Which is a difference between proteins and carbohydrates and fats?
morpeh [17]

Answer:

HERE JUST TAKE IT

Explanation:

Ok, there's carbon and hydrogen in all of them, that's the only similarity. They are known collectively as macro-nutrients.

Carbohydrates are basically, oxygen, carbon and hydrogen and they're the bodies primary source of energy. This means that they're the first source of energy used which is why if you eat foods high in simple sugars you get a sugar rush. All carbs metabolize down to glucose, some faster than others.

Fats are called lipids. Lipids are very heterogeneous (this means that there's not much similarity between them). Some examples of lipids are steroids, seed oils, pork fat, cholesterol, etc. The main thing in common with them is that they don't mix with water. They are readily stored in fat cells in the form of tryglicerides and are used when carbs are all used up. They also yield the highest per gram amount of energy (it escapes me right now).

In a chemical sense, fats are lipids derived from animals (saturated, solid at room temperature) and oils are derived from plants and seeds (insaturated with some exceptions, and liquid at room temperature. Insaturated are healthier because they contain HDL which cleans your arteries (prevents artherosclerosis).

Proteins are made up of aminoacids, 20 make up the vast amount of human proteins. Enzimes (the most famous being digestive enzimes) are proteins, skin is covered in protein, hair is protein, cilia and flagella are protein, basically EVERYTHING is protein, after water the human body is basically protein. They're only used up as energy when everything else is used up.

When athletes eat/drink protein, it's to give them building materials in order to increase the amount of stuff inside their cells which will enable them to produce more energy.

What is one way a plain can form?
ryzh [129]

Answer:

A. Erosion from wind, water, or ice removes crustal material.

Explanation:

Plain formation can occur in many different ways some plates some planes can form as wind, water and ice erode wear away or remove dirt and rocks on higher land.

Wind picks up and carries along small particles which can be abrasive against surfaces, slowly wearing them away to form more particles. The water and ice transport the fragments of rock and dirt as sediment down hillsides, where it is eventually deposited. This occurs until several layers of sediment are accumulated. Plains can also form at the bases of mountains where water carries a flow of sentiments downhill to flat areas where it further spreads out to deposit the sediment in a fan shape -this is called an alluvial plain.
