B. a = F – m
C. a = Fm
D. a = F divided by m
The answer is D. This means that is you have a determined amount of force (in newtons) being applied on an object of known mass (in kilograms), then to determine the acceleration of the object, divide the force by the mass (or multiplying the force with the inverse of the mass of the object). This behavior of objects is stipulated in Newtons/ second law. Increasing the force increases the acceleration while increasing the mass decreases the acceleration of the object. Acceleration is a vector quantity meaning it has magnitude and direction.
b. osmosis.
c. exocytosis.
d. phagocytosis.
The pericardium or pericardial sac is a membrane that surrounds the heart, consisting of the fibrous pericardium and the serous pericardium. The serous pericardium further has a parietal layer and a visceral layer or epicardium, which secretes a lubricating fluid.
The pericardium, also known as the pericardial sac, is a membrane that directly surrounds the heart and defines the pericardial cavity. It consists of two distinct sublayers: the sturdy outer fibrous pericardium and the inner serous pericardium. The fibrous pericardium, made of tough, dense connective tissue, protects the heart and maintains its position in the thorax. The serous pericardium has two layers, namely the parietal pericardium, which is fused to the fibrous pericardium, and an inner visceral pericardium, or epicardium, which is fused to the heart.
The macroscopic epicardium layer consists of a simple squamous epithelium called a mesothelium, reinforced with loose, irregular, or areolar connective tissue that attaches to the pericardium. This mesothelium secretes the lubricating serous fluid that fills the pericardial cavity and reduces friction as the heart contracts.
