Answer:
Explanation:
Total time of transfer oil fuel = 2.45 x 9 = 22.05 minutes
= 22.05 x 60
= 1323 s
Total volume of ful transferred = 687 gallon
= .0037854 x 687
= 2.6 m³
radius of pipe = .5 x 1.45 inch
= .5 x 1.45 x 2.54 x 10⁻² m
r = .018415 m
cross sectional area
= π r²
a = 3.14 x .018415²
= 10.648 x 10⁻⁴ m²
If v be the velocity
volume of fuel coming out a x v x t , a is cross sectional area , v is velocity and t is time .
10.648 x 10⁻⁴ x v x 1323 = 2.6
v = 1.845 m / s

Answer:
AQUAPORINS dramatically increases the rate of diffusion of water across cell membranes.
Explanation:
Aquaporins are integral membrane proteins also called water channels that forms pores in the membrane mainly for facilitating diffusion of water molecules in and out of the cell. Aquaporins selectively allow the passage of water molecules while preventing the passage of ions and other solutes through it as they are impermeable to protons, and large solutes. These proteins therefore increases the permeability of the membrane to water molecules and the rate of diffusion of water increases through them. Flow of water molecules in aquaporins follows the direction of osmotic pressure across the membrane. Aquaporins in some organisms have been modified to voltage gated aquaporins which helps them to close the water channels in unfavorable conditions such as drought and flooding. This is to prevent excessive loss of water to the surrounding or intake of water into the cells.
