Though titanium is an extremely reactive metal, it is one of the most biocompatibile metals for the human body because Titanium alloys are less reactive than pure metal Titanium forms a stable oxide coating Titanium gets an insulatory covering by proteins Titanium does not react with anything in the human body In physiological conditions its reactions are inhibited (Question 1 of 10)2. Which of the following is false about Anabolic steroid use in athletes? ‘Stacking’ refers to taking different types of steroid at the same time. Anabolic steroids have no negative cardiac side effects but, it worsens liver diseases Athletes who use steroids can experience withdrawal symptoms when they quit ‘Cycling’ refers to dosing of steroid in cycles of weeks or months, with a short break between "Pyramiding," involves slowly increasing the number, the amount or the frequency of steroids to reach a peak and then gradually tapering the amount and frequency of the drug.(Question 2 of 10)3.
