<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

Dovator [93]

Answer:

Outcome variable (dependent variable)

Explanation:

In a scientific investigation, a DEPENDENT VARIABLE (also known as outcome variable) is the variable that is being measured. The dependent variable, as the name implies, responds to the changes made to the independent variable.

For example, in an experiment where the effects of different concentration of fertilizer is used to test plant growth (height), the HEIGHT OF THE PLANTS is the dependent variable because it is the variable being measured.
