During homeostasis, the action of effectors to amplify those changes that stimulate the effectors originally is known as negative feedback. (p. 7) |

| | A) | True |
| | B) | False |
|
|
16 | |

| | A) | True |
| | B) | False |
|
|
18 | |
Exocrine glands secrete chemicals through a duct that leads to the outside of a membrane and thus to the outside of a body surface. (p. 12) |
| | A) | True |
| | B) | False |
|
|
19 | |
The epidermis of the skin is keratinized, or cornified stratified squamous epithelium. (p. 12) |
| | A) | True |
| | B) | False |
|
|
20 | |
Epithelial membranes are attached to the underlying connective tissue by a layer of proteins and polysaccharides known as the basement membrane. (p. 12) |
| | A) | True |
| | B) | False |
|
|
21 | |
The eccrine (or merocrine) sweat glands, located in the axillae (underarms) and pubic region, secrete a protein-rich fluid. (p. 13) |
