Answer:
2.compare a layer at one location to layers at other locations
Explanation:
Comparing rock layers in distant places can be a challenge for geologists since these layers may have different environmental factors that caused different transformations in them.
Therefore, when it is necessary to establish a comparison between layers of rocks in different ligands, geologists must establish steps to make an efficient comparison and have results consistent with reality. To do this, they must first compare a layer in one location with layers in other locations, assign relative age to a layer in one location, and identify index fossils in one or more layers in one location.
Remnant of a structure that may have had an important function in a species' ancestors, but has no clear function in the modern species.
<h2>Two pieces of information </h2>
Sonar is an instrument which is used to search for things which are underwater. It is also used to find the depth of water by giving out ultrasonic vibrations into the water. The time which the vibrations take to return assists to find the distance of the reflecting surface.
The correct answer is bioavailability.
<span>Bioavailability is an important factor in establishing nutrient requirements and it represents the degree to which food nutrients are available for absorption and utilization in the body. The amount of a nutrient in a food that the body can actually use may vary depending on age and physiologic condition.</span>
Answer:
Most enzymes are proteins and therefore their function is specific to their structure. Enzymes function as a catalyst to increase the rate of virtually all the chemical reactions that take place in a living system.
