test tule 7) The steps of the scientific method, in the correct order, are A) design experiments, draw conclusions, collect data, interpret hypothesis B) find something interesting and make observations, formulate the data, interpret results, and draw conclusions. C) collect data, interpret results, test the hypothesis, conclusions D) collect data, interpret results, test the hypothesis, make observations E) none of the above. observations, ard results, make ations, formulate the hypothesis, design experiments, collec design experiments, make observations, and draw 8) What atom forms the backbone of almost all biological molecules? A) hydrogen B) nitrogern C) carbon D) sulfur E) phosphorus 9) Which one of the following biological polymers is mismatched with its monomer? A) DNA nucleotide B) enzyme amino acid C) chitin - monosaccharide D) protein - amino acid Dellulose-amino acid 10) Which of the following statements about the polymerization of macromolecules is EALSE? Often the energy needed for polymerization is supplied by ATP. B) The polymer chain usually has two different ends. Vater is added to join the monomers of the macromolecules A monomer is usually activated by the coupling of the monomer to a carrier. Macromolecules are synthesized by the stepwise addition of monomers. 11) An enzyme synthesized in the laboratory is found to have little activity when compared to the enzyme extracted from cell culture. Both enzymes were examined and have identical amino acid composition. Wh is the best explanation for the lack of activity of the synthesized enzyme? A) The van der Waals radius was altered during laboratory synthesis. e synthetic enzyme was not made of amino acids C) The ATP required for self-assembly was present in the cell extract but not in the laboratory synthesis. B) Denaturation of the synthesized enzyme was not complete. B) The synthesized enzyme was not folded correctly because chaperones, proteins that help other were not present. 12) lonic bonds are important in biological structures. Which of the following pairs of molecules would form ionic bond? A) two water molecules B)two amino acids with oppositely charged functional groups C) two different stereoisomers of the same sugar D) twofatty acids E) a water moleoule and a lipid
Explanation / Answer
Answer 7. B.
It is the correct order regarding an experiment.
First we find something interesting, then observation, then hypothesis, then design experiment, then data , then interpretation and then finally conclusion/result.
These are the basics of any scientific experiment.
Answer 8. Carbon= most fundamental in all biological molecules.
Answer 9. E. Cellulose is a polysaccharide.
