Due to their function, nerve fibers which carry afferent impulses are known as afferent nerves or sensory nerves, and those nerve fibers which carry efferent impulses are known as efferent nerves or motor nerves.
Answer:
Older fossils are found in deeper layers of sedimentary rock.
Explanation:
The relationship between undisturbed sedimentary rock layers and fossils is that older fossils are found in deeper layers of sedimentary rocks.
This is one of the premise of the law of superposition and principle of fossil and fauna succession.
- An undisturbed sequence is one in which the sedimentary layers have been arranged sequentially.
- The oldest is at the bottom and the youngest on top.
- Also, fossils grade in this manner too.
- The oldest fossils will be in the oldest bed which is the deepest layer.
- The youngest bed will contain the youngest fossils in like manner too.
Answer:
B) fats
Explanation:
Common hepatic duct is s the part of the biliary tract which means that is involved in the secretion of bile.
Bile salts secreted from the bill have an important role in emulsification of lipids (fats). They have the ability to aggregate around lipids thanks to their amphipatic nature. Amphipatic nature means that they have hydrophobic side which binds directly to lipids and hydrophilic side which are faced outwards. Lipids enveloped with bile salts are called micelles.
Formation of micelles increases the surface area of fat, which is appropriate for the the action of the enzyme pancreatic lipase (perform digestion of triglycerides).
Answer:
The uneven heating of Earth's surface produces wind because the air temperature and air pressure are different. The differences in the air causes the air to a lower pressure. ... Uneven heating of the Earth's surface produces air masses of different temperatures. Cold air sinks, forcing warm air to rise
ANSWER: B, killifish
REASONING: A secondary consumer consumes animals that eat only plants. Larvae and copepods do not fit these descriptions, because they do not eat animals. Snapper do eat animals, so do not fit the description either. Killifish eat small animals that do eat plants.
