in blood circulation the blood passes twice through the heart to supply once to the body. next it helps in fulfilling the energy needs of the warm blooded animals having the high rate of metabolism.
1st statement is correct while 2nd point is incorrect
mark as it's help full
OPTION = D.Open Circulation
Blood have 4 parts,namely,Red blood cells,White blood cells,plasma and platelets. Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response.The tree types of blood vessels are ,veins, arteries and capillariessee the attachments

Double circulation is the circulation in which blood travels twice through the heart in one complete cycle of body
It is found only in mammals as they r the organim with high energy requirements
#they need more energy because they are warm blooded.

DOUBLE AND SINGLE CIRCULATION
Deoxygenated blood from the body tissues is poured into right atrium. Contraction of heart forces it into right ventricle. From right ventricle deoxygenated blood flows to the lungs through pulmonary artery.oxygenated blood from lungs is return into left atrium and then into left ventricle. The left ventricle forces the oxygenated blood to the whole body.thus, for making one complete round of circulation circuit around all body parts, the blood passes through the heart twice.
the pathway of blood from heart to the lungs and back to the heart is called pulmonary circulationand the pathway of blood from heart to the body and back to hurt is called system circulation this is known as double circulation of blood
you take the atomic mass of calcium over the atomic mass of
and multiply it by 100 to get the percentage.
the mass of
is 40.078 g; the mass of
is 12.01 g, and the mass of
is 47.997 g (
add all the masses together to get a total mass of 100.085 g.
0.4004 or 40.04 %
tu line segment is parallel to rs line segment because of 32/36 = 40/45.
the theorem related to side splitter interprets that if a line is parallel to a definite side of a triangle and happen to intersect the other two sides, then line bisects those two sides in a definite proportion.
each intersection, to be equal, in that case, the lines becomes parallel.
the second is if the alternate internal angles, the angles that are located on opposite sides of the transversal and are located inside the parallel lines, are equal, then the lines become parallel.
