Alex listed the typical steps of fossil formation. 1) an organism dies. 2) the remains fall to the bottom of the ocean. 3) the soft portions decay, and the hard portions remain. 4) the sediment becomes rock. which statement describes the missing step? after step 3, layers of sediment cover the dead organism. after step 1, minerals dissolve the dead organism. after step 4, layers of sediment cover the dead organism. after step 2, minerals dissolve the dead organism.

The answer is: After step 3, layers of sediment cover the dead organism.

Explanation:

Fossilization is the process by which living things are preserved as impressions on sedimentary rock (fossils). This is a rare process that occurs under the most appropriate conditions.

Process of Fossilization:

Permineralization is one of the most common types of fossilization. It involves the absorption of minerals into the remains, giving a detailed impression of the dead organism.

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.
