- Q9
A student conducts an experiment to determine the effect of pH on the enzyme amylase, which converts starches into sugars. For the experiment, the student fills 14 test tubes with a starch solution each at a different pH, then adds 1 mL of amylase to each test tube. One at a time, the student adds three drops of iodine solution to each test tube. Iodine turns bluish-black in the presence of starch. The student records the time taken for a color change to occur in each test tube.
Which question can be answered by this experiment?
What pH in the body is ideal for the enzyme amylase to be the most active?
How many seconds does 1 mL of the enzyme amylase require to break down 1 g of a basic starch solution?
Which part of starch is broken down first by the enzyme amylase in an acidic solution?
Which type of sugar is formed by the breakdown of starch by the enzyme amylase?
30s - Q10What is the primary function of restriction enzymes in biotechnology?To synthesize proteinsTo replicate RNATo amplify DNATo cut DNA at specific sequences30s

- Q12What is gene therapy primarily used for?To enhance physical appearanceTo treat genetic disordersTo improve athletic performanceTo create new species30s
- Q13Which of the following best describes cloning in biotechnology?Altering genes to enhance traitsCombining DNA from different speciesCreating a genetically identical copy of an organismRandomly breeding plants for new characteristics30s
- Q14
Huntington’s disease is a rare neurological disorder characterized by the progressive breakdown of the nerve cells in the brain. Once a nerve cell forms, it does not undergo mitosis. Huntington's disease is slow to develop, with the first signs of the disease beginning to appear in people between 30 and 50 years old. The disease is completely dominant and is passed down through families as a dominant gene on chromosome 4. A pedigree shows the transfer of genes in a family that has a known history of Huntington’s disease. Some family members have been tested, and others have not received testing for the disease. Which addition to the model in Figure 1 will show how cell differentiation is involved in the formation of the nerve cells?
Show how the stem cells remove parts of their genetic material.
Show how the stem cells activate specific genes within their DNA.
Show how the stem cells collect cellular parts from old nerve cells.
Show how the stem cells transfer energy between other cells.
30s - Q15
Organism 1 inherits a mutation from its parents. Organism 2 is exposed to a substance in its environment that causes a mutation. Which of these best describes how the mutations are different?
The mutation in Organism 1 first appeared in a gamete.
The mutation in Organism 2 began as a partial deletion of a chromosome.
The mutation in Organism 1 is limited to a single organ.
The mutation in Organism 2 contains a gene substitution.
