Answer:
- <u>Cell has a limited supply of NAD+</u>
Explanation:
Cellular respiration occurs in the cytoplasm, where glucose is broken down for energy processing. Energy is produced by aerobic respiration in the presence of oxygen, whereas anaerobic respiration can be carried out in an oxygen-deprived environment.
Fermentation is one kind of anaerobic respiration- here, the cells use glucose to generate a Net 2 molecules of ATP from the 6carbon sugar. Glucose is first converted to pyruvate, which is oxidized in a complex process. While 4 ATP are produced in fermentation, 2ATP are used in regenerating NAD+ from NADH2.
Two types of fermentation include lactic acid fermentation and alcoholic fermentation. These occur in single-celled, and multicellular microbes.
Granite is a type of intrusive igneous rock
Explanation:
An igneous rock formed from hot magma or lava cools, solidifies or crystallizes to form rocks.
Based on the rate of cooling of magma, igneous rocks can either be intrusive or extrusive.
A slow cooling of the magma deep within the earth without reaching the surface of the volcano leads to the production of intrusive igneous rocks.
This slow cooling leads to crystallization forming large crystals visible to the eyes with a phaneritic texture.
Granite has the best phaneritic texture among intrusive igneous rocks. Granite crystals can be easily visualized and are constituted by minerals like white feldspar, black hornblende, translucent quartz, and platy black biotite.
Extrusive igneous rocks like basalt are formed from microscopic crystals from fast cooling of magma.

Answer:
as I know
Explanation:
<em>Igneous rocks, which form from cooling magma or lava, and metamorphic rocks, which have been altered by heat and pressure, are unlikely to contain fossils. The “soft” tissues of an organism, such as skin, muscles, and internal organs are typically not preserved as fossils.</em>
