Why is burning coal bad for the environment?
Why is burning coal bad for the environment? The burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change.

How do you make a sucrose density gradient?
How do you make a sucrose density gradient? Sucrose density gradient solutions Prepare 150 mL of 1X PE buffer containing 0.1% (w/v) Triton X-100. Prepare the sucrose solutions: To prepare a 20% (w/w) solution: i. Zero a container on a balance. ii. Add 10 g sucrose to the container. iii. Add the PE/Triton solution slowly […]
What happens if the magnetic field flips?
What happens if the magnetic field flips? During an excursion or a reversal, the magnetic field is considerably weakened and allows many more cosmic rays to reach the surface of the planet. These energetic particles from space can be damaging to life on Earth if too many reach the surface. How often do poles reverse […]
Why is a neutral object attracted to a negatively charged object?
Why is a neutral object attracted to a negatively charged object? Neutral object are attracted to either charge. The region that has too many electrons is negatively charged, the other region positively, because of lack of electrons. The positive region since it is closer to the charge will be attracted to this charge. This process […]
What is difference between space and orbit?
What is difference between space and orbit? What’s the difference between ‘outer space’ and ‘orbit’? Answer: Outer space begins somewhere around 1,200 miles above the Earth. Orbit occurs when an object’s momentum perpendicular to the Earth’s surface creates sufficient centrifugal force to counteract Earth’s gravity. Is rocket science actually hard?
