Adult siblings are much more likely to act out toward each-other all the hurt, anger and frustration that really should be directed toward their parents. Instead of being there for their siblings, they become alienated, adversarial or […]

Do wind chimes keep birds away? Do Wind Chimes Keep Birds Away? Any unusual or unexpected noises do work to keep birds away, but as soon as they get used to the noise, they’ll likely return. Placing wind chimes in your yard may yield temporary results, but it’s unlikely that it will work for years […]

What is the difference between centripetal acceleration and centrifugal force? The centripetal acceleration is the acceleration a body experiences in centripetal motion (moving in a circle or along an arc). On the other hand, the centrifugal force is a fictitious (imaginary) force the object experiences during circular motion. Why does centripetal force work? As the […]

What four possible gametes are formed from an individual? There are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, […]

What is evidence of longshore drift? The transport of sand and pebbles along the coast is called longshore drift. The prevailing wind (the direction the wind ususally blows from) causes waves to approach the coast at an angle. The swash carries the sand and pebbles up the beach at the same angle (usually 45º). What […]

What are the 4 types of vegetation? Scientists divide the Earth’s land into what are called vegetation regions. These areas have distinct types of plants, soil, and weather patterns. Vegetation regions can be divided into five major types: forest, grassland, tundra, desert, and ice sheet. How is vegetation related to climate? Vegetation can affect climate […]

Is temperature a energy? Temperature is a measure of the average kinetic energy of the atoms or molecules in the system. The water molecules in a cup of hot coffee have a higher average kinetic energy than the water molecules in a cup of iced tea, which also means they are moving at a higher […]

Is a human an Autotroph? The short answer to it is no, humans are not autotrophs. All entities are broadly classified into one of the two categories – autotrophs (ones who make their own food) and heterotrophs (one who cannot produce its own food and depends on others for its nutritional requirements). What is an […]

Which is a man-made element? All elements with atomic numbers 1 through 94 occur naturally at least in trace quantities, but the following elements are often produced through synthesis. Technetium, promethium, astatine, neptunium, and plutonium were discovered through synthesis before being found in nature. Is technetium man-made? Technetium was actually discovered — produced artificially — […]
