A Fume hood B Eyewash station C Emergency shower station

2

Diagram 2 shows a step in preparing onion cell slides. Why does the glass cover need to be placed at a 45° angle slowly?

A To prevent the onion epidermis from folding. B To prevent the formation of air bubbles under the glass slide cover. C To avoid drawing iodine drops so that they color the entire onion epidermis.

Diagram 4 shows the arrangement of the apparatus for an experiment studying the movement of matter through a Visking tube. After 5 minutes, it was found that the final level of the sucrose solution increased. What would be observed if the Visking tube was replaced with ice cream plastic?

A The level of sucrose solution does not change B The final level of the sucrose solution increases C The final level of the sucrose solution decreases D The final level of distilled water in the beaker decreases

6

A I and II B II and III C III and IV D I and IV

7

Diagram 6 shows a graph of energy change for a metabolic reaction with and without the presence of enzymes. A student found that product production increased rapidly when enzymes were added even though the experimental temperature was constant. What is the best explanation for this observation?

A Enzymes increase the kinetic energy of the substrate molecule B Enzymes increase the energy content of the product C Enzymes decrease the activation energy of the reaction D Enzymes provide heat energy to the product

8

Diagram 7 shows a phase in the mitosis process. What is the function of spindle fibers?

A Produce energy for cell division B Control the exchange of materials across the plasma membrane C Form the nuclear membrane during cell division D Pull chromosomes or chromatids to opposite poles of the cell

9
