Summary Introduction
To explain:
The health risks and immorality associated with the consumption of anabolic steroids in sports.
Concept introduction:
Steroids are organic compounds (lipids) with four rings. The sex hormones found in the humans are steroids. Anabolic steroids are androgen-based steroids. They increase the protein level in the cells. Thus, help in muscle development and performance enhancement.

b) Many bio-chemical processes in the human body must remain at equilibrium to sustain life. At times,
some situations cause the disturbance to the natural equilibrium causing serious health issues or even
death.

- The following questions apply to this information:A man licks a newt after being dared to do so by his boyfriend. Almost immediately, the man noticed that his lips and tongue felt numb. Within a few minutes, the man began to show a lack of coordination and skeletal muscle control. Within several more minutes, the man experienced difficulty breathing and symptoms of cardiac arrest. Eventually, the man dies. The newt's skin has tetrodotoxin in it. Tetrodotoxin is produced by rough-skinned newts as a form of defense against predation. Tetrodotoxin specifically blocks the sodium pore in voltage-gated sodium channels. It does not affect the gates of a voltage-gated sodium channel. The toxin has no other effects.We will use one bipolar neuron to answer the following questions. This neuron has a resting membrane potential of -65mV. 1) true/false While under the effect of tetrodotoxin, the man's neurons would be able to reach threshold potential at their initial segments. 2) true/false The…arrow_forwardWhat is the result of damage to relative biological effectiveness?arrow_forwardWhich option is not true?

- Disclaimer : The last item is number 5arrow_forwardAn athlete tested positive for Methylhexaneamine in urine with a level of 0.90 µg/mL. At her appeal in the Court of Arbitration, she quotes a highly respected scientific publication that states that at levels of 1.0 µg/mL there is no performance enhancement. If the athlete’s levels are indeed below this threshold, the athlete can face a year’s suspension instead of a ban for life. Use the Estimate of Uncertainty to determine if the Athlete should be given a 1 year suspension or banned for life.arrow_forwardYou are visiting A nurse in a foreign country the doctor orders heparin 50 Units kilograms dose subcutaneously daily (50 units/kg*dose*day)) The patient weighs 100 pounds heparin is supplied in a vial that reads 5000 units per milliliter how many milliliters will you administer in three daysarrow_forward
