What are the main causes of habitat destruction? Habitat destruction is the leading cause of biodiversity loss. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Why do animals die when […]
What happens when a big star collapses?
What happens when a big star collapses? The outer layers of the star will be ejected into space in a supernova explosion, leaving behind a collapsed star called a neutron star. Ordinary matter, the kind that we and everything around us is made of, is mostly empty. It is made up of atoms, which are […]
Why does black make me look thinner?
Why does black make me look thinner? This illusion could explain why we think black is more flattering than white; black shapes appear thinner than white shapes, possibly because the contours of black objects have more definition. A lighter color object will have lines, shapes, and perhaps partitions on it that are very visible to […]
Are any goods perfectly elastic?
Are any goods perfectly elastic? If demand is perfectly elastic, it means that at a certain price demand is infinite (A good with a very high elasticity of demand). In other words, if a firm increased the price by 1%, it would see all its demand evaporate. Is coffee elastic or inelastic? Availability of Substitutes […]
Will Vinegar float on water?
Will Vinegar float on water? They don’t mix in water and will float. Household vinegar consists almost entirely of water, but with some acetic acid molecules dissolved in it. Is isopropyl alcohol heavier than water? This means that water and isopropyl alcohol must have different densities and that the water is more dense than isopropyl […]

What is the difference between membrane potential and resting potential?
What is the difference between membrane potential and resting potential? For a cell’s membrane potential, the reference point is the outside of the cell. Because there is a potential difference across the cell membrane, the membrane is said to be polarized. If the membrane potential becomes more positive than it is at the resting potential, […]
Which one is the best example of law of conservation of mass?
Which one is the best example of law of conservation of mass? The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it […]
What role does carbon dioxide play in photosynthesis?
What role does carbon dioxide play in photosynthesis? The carbon dioxide enters the leaves of the plant through small pores called stomata. The plant uses sunlight as energy to perform this chemical reaction. Photosynthesis separates carbon dioxide and water — known as CO2 and H2O, respectively — into their individual molecules and combines them into […]
Do tents attract lightning?
Do tents attract lightning? Tents alone don’t attract lightning, but that doesn’t mean they’re safe during a thunderstorm. The possibility for a tent to get struck by lightning is increased by the campsite location and adjacent tall objects. What happens if lightning hits a tent? If a lightning bolt hits a tent the energy will […]
