Humans, like other organisms, require energy for growth and repair. When cells create ATP for energy, carbon dioxide is produced as a waste product. How does the body respond to this process in order to maintain homeostasis? A. The digestive and respiratory systems interact to move carbon dioxide to the lower intestine, where it is transformed into
methane.
В. The nervous and urinary systems interact to move carbon dioxide to the kidneys, where it is absorbed into the
bloodstream.
C. The circulatory and digestive systems interact to move carbon dioxide to the stomach, where it helps to break down food.
D The circulatory and respiratory systems interact to transport carbon dioxide to the lungs, where it is expelled from the
body.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
