Can spinal nerve damage be repaired? The spinal cord rarely repairs itself when damaged, but ways of encouraging nerves to regrow are on the horizon. How serious is spinal cord compression? Without treatment, spinal cord compression can cause damage to the spinal nerves, which can result in loss of bladder or bowel control or paralysis. […]
Can science explain a rainbow?
Can science explain a rainbow? A rainbow is caused by sunlight and atmospheric conditions. Light enters a water droplet, slowing down and bending as it goes from air to denser water. The light reflects off the inside of the droplet, separating into its component wavelengths–or colors. When light exits the droplet, it makes a rainbow. […]
Which process is responsible for gas exchange in the lungs?
Which process is responsible for gas exchange in the lungs? External respiration is the exchange of gases with the external environment, and occurs in the alveoli of the lungs. Internal respiration is the exchange of gases with the internal environment, and occurs in the tissues. The actual exchange of gases occurs due to simple diffusion. […]
What is the reactants and products of photosynthesis?
What is the reactants and products of photosynthesis? Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive. What are the 3 reactants for photosynthesis What […]
What volume would 90 G occupy?
What happens if ammeter is connected in parallel?
What happens if ammeter is connected in parallel? Ammeter aims at measuring the current flowing through the circuit and hence, it is connected in series. When ammeter is connected in parallel to the circuit, net resistance of the circuit decreases. Hence more current is drawn from the battery, which damages the ammeter. Why is an […]
How much energy is produced by the combustion of methanol?
How much energy is produced by the combustion of methanol? Molar Heat of Combustion (molar enthalpy of combustion) of Some Common Substances Used as Fuels Substance (fuel) Molar Heat of Combustion (kJ mol-1) ΔHreaction (kJ mol-1) methanol (methyl alcohol) 726 ΔH = -726 ethanol (ethyl alcohol) 1368 ΔH = -1368 propan-1-ol (1-propanol) 2021 ΔH = […]
Why does Group 1 have the largest atomic radius?
Why does Group 1 have the largest atomic radius? Explanation: Every time we move down the group, the number of electron shells of the element increases by one. E.g. sodium has 3 electron shells, potassium has 4, rubidium has 5. Since the number of electron shells increase, the atom is getting larger and thus the […]
Which element is classified as a metalloid?
Which element is classified as a metalloid? The six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. Five elements are less frequently so classified: carbon, aluminium, selenium, polonium, and astatine. Is Si a Semimetal? 1 Answer. Silicon is a metalloid, also called a semimetal, which means it has properties of both metals […]
What is the meaning of normal distribution in statistics?
What is the meaning of normal distribution in statistics? A normal distribution is the proper term for a probability bell curve. In a normal distribution the mean is zero and the standard deviation is 1. It has zero skew and a kurtosis of 3. Normal distributions are symmetrical, but not all symmetrical distributions are normal. […]
