Insulin whereas glucagon Decreases blood glucose concentrat
     Insulin _____whereas glucagon _____  Decreases blood glucose concentration; increases blood glucose concentration.  Increases blood glucose concentration; decreases blood glucose concentration.  Removes blood glucose with urine; retains blood glucose in bloodstream.  Retains blood glucose in bloodstream; removes blood glucose with urine.  Decomposes glucose to H_2O and CO_2; builds glucose molecules from H_2O and CO_2.  As a rule, hormone secretion is controlled through:  Positive feedback mechanism\'  Negative feedback mechanism.  Reflex loop mechanism.  It is produced by the demand of local organs.  It doesn\'t controlled, endocrine gland produces hormone all the time when it is active.  Which hormone exerts its effect primarily upon the reproductive organs?  Antidiuretic Hormone (ADH).  Follicle-stimulating Hormone (FSH).  Prolactin-releasing Factor (PRF).  Adrenocorticotropic Hormone (ACTH).  Norepinephrine.  Which of the following is secreted by the neuro-secretory fibers at posterior pituitary?  Thyroid-stimulating Hormone (TSH).  Adrenocorticotropic Hormone (ACTH).  Luteinizing Hormone (LH).  Oxytocin.  Follicle-stimulating Hormone (FSH).  Calcium concentration in body fluids is under the control of two endocrine glands:  Hypothalamus and Anterior Pituitary.  Anterior and Posterior Pituitary.  Thyroid and Parathyroid.  Adrenal cortex and Adrenal medulla.  Pancreas and Pineal.  Chemical messengers released by endocrine glands to regulate some functions of other cells are known as:  Electrolytes.  Neurotransmitters.  Antibodies.  Hormones.  Pheromones. 
  
  Solution
Thanks for the question.
29. Answer is A. Insulin secretion is inversely proportional to the levels of glucose.
30.C. The control of hormone secretion is regulated by the blood levels of the hormone.
31.B.It regulates growth and reproductive functions in the body.
