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.
If a musician plays a wrong note, he will disrupt the harmony of rhythm of the song. This is because, he will be able to produce a sound of different wavelength which will cause a possible destructive interference with the waves being produced by his groupmates.
Answer:
You would need to save $300 every month to meet your savings goal.
Explanation:
4,500-900=3,600
3,600/12=300
Answer:
-16°C
Explanation:
PV = nRT
V and n are constant.
P / T = P / T
(2 atm + 1 atm) / (266 K) = (1.9 atm + 1 atm) / T
T = 257.1 K
T = -16°C
