Killer whales are one of the top predators in the sea. They tend to eat almost anything that they come across, their diet depending on exactly what is living in their home waters. They are known to eat fish, squid, seals, sea lions, penguins, and even other whales, such as sperm whales.ou can thank the Greeks and the Romans for the name Orca, and the early Spanish sailors for the term Killer Whale. Ancient Romans originally applied the name Orca to these animals, possibly borrowing it from the Greek opue. One other thing, they are not really whales, but a type of dolphin.
A person with genotype AB has type AB blood, and a person with genotype OO has type O blood. A person with type A blood cannot receive type B blood. The reason is immunological. A person with type A blood does not have type B antigens; thus, his immune system considers the type B antigen to be foreign and attacks it.A person with type A blood can't receive type AB blood, either, for the same reason. He can, however, accept type O blood. person with type A blood cannot receive type B blood. The reason is immunological. A person with type A blood does not have type B antigens; thus, his immune system considers the type B antigen to be foreign and attacks it.
* A cat with type A phenotype may have the genotype AA (homozygous i.e. non-carrier) or the genotype Ab (heterozygous i.e. carrier). * A cat with type B phenotype can only be genotype bb (homozygous). The inheritance and full implications of the rare AB blood type is not yet understood.Note that Ab means a blood-type A cat carrying the recessive b gene and is different from a blood-type AB cat. Blood type B is shown by upper case B.ype AB cats are rare. Ideally, they should receive blood from a type A donor. They can receive type B blood, but as type AB cats potentially have Anti-B alloantibodies, this may result in premature destruction of the type B red cells in donated blood.
