Symptoms Distinctive facial features, including small eyes, an exceptionally thin upper lip, a short, upturned nose, and a smooth skin surface between the nose and upper lip. Deformities of joints, limbs and fingers. Slow physical growth before and after birth. Vision difficulties or hearing problems. […]
What are the 5 sources of heat energy?
What are the 5 sources of heat energy? Here are only some of your many choices for heating energy sources: natural gas, propane (LP), oil, coal, wood, electricity, heat pumps, ground source heat pumps and solar energy. Why sound is important in our daily life? Everything we know is founded upon the human body’s ability […]
What is the difference between the continental drift hypothesis and the tectonic plate theory?
What is the difference between the continental drift hypothesis and the tectonic plate theory? Plate tectonics explains why Earth’s continents are moving; the theory of continental drift did not provide an explanation. Therefore, the theory of plate tectonics is more complete. What happens if continents collide? Continental collision is a phenomenon of the plate tectonics […]
Which F Cl Br is most stable?
Which F Cl Br is most stable? Generally, the singlet is less stable as the triplet has half-filled orbitals which lead to stability. However, whenever a group that can give electrons, they stabilize the singlet by back donation of their lone pair into the vacant orbital of the singlet carbon. Why is Cl more acidic […]
Why do we use microwave for communication?
Why do we use microwave for communication? Uses. Microwaves are widely used for point-to-point communications because their small wavelength allows conveniently-sized antennas to direct them in narrow beams, which can be pointed directly at the receiving antenna. What type of information can be sent by microwaves? Microwaves are used mostly for point-to-point communications systems to […]
Are false lashes bad for you?
Are false lashes bad for you? Unfortunately, fake eyelashes may also cause temporary or permanent loss of your real eyelashes. Taking the fake lashes off can break your natural lashes, and even damage the hair follicle. When this happens, your own lashes can fail to grow back. How do you get eyelash extensions off without […]
Which of the following is paramagnetic N2?
Which of the following is paramagnetic N2? The electronic configuration of boron has been shown which tells us that it is paramagnetic. Same applies to nitrous oxide. Is N2+ more stable than N2? Bond order of both N2+ and N2- is 2.5, but according the molecular orbital theory, N2- has more antibonding electrons than N2+. […]
Which force helps swimmers float in water?
Which force helps swimmers float in water? Buoyancy Why is it better for a swimmer to be higher in the water? Wave resistance will be reduced proportionally by any amount of water that can go over the top of the swimmer. This is the reason why swimmers progress better underwater (at approximately a depth of […]
Is smoking once a month OK?
Is smoking once a month OK? A person who smokes one or two cigarettes a few times a month may be less likely to trigger a full-blown addiction to nicotine. However, they are playing with fire by introducing this highly addictive substance into their bodies. Will 1 cigarette a week harm you? Simon Chapman, Emeritus […]
Why do we need energy to remove an electron?
Why do we need energy to remove an electron? The energy needed to remove an electron from a neutral atom is the ionization energy of that atom. It is easier to remove electrons from atoms with a small ionization energy, so they will form cations more often in chemical reactions. What would happen if an […]
