Answer:
Answer is false.
Explanation:
The pulmonary circuit can be described as the route through which deoxygenated blood moves away from the right ventricle of the heart to the lung, so that the blood can mix with oxygen, and become oxygenated blood.
This simply means that, the right side of the heart allows or moves the blood via pulmonary circuit , in order to be enriched with oxygen.
In this sense, it can be concluded that, the pulmonary circuit is supplied only by the right side of the heart.
Note that, the oxygenated blood from the lung follow systemic circuit. This means that the oxygenated blood move back to the left atrium and supply to parts of the body.
<span>The energy which we are using in today's world for our needs is fossil fuel, we used to power our home by burning coal and run our vehicle through the oil or fossil fuel, but we should know that it is limited in quantity and cannot use it once it releases energy or burned, it is created by the dead organic materials like trees and animals etc. which slowly buried in the ground as the time goes and after 1000's of years it get pressurised and rise in temperature make that organic material into fossil fuel, so that's how the fossil fuel comes in existence, which we extract from the ground by drilling deep into the ground.</span>
Common parts of a cell
The cell is the building block of an organism, its smallest living unit. By definition, all cells have the following:
<span>A cell membrane: As a barrier between the cell and its environment, the membrane provides structure, protection and control over the movement of materials in and out of the cell.Cytoplasm: This refers to the contents of the cell membrane excepting the nucleus. One of its main components is cytosol, a jelly-like substance which acts as protection and support for the remaining contents.<span>DNA: Each cell contains genetic material. However, the way it is stored is one of the distinguishing factors between a eukaryote (a plant or animal cell for example) and a prokaryote (like a bacterium). These represent the two main types of cells. The former has a nucleus — for its DNA — as well as other organelles while the latter does not. Organelles are parts of a cell that have a specialised function and their own membranes.</span></span><span>Nucleus</span>
