Is the cell membrane fully permeable? The cell wall is fully permeable to smaller molecules with the size of 30-60 kDa. The membrane is selectively permeable and controls the movement of the substance into and outside the cell. Functions include protection from the external environment. Do animal cells have a selectively permeable membrane? Cell Membranes. […]
Why do transmission lines use High Voltage?
Why do transmission lines use High Voltage? The primary reason that power is transmitted at high voltages is to increase efficiency. The lower current that accompanies high voltage transmission reduces resistance in the conductors as electricity flows along the cables. This means that thin, light-weight wires can be used in long-distance transmission. What happens to […]

What is wrong with the evolution?
What is wrong with the evolution? Evolution could be falsified by many conceivable lines of evidence, such as: the fossil record showing no change over time, confirmation that mutations are prevented from accumulating in a population, or. observations of organisms being created supernaturally or spontaneously. Why evolution is possible? Populations evolve. Because individuals in a […]
What is difference between primary and secondary?
What is difference between primary and secondary? Primary sources are first-hand accounts of a topic while secondary sources are any account of something that is not a primary source. Published research, newspaper articles, and other media are typical secondary sources. What is one difference between primary and secondary sources? Primary sources can be described as […]
What is mean by apparent movement of sun?
What is mean by apparent movement of sun? The apparent motion of the sun, caused by the rotation of the Earth about its axis, changes the angle at which the direct component of light will strike the Earth. From a fixed location on Earth, the sun appears to move throughout the sky. What causes apparent […]
How did Robert Wilson discover microwaves?
How did Robert Wilson discover microwaves? The Large Horn Antenna and the Discovery of Cosmic Microwave Background Radiation. Bell Labs radio astronomers Arno Penzias and Robert Wilson were using a large horn antenna in 1964 and 1965 to map signals from the Milky Way, when they serendipitously discovered the CMB. What were Penzias and Wilson […]
Is cornflour the same as corn starch?
Is cornflour the same as corn starch? Corn flour is made by finely grinding whole corn kernels, whereas cornstarch is made just from the starchy part of corn. As a result, corn flour contains protein, fiber, starch, vitamins, and minerals, whereas cornstarch is mostly carbs….Processing. Cornstarch Corn flour Carbs 28 grams 22 grams Fiber 0 […]
