Ques: Answer the following question given this paragraph: The acidity of a solution is typically assessed experimentally by measurement of its pH. The pOH of a solution is not usually measured, as it is easily calculated from an experimentally determined pH value. The pH of a solution can be directly measured using a pH meter (Figure 14.4). Q: The acidity of a solution is typically assessed experimentally by measurement of its what? Choices: - mass - density - color - ph A:
Ans: ph

Ques: Answer the following question given this paragraph: Cells in blood include red blood cells, white blood cells, and platelets. Q: Cells in blood include red blood cells, white blood cells, and what? Choices: - protons - droplets - plasmids - platelets A:
Ans: platelets

Ques: Answer the following question given this paragraph: All vertebrate organisms are in the phylum Chordata. Invertebrates, which make up about 95% (or more) of the animal kingdom, are divided into over 30 different phyla, some of which are listed below ( Table below ). Numerous invertebrate phyla have just a few species; some have only one described species, yet these are classified into separate phyla because of their unique characteristics. For example, sponges, with pores throughout their body, are from the phylum Porifera. Crabs and lobsters, with jointed appendages, are from the phylum Arthropoda. Q: Which phylum are all vertebrate organisms a member of? Choices: - pylum protozoa - phylum hominid - phylum arthropod - phylum chordata A:
Ans: phylum chordata

Ques: Answer the following question given this paragraph: Many simple sugars can combine by repeated condensation reactions until a very large molecule is formed. A polysaccharide is a complex carbohydrate polymer formed from the linkage of many monosaccharide monomers. One of the best known polysaccharides is starch, the main form of energy storage in plants. Starch is a staple in most human diets. Foods such as corn, potatoes, rice, and wheat have high starch contents. Starch is made of glucose monomers and occurs in both straight-chain and branched forms. Amylose is the straight-chain form and consists of hundreds of linked glucose molecules. The branched form of starch is called amylopectin. In the small intestine, starch is hydrolyzed to form glucose. The glucose can then be converted to biochemical energy or stored for later use. Q: What is the main form of energy storage in plants? Choices: - nitrogen - dioxide - liquid - starch A:
Ans:
starch
