Answer:
Yes, our body is made up of four Macromolecules.
Explanation:
Yes, the claim of the student is right that Macromolecules such as carbohydrates, lipids, proteins, and nucleic acids makeup the human body because all the cells are made up of carbohydrates, lipids, proteins, and nucleic acids. We know that our body is made up of cells so we can say that our body is made up of four Macromolecules. For example, our muscles are made up of protein, the fats present in our body are the lipids, carbohydrates are stored in the form of glycogen In liver and nucleic acids are present in the form of DNA and RNA.
This energy most directly results from the life activity of respiration.
The hummingbirds have very high energy expenditure (have the highest oxygen requirements of all vertebrae) with a fast heart rate, very fast wing beats and sustained hovering. So the hummingbird is nearly always on the edge of starvation, needing to take in more nectar than its body weight each day.
The respiratory system of these birds is highly adapted for the high oxygen needs. So, the muscles of the hummingbird cause pressure changes within the air sacs. As a result, more oxygen can enter the respiratory system. Also, they have the highest density of red blood cells which allows them to rise heart beat to around 500 breaths per minute during flight.
Answer:
natural gas is the largest source of energy in US .

Answer:the stored energy is in form of carbohydrates stored in photosynthetic plants. This is consumed by higher organisms such as man & animals. In these higher organisms, the energy in form of ATP is used for work & activities. Other higher organisms then feed on smaller once such that energy is transferred within the ecosystem. Some of this energy is also lost in the form of heat because the conversion process is not 100% efficient. There is therefore energy balance in the ecosystem.
