypic character.
Explanation:
Mendel studied the discrete traits that were present in observable contrasting phenotypes. Tall or dwarf stem, purple or white flowers, round or wrinkled pods are some of the examples of discrete traits. Each of these traits is mostly regulated by two alleles of a gene.
On the other hand, a polygenic trait is the one that is regulated by more than one gene. Quantitative traits are polygenic traits. The alleles of all the genes that regulate a quantitative trait have an additive effect on the phenotype. For example, human skin color is a quantitative trait and shows continuous variation. There is a range of human skin color regulated by the sum total of effects of all the alleles of the regulatory genes present in an individual.
An individual with "aabbcc" genotype would have very light skin color while an individual with "AABBCC" genotype would have a very dark skin color. The skin color of the intermediate genotype would be in between these two extreme phenotypes.
Answer:
Increases many different skills such as your observance, your ability to ask questions, your ability to conduct different types of experiments.
Explanation:
The scientific method is a way of answering questions using science. The steps of this method usually ask you to formulate a hypothesis and then check your hypothesis by conducting experiments. Conducting those experiments and being very observant gives you the information you need to recheck your hypothesis to see if it's correct, therefore answering your question.

Measure the amount of energy in the phytoplankton and the amount of light entering the aquarium. Then measure the amount of energy in the phytoplankton after exposure to the light and determine the difference.
Explanation:
Phytoplanktons like most of the plants use chlorophyll, sunlight and carbon di-oxide for photosynthesis but it depends on other organisms to consume extra energy as they are unable to gain enough energy from their consumption of light. This differs among the different species of planktons.
It can be observed in an aquarium that a phytoplankton is gaining less energy than the energy they have absorbed by the light and this can be done by measuring the energy before and after the photosynthesis.
The liver stores glucose as glycogen and converts excess glucose to glucagon.
