1.they pump blood to all body organs so ventricles need thick walls whereas atria pump blood only to lungs so it does not need thick walls
2.the zigzag movement in the alimentary canal is known as peristaltic movement.
3. bcoz the take up carbondioxide at night and prepare an intermediate which is acted upon by the energy absorbed during the day.
4.The law implies that the heat produced in a resistor is
H=I^2RT
-directly proportional to the square of current for a given resistor
-directly proportional to the resistance for agiven current
-directly proportional to the time
hope this helps!!☺
and btw I'm also in 10th.....All the best for the board exams!!
