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.
Reduce!<span> Buy and use less stuff. This is the best way to conserve natural resources. For example, it takes one ton of raw materials from the earth to make one laptop computer! We can also pay special attention to reducing the amount of non-renewable resources we use. For instance, by reducing our use of non-renewable oil and coal to give us energy and electricity, we can make less air pollution. Instead, we can get energy from the sun, the wind and the ocean's tides to heat our homes and light our rooms. These sources of renewable energy don't create pollution and they will never run out! We can also look for different natural resources to use so that we don't use up too much of one kind. For example, we can make tree-free paper out of plants like kenaf, bamboo, and hemp instead of trees! Using tree-free paper is much better for our forests and all the animals that depend on a healthy forest in order to survive.</span>
