What are multiple alleles give an example? Multiple alleles refer to the occurrence of three or more than three alleles for a particular gene. Alleles are different or contrasting forms of a gene. For example, for the gene encoding for height, one allele can be for tallness, whereas the other can be for dwarfness. What […]
What is it called when you replicate a study?
What is it called when you replicate a study? Replication is a term referring to the repetition of a research study, generally with different situations and different subjects, to determine if the basic findings of the original study can be applied to other participants and circumstances. What are the two types of replication psychology? At […]

Invite friends and family members to exercise with you. Plan social activities involving exercise. Develop new friendships with physically active people. What physical activity is the least expensive? Walking […]
Is energy released in alpha decay?
Is energy released in alpha decay? The energy released in this α decay is in the MeV range, about 106 times as great as typical chemical reaction energies, consistent with many previous discussions. Most of this energy becomes kinetic energy of the α particle (or 4He nucleus), which moves away at high speed. Is energy […]
What do you notice about the iron filings?
What do you notice about the iron filings? All magnets show properties of magnetic attraction and repulsion. With the use of iron filings, we can see these magnetic fields. When iron filings are sprinkled on a bar magnet, you see that these magnetic field lines start at the magnet’s north end and will end at […]
Do polar molecules have to be asymmetrical?
Do polar molecules have to be asymmetrical? Polar molecules MUST have an asymmetrical structure to be polar, because symmetry cancels out net charge. Asymmetrical molecules are always polar. Symmetrical molecules can be polar and non-polar. Polarity is dependent on the difference in electronegativity of the molecule’s atoms and shape. What is an example of asymmetrical? […]
What is the least common form of residence Pattern?
What are the two main barriers against implementing a renewable energy system?
What are the two main barriers against implementing a renewable energy system? The Siting and Transmission However, they can still present two primary barriers to renewables namely siting and transmission. What are the barriers in implementing alternative fuels? Alternative Fuel Vehicles Are Expensive. New technologies almost always require a high level of front-end capital investment. […]
Why is burning of candle is both physical and chemical change?
Why is burning of candle is both physical and chemical change? Wax of the candle is made of carbon and hydrogen which reacts with oxygen on burning and changes into carbon dioxide gas and water which escapes into the air. This is a chemical change. As a result, candle melts and reduces in size. This […]
Does current always flow in a loop?
Does current always flow in a loop? Current doesn’t have to flow in a loop, if something is losing charge (like an hot electron plate in space) the charge leaves and never comes back because the electrons boil off. Current is defined by amperes law you could imagine drawing a surface around the plate and […]
