A frog heart has 3 chambers, 1 ventricle and 2 atria. One atrium (the right) receives deoxygenated blood from the frog's body (in the systemic circulation) and then pumped to the single ventricle wherein it will go to the lungs to be oxygenated. Another atrium (the left) received oxygenated blood from the lungs then pumped to the single ventricle wherein it will go to the systemic circulation. In the single ventricle, some form of mixing of the oxygenated and deoxygenated blood happens but since the frog is a cold blooded animal, the decrease in the concentration of oxygen is deemed superficial.
This advancement allows the frog to live on land using the lungs as the primary organ for oxygenation of the blood.
The answer would be A!!!!
cubic <span>meter (m^3) is the symbol for volume</span>
1. through sweating where the body is cooled down by the sweat released from the body through the skin pores.
2.Through urinating where the body releases excess water and absorbed food particles so as to cool down the body
The answer is true. The Species-Area Curve lets us to forecast how many species will keep on if the forest is reduced in size by a stated amount. The y-axis specifies how many species can be preserved in an exact area while the x-axis specifies the area of habitat.
