Explanation:
Thats what an allergy is if you think about it
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.
Cheese, yogurt, buttermilk, sour cream, and pickles are lactic acid fermenters. Yogurt and cheese both start with a source of sugar (i.e., lactose from milk).

Answer:
Plastic is made from petroleum oil.
Explanation:
A faucet can simply be described as a tap or valve through which the releasing of a certain liquid can be controlled. Whereas a plastic is made from non-renewable resources such as petroleum oil. Also, the plastic cannot be properly degraded from the Earth after using it. Hence, drinking water from a faucet is more beneficial then drinking water from plastic bottles.
