In biology, diffusion is the movement of substances with the concentration gradient, which means they move from an area of high concentration to an area of low concentration. Facilitated diffusion is diffusion that is performed with the help of a carrier protein that can move particles of the substance.

An organism must has a large surface area to volume ratio in order to exchange material easier
in animals erythrocytes have a flat concave shape that allows them to carry more haemoglobin and also increases its surface area to volume ration so that the length and availability of a surface is less for the materials to travel
multi cellular organisms tend to have flat and elongated respiratory surfaces to allow for a higher surface area to volume ratio in order to increase the rate of gas exchange
the ilium in most mammals is flat and elongated and is covered with microvilli to increase surface area and to reduce the cells volume therefore reducing its surface area to volume ratio

Neutrophils is sign of body infection.If you have high neutrophils which is present in human blood then its is known as Neutophilia.
Its a type of white blood cells (WBC) its an important part of immune system which helps body to fights with infection. When micro organisms such as bacteria or viruses are enter in human body then these neutrophils are the first immune cells to respond.
Under normal conditions, the number of neutrophils in healthy person is between 2,500 to 6,000 .If neutrophils are increases of deceases in human body then doctor suggested antibodies.It may eventually go away, or remain as a life - long condition.

Answer:
It is technically possible, if and only if, both parents have AO and BO blood.
Explanation:
the only way (most of the time) a child can get O blood is if both genes accepted by the parents are O. That would mean both parents would have to have O recessive genes.
