The cell wall is a structure only found in plants. It surrounds the cell and it provides protection, as well as gives it its structure and helps with filtering what goes in and out.

Answer:

According to my search:

Explanation:

The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.

Generally:

It protects the cell and prevents any physical damage.
It provides structure to the cell. It prevents osmotic bursting.
It protects the protoplasm against mechanical injury.

Each ABO blood group is associated with the presence/absence of RBC antigens and the presence/absence of antibodies in the plasm

harina [27]

Answer:

a. Type O blood - No A or B antigens on RBCs-Anti-A antibodies in plasma-Anti-B antibodies in plasma

b. Type A blood - A antigen on RBCs- Anti-B antibodies in plasma

c. Type B blood - B antigen on RBCs- Anti-A antibodies in plasma

d. Type AB blood - A antigen on RBCs- B antigen on RBCs- Neither anti-A or anti-B in plasma

Explanation:

ABO blood grouping system represents multiple allelism which was discovered in humans by Karl Landsteiner. The blood group is determined by the presence or absence of A & B antigens and antibodies.

The 4 blood groups which exist in ABO system are O, A, B and AB. Also, allele A and B are co-dominant i.e. if they both will exist on the surface of an RBC then both will be equally expressed which implies that there will be no dominant or recessive allele.

Type O blood group has H antigen on the surface of RBC and has both the antibodies i.e. antibody A and B. The absence of antigens A and B makes it a universal donor.

Type A blood group has A antigen on RBC and has antibody B in the plasma.

Type B blood group has B antigen on RBC and has antibody A in the plasma.

Type AB blood group has both the antigens i.e. antigen A and B on RBC and does not have any antibody in the plasma which makes it a universal acceptor.
