A scientist wants to make a geologic column of rock layers from different parts of a state. Which claim explains how the scientist will do this? A. The scientist will organize the layers by comparing the fossils and types of rocks.

B. The scientist will measure the exact ages of the rocks found in each part of the state.

C. The scientists will look at the surface features in each area to organize the layers.

D. The scientist will select one area in the state and use only those layers to construct the geologic column.

A. The scientist will organize the layers by comparing the fossils and types of rocks.

Explanation:

A geologic column can be defined as a collection of rock layers that are typically grouped based on their relative ages in a descending order i.e from oldest to the youngest.

Generally, the layers of the rock that are found in various parts of the world are known to be different because they all comprises of distinct Earth's geological history.

In this scenario, a scientist wants to make a geologic column of rock layers from different parts of a state. Thus, the claim which best explains how the scientist will do this is that, the scientist will organize the layers by comparing the fossils and types of rocks.

Hence, the scientist will collect or gather the fossils obtained from various rocks located in different parts of the state and make a comparison.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;
