Hormones circulate in blood transported throughout the body but affect only specific target cells because
a) specific cells have receptor proteins that bind with the molecule shape of the hormone
b) circulating blood vessels carry the hormones only to specific target cells
c) the "master gland", the pituitary, exercises control over target cells recognizing specific hormones
d) target cells contain enzymes that destroy all other competitive hormones

All the following are true to hormones except that hormones
a) end in "ase", and have a role in regulating cell processes
b) are chemical messages secreted directly into the blood stream
c) often affect target cells distant from the cells that secreted them
d) excite specific responses from target cells

I think this one is A but I don't know if it's a trick question

All the following are correct statements defining a hormone except
a) oxytocin travels in blood to mammary glands (breasts) to cause the secretion of milk
b) insulin enters the blood causing the liver to convert glucose into the storage molecule glycogen
c) acetylcholinesterase breaks ACh into acetate and choline molecules
d) insulin enters the blood making body cells more permeable to uptake glucose molecules
