Your body creates chemical energy from the food you eat, which contains carbohydrates, lipids, and proteins. These are large molecules that first need to be broken down into simpler molecules, such as monosaccharides, C6H12O6; fatty acids, C14H28O2; and amino acids, C2H5NO2. Of these molecules, which has the greatest supply of hydrogen atoms per molecule? Which is the most reduced in terms of having the least number of oxygen atoms per carbon atom? Which can react with the most oxygen molecules to produce the most energy? Which provides the most dietary Calories per gram?

- Consider a man who has 20 kg of body fat when he goes on a hunger strike. Determine how long he can survive on his body fat alonearrow_forwardSpace aliens visited you last night and left you with a "present". They left behind a liter of shimmering blue substance. This substance is liquid at room temperature, but when you place it in a refrigerator it turns to a shimmering blue solid. When you take it back out of the refrigerator, it turns into a shimmering blue liquid again. What kind of change (chemical or physical) most likely occurred? Explain why to support your answer. Use evidence from the text to support your answer.arrow_forwardWhich scenario is an example of a negative feedback loop? When body temperature increases, sweat is produced as a cooling agent to lower body temperature. When body temperature increases, sweat is produced as a cooling agent to lower body temperature. In some parts of the world, birth rates are far exceeding death rates, which has led to overpopulation. In some parts of the world, birth rates are far exceeding death rates, which has led to overpopulation. Ice reflects sunlight much better than water. A warmer atmosphere is turning ice to water, which is absorbing more of the Sun’s energy. Ice reflects sunlight much better than water. A warmer atmosphere is turning ice to water, which is absorbing more of the Sun’s energy. A warmer atmosphere is leading to warmer oceans. A warm ocean releases more carbon dioxide, which traps more heat in Earth’s atmosphere. A warmer atmosphere is leading to warmer oceans.

- Did you ever seen a nanomaterial? What is it and what material did you used?arrow_forwardhow can a corn kernel go from a hard seed to fluffy popcorn we eat?arrow_forwardYazid wants to make compost from leaves, sawdust, and food scraps. Leaves have 2% N, C:N 22.5, and MC 77%. Sawdust has 30% C, C:N 300, and MC 20%, whereas food scraps have 2% N, C:N 20, and 50% MC. If the amount of leaves used is 15 kg, determine how much food scraps and sawdust should be added to get a compost mixture with an ideal ratio of C:N 30:1 and moisture content 60%?arrow_forward
- Chemical Engineers are actively involved in the production of sunscreens. Given your knowledge in Chemistry and Physics, why do we need to apply sunscreens? Is it necessary that the sunscreen should be broad spectrum?arrow_forwardsorry for the misunderstanding sir/ma'am ...it stated biology instead of physics im really sorry.sir/ma'am Can u please help me with this?sir/ma'amarrow_forward: P Note: You may assume you have an excess of either reactant if the reaction requires more than one of those molecules to form the products. In the drawing area below, draw the skeletal ("line") structures of the missing organic products X and Y. You may draw the structures in any arrangement that you like, so long as they aren't touching. H+ H+ + -OH ☑ Y Predict the organic products that form in the reaction below: Click and drag to start drawing a structure.arrow_forward
- H.W: How many nanocubes can you get if you break the cube with 1 m on each side into 1 nm length? What is the collective surface area of the nanocubes? Answer: (No. = 1027, Total SA = 6 x 10° m2 = 6000 km?)arrow_forwardSmall birds like that in (Figure 1) can migrate over long distances without feeding, storing energy mostly as fat rather than carbohydrate. Fat is a good form of energy storage because it provides the most energy per unit mass: 1.00 grams of fat provides about 9.40 (food) Calories, compared to 4.20 (food) Calories per 1.00 grams of carbohydrate. Remember that Calories associated with food, which are always capitalized, are not exactly the same as calories used in physics or chemistry, even though they have the same name. More specifically, one food Calorie is equal to 1000 calories of mechanical work or 4184 joules. Therefore, in this problem use the conversion factor 1 Cal = 4184 J. Figure 1 of 1 Part A Consider a bird that flies at an average speed of 10.7 m/s and releases energy from its body fat reserves at an average rate of 3.70 W (this rate represents the power consumption of the bird). Assume that the bird consumes 4.00 g of fat to fly over a distance do without stopping for…arrow_forwardSmall birds like that in (Figure 1) can migrate over long distances without feeding, storing energy mostly as fat rather than carbohydrate.
