Question 13

Protists are organisms that are classified in their own kingdom. Protists are not plants or animals, yet some protists have characteristics similar to those of either plants or animals or both. A protist like the protozoan shown in the picture has similarities to both plants and animals. This protozoan is similar to animals because it has the ability to move from place to place while obtaining nutrients. This protozoan also shares a similarity with plants. Which feature labeled on the protozoan is associated with organisms in the plant kingdom but not in other kingdoms except protists?

Accepted Answer

Chloroplast

Answer

Mitochondrion

Answer

Flagellum

Answer

Question 14

A student investigates the process of passive transport by the cell membrane by creating a model. The student puts a starch solution in a dialysis tubing bag. The bag is then placed in a beaker that contains an iodine solution. The dialysis tubing bag is semipermeable. The student's observations are in the table. The student concludes that the iodine passes through the dialysis tubing material but the starch molecules cannot. Which two statements provide evidence to support the student's conclusion?

Accepted Answer

The starch solution turned blue-black after the bag was placed in the beaker.

Accepted Answer

The iodine solution did not change color after the bag was placed in the beaker.

Answer

The iodine molecules passed through the bag because they are not the same size as the starch molecules.

Answer

The starch solution did not react with the iodine solution after the bag was placed in the beaker.

Answer

The change in color of the iodine solution was due to a student error in procedure.

Question 17

The photograph shows a two-toed sloth. These slow-moving organisms cannot outrun or outclimb predators, so they spend most of their time hanging from branches in trees.
