What would your hypothesis be if you found a cluster of fuzzy black growth in an empty plastic container in your cabinet? 1. The container gave rise to this growth. 2. There were microscopic portions of this growth that gave rise to this larger colony. 3. The fuzzy growth is not a growth, but part of the container. 4. The fuzzy growth generated spontaneously in the container after you put it in the cabinet. Biology: Life on Earth, 9e Copyright © 2011 Pearson Education Inc.

A cell’s membrane is not formed properly—it is not able to act as a barrier to its environment. What may cause this problem? 1. The ER is malfunctioning and cannot produce the proteins for the membrane. 2. The ER is malfunctioning and cannot produce the phospholipids and cholesterol for the membrane. 3. The mitochondria are malfunctioning and cannot produce the phospholipids and cholesterol for the membrane. 4. The chloroplasts are malfunctioning and cannot produce the energy needed to move molecules across the membrane. Biology: Life on Earth, 9e Copyright © 2011 Pearson Education Inc.
