Apologia Advanced Biology Module 2

The secretions of an exocrine gland are examined, and it is determined that there is cytoplasm in the secretions. This narrows the type down to two. Then it is found that there is DNA in the secretions. Which type is it?

• apocrine

• holocrine

An exocrine gland secretes a substance that is rich in cytoplasm and phospholipids but no other cellular material. What kind of exocrine gland is it?

• apocrine glands

• holocrine glands

Looking at some tissue under a microscope, you notice that the cells are in little pockets. Is this connective tissue proper or cartilage?

• proper

• cartilage

An organ’s parenchymal cells are stable. If the organ gets damaged, can it be repaired to 100% working order again? Is the healing process slow or relatively quick?

• Not 100% but with a quick healing process

• 100% healing with quick healing response

• 100% healing but with slow healing process

• Not 100% healing and slow healing process

How do epithelial cells get oxygen and nutrients?

• diffusion

• osmosis

Order the three simple epithelial tissue types in terms of increasing distance between the free surface and the basal surface.
