Pls answer those question ​

Answer 1

Answer: 1. kidney

               2. Capillary

               3. Cooling effect

Explanation: 1. Blood, blood vessels and heart forms the circulatory system of an organism but kidney purifies the blood, so kidney is odd one.

          2. Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins). Superior vena cava and inferior vena cava are the two largest and longest veins of the human body and aorta is the largest and longest artery.

      3. Temperature, humidity and wind are all the factors affecting the climate. So, cooling effect is the odd one.
