Answer:
removal if metabolic waste
Explanation:
Answer: 2.3 g cm^3
Explanation: In this case the rise in level of water is same as the volume occupied by the stone.
a) Volume occupied by the stone = 70 cm^3 – 40 cm^3= 30 cm^3
b) Density = mass/volume
= 69g/30 cm^3 = 2.3 g cm^3
In energy processing systems electronic carrier molecules transfer electrons from one part to other part of energy processing system. This provides the necessary energy and reduces power to carry out chemical reactions. They are necessary for aerobic cellular respiration and photosynthesis.
