What is needed for an ecosystem to support the greatest variety of organisms? Answer: An ecosystem must contain producers, consumers, decomposers, and dead and inorganic matter. All ecosystems require energy from an external source – this is usually the sun. Plants need sunlight to photosynthesize and produce glucose, providing an energy source for other organisms. […]
Why can you not fart in space?
Why can you not fart in space? The lack of gravity in space means the air in astronauts’ stomachs doesn’t separate from ingested food, so burping could expel more than just gas. Spaceflight missions also avoid serving high-flatulence foods, like Brussels sprouts and cabbage, to avoid “flammable butt gas” that’s hazardous in pressurized cabins. What […]
What evidence does the fossil record provide?
What evidence does the fossil record provide? Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet’s history. They can also help scientists reconstruct the evolutionary histories of present-day species. Why are fossils so hard to find? Fossils are rare because their formation and […]
Why the motion of pendulum will not be a simple harmonic motion?
Why the motion of pendulum will not be a simple harmonic motion? Any pendulum undergoes simple harmonic motion when the amplitude of oscillation is small. The pendulum still oscillates, but the motion is no longer simple harmonic motion because the angular acceleration is not proportional to the negative of the angular displacement. Why is the […]
Who is the father of atom?
Who is the father of atom? Basic Atomic Structure. The idea that everything is made of atoms was pioneered by John Dalton (1766-1844) in a book he published in 1808. He is sometimes called the “father” of atomic theory, but judging from this photo on the right “grandfather” might be a better term. How thick […]
Do convection heaters use a lot of electricity?
Do convection heaters use a lot of electricity? Gas heaters are generally a little cheaper to run than electricity heaters. Convection gas heaters draw in the cold air and heats it up using a gas-powered element. It then evenly disperses this heat throughout the room. A convection-radiant element is similar, however the element is slightly […]

What do you mean by impedance matching?
What do you mean by impedance matching? The term “impedance matching” is rather straightforward. It’s simply defined as the process of making one impedance look like another. Frequently, it becomes necessary to match a load impedance to the source or internal impedance of a driving source. What is impedance simple words? The definition of an […]
What is the intensity for muscular endurance?
What is the intensity for muscular endurance? For experienced lifters who want to improve their muscular strength, aim for 8–12 reps per set for 2–4 sets, with a 2- to 3-minute rest between sets. To improve your muscular endurance, do 15–20 repetitions at no more than 50% of your 1RM, with a 2- to 3-minute […]
What are some of the examples of exceptions to the patterns of our solar system?
What are some of the examples of exceptions to the patterns of our solar system? Exceptions to the rules: The generally orderly solar system also has some notable exceptions. For example, among the inner planets only earth has a large moon, and Uranus is tipped on it’s side. A successful theory must make allowances for […]
