Does facilitated diffusion transport oxygen? Facilitated diffusion. Some molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic core. In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. Why is facilitated diffusion faster […]
What is the use of direct shear test?
What is the use of direct shear test? A direct shear test is a laboratory or field test used by geotechnical engineers to measure the shear strength properties of soil or rock material, or of discontinuities in soil or rock masses. Why are direct shear box tests performed? The Direct Shear Test is an experimental […]
How does a constant speed propeller work?
How does a constant speed propeller work? Constant speed propellers work by varying the pitch of the propeller blades. As the blade angle is increased, it produces more lift (thrust). At the same time, more torque is required to spin the prop, and the engine slows down. What is the advantage of a constant speed […]

What is 3 bit synchronous counter?
What is 3 bit synchronous counter? The 3-bit Synchronous binary up counter contains three T flip-flops & one 2-input AND gate. All these flip-flops are negative edge triggered and the outputs of flip-flops change affect synchronously. The T inputs of first, second and third flip-flops are 1, Q0 & Q1Q0 respectively. How many flipflops are […]

What are the properties of a glass?
What are the properties of a glass? The main characteristics of glass are transparency, heat resistance, pressure and breakage resistance and chemical resistance. Is thicker glass a better insulator? Thick glass The thicker the glass, the better the sound insulation properties. The further the sound has to travel through the glass, the more sound waves […]
How do you calculate net worth?
How do you calculate net worth? Your net worth is what you own minus what you owe.
