14. (a) The diagram shows how blood glucose in mammalian body is regulated. Rise Normal glucose Level 90mg/100cm (i) Name the hormone R Fall Pancrease secretes hormone R Less hormone R secreted Hormone Z released Z Fall Rise Normal glucose Level 90mg/100cm (1mk) (1mk) (ii) (2mks) (b) (i) Suppose there is failure of the pancrease to secrete hormone R in a person. Name the disease the person would suffer from and state how it can be treated. Disease (2mks) State two ways by which hormone R lowers glucose level in the blood when it rises above 90mg/100cm. Treatment (ii) Name the organ which produces hormone Z. (c) (i) Define term homeostasis (ii) State two ways by which mammalian blood carry out homeostasis function. (1mk) (1mk) (2mks)
