What type of mutation is caused by radiation? Since this is a random process, such effects are now called stochastic. [100] Two important stochastic effects of radiation are cancer, which results from mutations in nongerm cells (termed somatic cells), and heritable changes, which result from mutations in germ cells (eggs and sperm). What is the […]

What are the factors that affect the rate of dissolution solution? There are three factors that affect the rate of dissolution: (1) the surface area of the solute, (2) the temperature of the solvent, and (3) the amount of agitation that occurs when the solute and the solvent are mixed. What increases the rate of […]

Can a person have zero mechanical energy? It is given that, momentum of the body is zero, it means the velocity of the body is zero. But Mechanical energy is the sum of kinetic energy and potential energy. So the kinetic energy of a body is equal to zero equals zero. So, even if the […]

What are the disadvantages of loop antenna? Following are the disadvantages of Loop Antenna: ➨Small loops have poor efficiency and hence are mainly used as receiving antenna at lower frequencies. ➨Small loop antennas have very low value of radiation resistance. This results into power loss as heat due to flow of current with high levels. […]

Why do waves travel faster in deeper water? As a wave enters deeper water the height and potential energy decrease. Therefore the speed of the wave must increase. Potential energy converted to kinetic energy. What do you think is the difference between shallow water waves and deep water waves? The distinction between deep and shallow […]

How can salt dissolve in water? Heat the water on a heating source such as a stove top or other burner. Salt will dissolve in room temperature or cold water as well, but heating the water speeds up the process. Place the rock salt into the warm water and allow it to settle. Does sea […]

Is 24 too old for medical school? The average age in US allo is about 24, and in DO is closer to 26-27. So no you wouldn’t be even close to too old. The oldest people in med school right now are in their 50s, I believe, although they are quite rare. There will be […]

What is the main function of the circulatory system in multicellular animals? Multicellular organisms have developed transport and circulatory systems to deliver oxygen and food to cells and remove carbon dioxide and metabolic wastes. Sponges are the simplest animals, yet even they have a transport system. What is the circulatory system in animals? The circulatory […]

Will the fossil record ever be complete? The fossil record certainly has gaps, mostly because the conditions required to create fossils have been rare ever since life began on Earth. A very small percentage of animals that have lived and died ever became fossils. Thus, many pieces of the puzzle are missing; some will never […]

What are the advantages and disadvantages of connecting bulbs in parallel and in series? Advantages and Disadvantages of a SERIES and PARALLEL circuit The current in the. circuit increases if more. Cells in series do not. last long. All circuit components. are controlled by one. If more bulbs are. added, the resistance. If one of […]
