Some of the carbon dioxide is transported dissolved in the plasma. Some carbon dioxide is transported as carbaminohemoglobin. However, most carbon dioxide is transported as bicarbonate. As blood flows through the tissues, carbon dioxide diffuses into red blood cells, where it is converted into bicarbonate.
Answer:
The correct answer is A from an area of higher concentration to an area of lower concentration
Explanation:
Diffusion is one of the most important membrane transport process which helps in the transport of small molecules and gases across the plasma membrane from higher concentration region to the region of low concentration until the concentration of the transported molecule becomes equal at both sides.
As the molecule move along the concentration gradient no external energy is needed to carry out simple diffusion.
Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
