Answer;
The fibrous pericardium is not distensible, which causes the blood to put pressure on the heart, constricting it and reducing its ability to contract
Explanation;
-Cardiac tamponade is a clinical syndrome caused by the accumulation of fluid in the pericardial space, resulting in reduced ventricular filling and subsequent hemodynamic compromise.
-The most common causes of cardiac tamponade are; rupture of an aortic aneurysm (a bulge in the wall of the aorta), advanced lung cancer, acute pericarditis (inflammation of the pericardium), a heart attack, and heart surgery.
The options attached to the question above are given below:
A. All living and nonliving things consist of one or more cells.
B. Cells and living organisms are spontaneously created.
C. Cells are the most complex unit of structure and function in living things.
D. A cell is the basic unit of structure and function of all organisms
ANSWER
The correct option is D.
The cell theory is one of the major theories in biology and it states the facts about living cells. The theory states that, the cell is the most basic unit of all organisms and all living organisms are made up of one or more cells. The organisms that are made up of only one cell are described as unicellular while those that possess many cells are described as multi cellular. The theory also states that all cells come from pre-existing cells.
the correct answer is d

Answer:
The correct answer is option b."Ecosystem diversity".
Explanation:
Ecosystem diversity is a term used to describe the variations of abiotic and biotic conditions that could be present within a geographical location. This type of diversity is characteristic of species that live in different ecological habitats, such as deserts, forests, oceans, steppe, among others. For instance, rats are small mammals that have adapted to live in most habitats in the world.
