Answer:
Aquaporins acts as water channels that conduct water to and fro cell membrane during osmosis
Explanation:
Osmosis is a type of cellular transport in which water moves from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane. The osmotic process occurs with the aid of selective protein channels called AQUAPORINS. They allow only the passage of water and prevent that of ions and solutes.
Aquaporins help in the osmotic process by creating a channel for the passage of water molecules across the membrane. In other words, aquaporins facilitate the speedy movement of water molecules across membranes via osmosis, which is normally slow due to the POLARITY OF WATER MOLECULES.
Answer:
your arteries that are connected to your lungs are also connected to your heart and then you need to be in the vena cava which are connected to your heart as well so you need the veins
Answer:
The mitochondria are called the powerhouses of the cell, where ATP is produced. It is composed of an inner membrane called cristae, and an outer membrane that covers the organelle.
The cell wall is a rigid structure made from(in the case of plant cells rather than bacteria or fungi) cellulose and other rigid fibers.
The cell membrane is a fluid, thinner structure made up of a double layer of phospholipids which are comprised of the hydrophilic heads facing outwards and hydrophobic tails facing toward each other in the layer.
The nucleus has protons, and neutrons that are contained within it, and electrons around it.
