What stories do some of the Romanesque metalwork pieces tell? What stories do some of the Romanesque metalwork pieces tell? Religious leaders being baptized. What is the major difference between Gothic and Romanesque architecture? Gothic architecture was mainly intended to make the churches look like heaven. The Gothic architecture made the churches bright, colorful, and […]

What is ionized helium? Singly ionized helium is an atom that has lost one of its electrons. We must expect its remaining electron to act like a hydrogen electron. There is only one difference between a hydrogen atom and a singly ionized helium atom; number of protons in the nucleus, so the nuclear charge. What […]

Can a person live without bone marrow? It is the blood cell ‘factory’. Healthy bone marrow releases blood cells into the bloodstream when they are mature and when required. Without bone marrow, our bodies could not produce the white cells we need to fight infection, the red blood cells we need to carry oxygen, and […]

How is glucose converted to ATP? Cells convert glucose to ATP in a process called cellular respiration. Cellular respiration: process of turning glucose into energy In the form of ATP. Does glycolysis occur in humans? Yes, glycolysis occurs in all the living cells including humans during cellular respiration. It is an essential process for generating […]

How do rocks and soil move downslope? Mass wasting – is movement in which bed rock, rock debris, or soil moves downslope in bulk, or as a mass, because of the pull of gravity. Landslides is a general term for the slow-to-very rapid descent of rock or soil. Flow – The debris is moving downslope […]

What is the total volume of the world? Total surface area of Earth is 510,082,000 sq. km. The oceans cover ~70.9%….Table 1. Volumes of the World’s Oceans from ETOPO1. Download Table 1 as a . PDF. North Atlantic Volume (km3) 146,000,000 % Ocean Volume 10.9 Avg. Depth (m) 3519 Max Depth (m) 8486 What percent […]

What is a wave cycle? Wave cycles are pairs of a maximum value and a corresponding minimum value. The crest front wavelength is the distance between the minimum and the maximum. A min2Max cycle is a pair of a local minimum and the following local maximum. Which is a characteristic of all waves? All kinds […]

How do rockets rotate? In flight, any rocket will rotate about its center of gravity, a point which is the average location of the mass of the rocket. Most rockets are symmetric about a line from the tip of the nose to the center of the nozzle exit. We will call this line the roll […]

Why do bats die near wind turbines? When a wind turbine’s blades move, they cause a drop in nearby air pressure. If a bat flies too close to a turbine, this drop in air pressure can damage its lungs. They found that each wind turbine kills around 5 birds and 12 bats every year! How […]
