B)underwater
Explanation:
Judging by the presence of limestone in the Ordovician rocks, we can conclude that the ancient Indiana was once being underwater.
The fossils found in a rock are very good indicators of the paleoclimatic conditions in an area.
Since we have an abundance of rich marine organisms, then the area must have been under a vast expanse of ocean water.

The process that occurs in the mitochondria is cellular respiration. It is on the cristae that cellular respiration occurs, where food is converted into another usable form of energy. Most of the energy producing reaction which occur in the mitochondria, happens in the surface of the cristae.
It can replace, repair or be a new type of cell to benefit the host.
Cellular differentiation occurs throughout the cell development of a multi-cellular organism. It occurs when the cell changes from a simply zygote into a complex system of tissues and cell types.
<span>Stems cells are cells which have the potential to develop into many different cell types in the body during early life and growth. Stem cells serve as internal repair system in many tissues. When stem cells divide while undergoing cell differentiation, it can either retain being a stem cell or become another type of cell like muscle cell, brain cell, or red blood cell.<span> </span></span>
Answer: protein conformation has been destroyed due to heat
Explanation:
Proteins are made up of several polypeptide chains linked by hydrogen bonds, and peptide bonds among their amino acids subunits.
At elevated temperatures, the hydrogen and peptide bonds are cleaved resulting in change in conformation of the protein. At this point, cooling DOES NOT renature the protein, as its bonds have been broken.
