A) bind to receptors in the nucleus of their target cells.
Explanation:
Steroid hormones are synthesized from cholesterol and are lipids, therefore they cannot be transported in the blood dissolved in the plasma. They are associated with transport proteins to travel in blood.

Answer:
Azithromycin will be in your system for <u>around 15.5 days</u>, after the last dose.
Explanation:
Azithromycin has an elimination half-life of 68 hours. The prolonged terminal half-life is thought to be due to extensive uptake and subsequent release of drug from tissues. It takes around 5.5 x elimination half life's for a medicine to be out of your system. Therefore it would take 374 hours about 15.5 days (5.5 x 68 hours) for it to be eliminated from the system. So it'll be in your system for that period of time, after the last dose.
