Select the correct answer Current is conducted thru the gel by electrons which move away from the negative electrode and towards the pos electrode O If the power supply voltage is fixed increasing the resistance of the gel increases the current that flows through it O Decreasing the power supply voltage increases the resistance of the gel O Choose this answer if none of the statements is true O If the power supply voltage is fixed Increasing the length of the gel will decrease the current flowing through it

The cross-sectional area of a fiber made out of flax swells as a result of absorbing its allowed maximum amount of water. Calculate the final area (swollen) in μm^2 of a fiber that has an initial dry equivalent diameter of 13.3 μm .

What is the role of lysozyme and a low ionic strength extraction buffer? Select all that apply. Cells absorb water from a low ionic strength extraction buffer, by osmosis, swell and lyse, releasing their contents Lysozyme breaks down bonds in the cellulose cell wall of plants, weakening the structure Cells release water into a low ionic strength extraction buffer by osmosis, shrink and lyse, releasing their contents Lysozyme is an enzyme found in lysosomes in cells Lysozyme breaks down bonds in the peptidoglycan cell wall of bacteria, weakening the structure Lysozyme is an antibiotic found in tears, saliva, human milk and mucus.

Can you please answer this question and say the correct letter

Of the choices below, pick the answer that best characterises pulsatile flow: O In pulsatile flow, red blood cells must deform to pass through blood vessels. Pulsatile flow is is primarily dependent on a fluid's potential energy The continuity equations cannot be applied to pulsatile flow O Pulsatile flow is dominant in large blood vessels such as arteries leading directly from the heart. Pulsatile flow must take turbulence into account.
