Answer:
B. Set 2
Explanation:
Carbohydrate is one of the four biological molecules in living systems (others are proteins, lipids and nucleic acid). The carbohydrate molecule consists of a long chain of carbon, hydrogen and oxygen elements in a ratio 1:2:1. Hence, the simplest unit of a carbohydrate has an empirical formula of (CH2O)n where n is the number of chains.
According to the question, a store sells a variety of sets for building molecular models and Kendra wishes to build a model of a carbohydrate molecule. Since carbohydrate monomers have a CH2O formula, Kendra needs a set in which the ratio of carbon: hydrogen: oxygen is 1:2:1. SET 2 fits this description by containing 12 carbon, 12 oxygen, and 24 hydrogen atoms
That is, carbon (12/12) : hydrogen (24/12) : oxygen (12/12), which is 1:2:1. Therefore, SET 2 is the best choice for Kendra in order to build her model of carbohydrate molecule containing as many monomers as possible.
Background research to note if your unsure what some terms mean/are:
- Hormones and Enzymes play a vital role in our body by controlling and regulating many functions.
- Hormones are known as chemical messengers as they trigger many functions
- Enzymes are catalysts as they affect the rate of a reaction
- A Pathogen is a bacterium, virus, or other microorganism that can cause disease.
Answer:
Although something that is similar with all is all can trigger, control, and affect the body in some way.
