B. Every ecosystem has weather
The correct answer is - D) I and II.
When a fossil is found, one of the most important things that need to be looked at are the location where the fossil was found and how deep the in the ground the fossil was found.
The location of the place where the fossil is found is important as it can provide us with information about the environment of where the fossil lived, the geography of the place, was it land or water. Since reconstructions of the geological past have already been made, an experienced paleontologist will manage to use it without any problem.
How deep is the fossil found is also very important. The reason for that is that certain layer in the ground is a part of certain geological eon, era, period... By looking at the layer in which the fossil has been found we can relatively easily come to an information about its relative age.
<h2>Pericardium </h2>
Explanation:
Pericardium is the fibrous tissue that surrounds the heart and the roots of the great blood vessels
The pericardium's outer coat is called the parietal pericardium which is tough and thickened, loosely cloaks the heart, and is attached to the central part of the diaphragm and the back of the breastbone
Its inner coat is called the visceral pericardium or epicardium which is double, with one layer closely adherent to the heart and the other lining the inner surface of the outer coat
The intervening space between these layers is filled with pericardial fluid
This small amount of fluid acts as a lubricant to allow normal heart movement within the chest
Answer:
The primary structure of a protein - its amino acid sequence - drives the folding and intermolecular bonding of the linear amino acid chain,which ultimately determines the protein 's unique three-dimensional shape.
