A
Explanation:
Pulmonary vein carries oxygenated blood from the lungs to the left atrium of the heart. Before this, the heart pumps deoxygenated blood to the lungs through the pulmonary artery. In the lungs, this blood expels carbon IV oxide and takes up oxygen. Haemoglobin in the Red Blood Cells is responsible for this. In the heart, this oxygenated blood is pumped by the left ventricle to the rest of the body through the aorta artery. This oxygen is significant in cellular respiration in tissues.
Answer :
Vinegar is a weak acid. This is used to make a naked egg. When an egg is added in the vinegar for one day / 24 hrs, it reacts with the eggshell. The calcium carbonate shell gets dissolve.
Then an egg without shell is formed and the size of the egg does not change. The calcium carbonate reacts with acetic acid and forms carbon dioxide.
When the shell-less egg is kept in the vinegar for 48 hrs i.e. 2 days again, the water content in it enters into the eggs through the membrane. Then the egg gets somewhat bigger.
Otherwise, for 24 hrs, vinegar is acting like an isotonic solution and only dissolves the shell. This experiment would be done for showing the osmosis process through the cell membrane.
