400
Describe one way that energy is lost between trophic levels in a food chain.
Energy is lost as heat during respiration or through waste
400
Explain the importance of water in maintaining the body’s metabolism
Water is essential for transporting nutrients, maintaining body temperature, aiding digestion, and facilitating biochemical reactions.
400
Explain why red blood cells do not contain a nucleus, and how this benefits their function.
Red blood cells lack a nucleus to provide more space for hemoglobin, allowing them to carry more oxygen.
