Why do metamorphic rocks rarely contain fossils? A.
These rocks are formed underwater, and the water dissolves the fossils.
B.
The rock formation occurs from extremely hot magma deep inside the crust where organisms do not live.
C.
These rocks undergo extremely high pressure or temperature changes when formed, which would destroy fossils.
D.
These rocks are usually formed from extremely hot magma or with severe lava explosions, which would destroy fossils.

If you live in the southern hemisphere, what season would you be experiencing in position C this diagram?

Hm.

Explanation:

Igneous rocks form from molten rock, and rarely have fossils in them. ... Metamorphic rocks have been put under great pressure, heated, squashed, or stretched, and fossils do not usually survive these extreme conditions. Generally, it is only sedimentary rocks that contain fossils.

So the answer is C.

the trilobite is used as an index fossil for various geologic time periods as specific types of the trilobites were present in different geological time periods. they are a group of marine arthropods belonging to the class of trilobita.

explanation:

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.
