Answer:
Your answer is probably A). If you find a fossil of an armored fish in layer A, and you find a fossil of a trilobite in layer B (five layers deeper), then you can safely assume that the trilobite is older than the armored fish.
The answer is oropharynx.
The reason for this type of epithelium in this region of the respiratory tract is due to
its proximity to the esophagus. This
means that this region of the respiratory
tract is subject to abrasion by food
passing down the esophagus. This
epithelium is continuous with that of the esophagus.
Answer:
Bile is a fluid that is made and released by the liver and stored in the gallbladder. Bile helps with digestion. It breaks down fats into fatty acids, which can be taken into the body by the digestive tract.
Explanation:
When digesting fats, bile acts as an emulsifier to break the large fat globules into smaller emulsion droplets. Emulsified fats provide a larger area for the fat-digesting enzymes (lipase) to act, making the process quicker. Bile acts as a good solvent.
