Answer:
A taxonomy map of philosophy is created using 5 layer version
Explanation:
The map is drawn in a circular form, the parent is usually the center and then the child or the sub branches are then made around the first- parent circle to show the relation between the parent and its child. These branches can have their own sub branches which are then included around the branches the child of the original parent.
During nitrogen fixation, bacteria breaks nitrogen gasses down into a usable form for plants.
Answer:
<em>The correct option is A) The cell theory is the result of explanations of scientists' observations and not a description of the cell structure as it relates to the function.</em>
Explanation:
The cell theory can never become a law because Scientific theories are well-tested explanations, while laws are well-tested descriptions of natural phenomena; one cannot become the other.
A scientific theory is subjected to be changed overtime but a law cannot change. We have observed many changes in the cell theory in the past and we might find changes in this theory in the future also. Hence, the cell theory can never become a law.
Answer:
The Mitral/Bicuspid Valve
Explanation:
The heart is composed of 4 chambers: left and right atria, and left and right ventricles. The “right heart” (right atrium and ventricle) receives deoxygenated blood from the systemic circulation through the Vena Cava, and impels this blood towards the lungs through the Pulmonary Arteries where it will be oxygenated. The “left heart” (left atrium and left ventricle) receives oxygenated blood from the pulmonary circulation through the Pulmonary veins and impels this blood towards the systemic circulation through the Aorta artery.
The systemic and pulmonary circuits work in series, and maintaining the unidirectional course of the blood flow is very important. This can be done by the presence of fibrous valves that are present between the atrium and the ventricles, and in between the ventricles and the Pulmonary/Aorta artery.
The location of these structures are as follows:
Systemic circulation ⇒ Right Atrium → [Tricuspid Valve] → Right Ventricle → [Pulmonary Valve] → Pulmonary Artery ⇒ Pulmonary circulation
Pulmonary circulation ⇒ Left Atrium → [Mitral/Bicuspid Valve] → Left Ventricle → [Aortic Valve] → Aorta ⇒ Systemic circulation
