|
|
|
| 17 | |
In the nervous system, neurons are specialized to conduct electrical information and continue to divide during the life of the individual. |
| | 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. |

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

|
| 21 | |
The eccrine (or merocrine) sweat glands, located in the axillae (underarms) and pubic region, secrete a protein-rich fluid. |
