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.
<span>Around 2.4 billion years ago, the first photosynthetic organisms appeared and used inorganic matter like carbon dioxide and water to produce glucose, with oxygen released in the atmosphere. Because of this, oxygen levels rose; this is called the <em>Great Oxygenation Event</em><span><em>.</em> Through time, photosynthetic organisms evolved to live in land (now as plants). As concentrations of oxygen in the atmosphere became higher, marine animals evolved to utilize oxygen readily available from the atmosphere (rather dissolved in water) hence the evolution of marine animals to land animals capable of respiration in land. </span></span>
The answer is <span>A) stimuli receiver, sensory neuron, central nervous system, motor neuron, muscle or gland.
Stimuli receiver receives an information. </span><span>The information is sent through a sensory neuron to the spinal cord, as a part of the central nervous system. </span><span>The spinal cord receives information from the body and relays it to the brain. It, then, receives information from the brain and relays it out through a motor neuron to the effectors (muscles or glands).</span>
So you want me to create environmental slogans or is this a question?
