Yes, protein can be considered a form of chemical energy because it contains stored energy in its molecular bonds. When broken down during digestion, proteins release amino acids, which can be used for energy production. However, carbohydrates and fats are more efficient energy sources. Proteins primarily build and repair tissues, but in emergencies (like starvation), the body converts them to energy. So, while not their main role, proteins do provide chemical energy.

The sun shines on everyone and everything—no favoritism here! It bathes the Earth in light, warming oceans, growing crops, and brightening your day. Whether you’re in Nigeria or Norway, rich or poor, the sun doesn’t pick sides. It’s a cosmic equalizer, giving life to plants, energy to solar panels, and tan lines to beachgoers. So next time you feel its rays, smile—you’re part of nature’s grand, glowing audience

A by-product is something extra produced while making something else. For example, when making cheese, whey is the by-product. It’s not the main goal but still useful. By-products can be sold, reused, or even recycled. They help reduce waste and add value. Think of sawdust from cutting wood—it’s not the main product but can be used for particleboard or fuel.

“Propensity” means a natural tendency or inclination to behave in a certain way. For example, someone might have a propensity for kindness or a propensity to procrastinate. It’s like an ingrained habit or preference. Think of it as a leaning toward something, whether in actions, choices, or traits.
