I just finished a topic in science on this.. lemme try my best:
4: PCR (Polymerase Chain Reaction)
5: Genetic Engineering
6: Restriction Enzymes (I think)
Let me know if I’m wrong!

Answer: The correct answers are 1) Endocytosis and 2) Receptors are specific for the cells.
White blood cells are specialized cells of the immune system. They play important role in protecting body from foreign agents like bacteria . For this, they recognize the bacteria and forms a covering around it, pinching off the vacuole. By this, the cell performs a process called as Endocytosis ( specifically phogocytosis).
The receptors present on the white blood cells are quite specific. Due to this, they recognize specific foreign particles. For example B- cells produce antibodies which bind to specific antigens ( foreign protein) and therefore mount specific immune response. In other words, specific foreign particles are recognized by specific white blood cell. This indicates that the receptors on these cells are specific.
Thus, the correct answer is 1) Endocytosis and 2) Receptors are specific for the cells.
