Answer: A chemical reaction is the change of a substance into a new one that has a different chemical identity. In summary, a chemical reaction is a process that converts one or more substances to another substance. Chemical reactions start with reactants and convert them into products. Most chemical reactions inside living things are regulated by enzymes, which speed up chemical reactions.A chemical reaction is a process that changes or transforms one type of chemical into another. ... Life is the result of countless reactions happening all at the same time, most often between carbon, hydrogen, nitrogen, and oxygen atoms. Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. ... A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

Answer:
The involvement of more than two genes.
Explanation:
The polygenic characteristics have many phenotypes because more than two genes governs the phenotype of individual organism. The single gene contains a pair of alleles that codes for two phenotype and two genes will code for 4 phenotype. Thus, more than two genes for example, three genes will have six phenotypes.
The skin color and height are polygenic characterstics in humans.
Answer:
all of the above
Explanation:
Water biomes describe all the living things living in an area of water such as a lake or ocean. The surrounding environment plays a huge part in what organisms able to live there.
For example, green plants and algae require sufficient sunlight and oxygen to perform photosynthesis. Green plants and algae are an important food source for many other organisms. The amount of salt is important for various fish, as they will be unable to survive in very high salt concentrations. Therefore, all of the above are limiting factors.
The correct answer is glycolysis.
Glycolysis is an anaerobic process of splitting a molecule of glucose (6 carbons) to 2 molecules of pyruvate (3 carbons each). Glycolysis does not require the presence of oxygen and will still produce energy, albeit lower than aerobic metabolism. In the absence of oxygen, fermentation can occur wherein pyruvate is further converted into lactate.
