What are the four main classes of macromolecules? The four major classes of biological macromolecules are carbohydrates, lipids, proteins, and nucleic acids. In what organisms are starch and glycogen found? Starch (a polymer of glucose) is used as a storage polysaccharide in plants, being found in the form of both amylose and the branched amylopectin. […]
What prompts an engineer to improve world?
What prompts an engineer to improve world? But what prompts an engineer to improve our world? Well, they solve problems. Problems are an engineer’s inspiration, and maths and science are the creative tools they use to solve them. A mechanical engineer designed the engine, a mechatronics engineer devised that controls. How have engineers changed the […]

Why do oil and water that mixed together separate into layers?
Why do oil and water that mixed together separate into layers? The water molecules attract each other, and the oil molecules stick together. That causes oil and water to form two separate layers. Water molecules pack closer together, so they sink to the bottom, leaving oil sitting on top of the water. Why do you […]
What does it look like in a black hole?
What does it look like in a black hole? Black holes have gravitational fields so strong that even light cannot escape, so they are defined by the shell of a black, featureless sphere called an event horizon. But the holes can nevertheless be seen. As they consume matter that strays too close, they squeeze it […]
What is the total energy particles in a material?
What is the total energy particles in a material? Thermal energy measures the total kinetic energy of the particles in a substance. The greater the motion of particles, the higher a substance’s temperature and thermal energy. A substance’s total thermal energy depends on its temperature, number of atoms, and physical state. Is kinetic energy same […]
What stage are seeds formed?
What stage are seeds formed? Seeds are the product of the ripened ovule, after fertilization by pollen and some growth within the mother plant. The embryo is developed from the zygote and the seed coat from the integuments of the ovule. How fruits and seeds are formed Class 7? Fruits and Seed Formation After fertilisation, […]
Do living organisms obey the second law of thermodynamics?
Do living organisms obey the second law of thermodynamics? Human organisms are not a closed system and thus the energy input and output of an the organism is not relevant to the second law of thermodynamics directly. No The Second Law of thermodynamics applies in the truest sense to closed systems. Living systems can not […]
What are the 5 steps of long division?
What are the 5 steps of long division? It follows the same steps as that of long division, namely, – divide, multiply, subtract, bring down and repeat or find the remainder. Here’s an example of long division with decimals. 123454321 when divided by 11111 gives a quotient of 11111 and remainder 0. What is the […]
