Epithelial tissue is polar.
-
True
-
False
Correct Answer
A. TrueExplanation
Epithelial tissue is polar because it has distinct apical and basal surfaces. The apical surface is exposed to the external environment or a body cavity, while the basal surface is attached to a basement membrane. This polarity allows epithelial tissue to perform functions such as absorption, secretion, and protection effectively. The apical surface may have specialized structures like microvilli or cilia, while the basal surface is responsible for anchoring the tissue to the underlying connective tissue.Rate this question:

What is the term for the movement of food through the digestive system?
-
Peristalsis
-
Eustacian
-
Olfaction
Correct Answer
A. PeristalsisExplanation
Peristalsis is the correct answer because it refers to the rhythmic contractions of the muscles in the digestive system that propel food forward through the digestive tract. These wave-like movements help to push food and liquids from the esophagus into the stomach, and then through the intestines for digestion and absorption of nutrients. Eustacian and olfaction are not related to the movement of food through the digestive system.Rate this question:
