What are the three main pathways of ATP production? In general, the main energy source for cellular metabolism is glucose, which is catabolized in the three subsequent processes—glycolysis, tricarboxylic acid cycle (TCA or Krebs cycle), and finally oxidative phosphorylation—to produce ATP. What is the ATP CP system? The ATP-PC system uses a stored molecule in […]

What is C in binding energy? 12 C. This is the mass of the carbon atom, i.e. the mass of the nucleus plus the six electrons in the neutral carbon atom. Let’s calculate its binding energy. Why heavy nuclei are unstable? The presence of too many protons and neutrons in heavier nuclei will upset the […]

How do you slow down an egg drop? To slow down the egg, you need to increase the surface area – the larger the area, the more that air resistance acts against the egg. One effective way of doing this is to add a parachute, which increases the surface area significantly. Can cotton balls protect […]

Why is Aluminium foil a bad insulator? Aluminium foil is a great conductor of heat, which means it is a poor insulator when it is in direct contact with something hot. It is also so thin that heat can pass through it super easily when it has direct contact. This is they type of heat […]

What is the percent of 65 CU? 30.50% What are the two isotopes of boron? properties of boron mixture of two stable isotopes—boron-10 (19.9 percent) and boron-11 (80.1 percent); slight variations in this proportion produce a range of ±0.003 in the atomic weight. Why is boron-10 an isotope? Explanation: Isotopes are given by the name […]

What are the three steps that you can take to prepare for severe weather? -Collecting perishables such as canned meat, fruits, and water is a good idea in storm time. If the severe weather poses a threat to your power or water, it’s good to be prepared with plenty of food and water to get […]

What is the greatest use of groundwater? Irrigation accounts for the largest use of groundwater in the United States. Some 57.2 billion gallons of groundwater are used daily for agricultural irrigation from 475,796 wells. What is the primary cause of groundwater shortage quizlet? Ground water depletion is due to drying of wells, reduction od precipitation, […]

How far can electricity travel through power lines? As of 1980, the longest cost-effective distance for direct-current transmission was determined to be 7,000 kilometres (4,300 miles). For alternating current it was 4,000 kilometres (2,500 miles), though all transmission lines in use today are substantially shorter than this. Why does the current decrease when the voltage […]

What are the risks of infrared radiation? Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens. Other forms of damage to the eye from IR exposure include scotoma, which is a loss of vision due to the damage to the retina. Even low-level IR absorption can cause symptoms such as […]

How can we save water at home and school? Avoid flushing the toilet unnecessarily. Dispose of tissues, insects and other similar waste in the dustbins rather than the toilet. Landscape with native, drought tolerant plants, and mulch regularly. Raise awareness of the importance of water by creating colorful posters on water use and water saving. […]
