Answer:
Explanation:
LPG gas is basically propane and butane, and it is odourless in its natural state. The smell that you notice when there is a leak is actually the stench of an entirely different agent, called Ethyl Mercaptan (C2H6S). This substance is added to the gas when it leaves the main storage terminals.
Answer:
Parasympathetic nervous system effects are slow or inhibit function, where is sympathetic, is responsible for the intense physical activity.
Explanation:
The autonomic nervous system or ANS is divided into 2 distinct systems on the basis of their effects- the parasympathetic nervous system and the sympathetic nervous system.
Both of these have opposite actions on the functions that they maintain.
The sympathetic nervous system regulates the body for a high level of physical activity and also known as fight or flight. It fasts the functions of the body according to the situation.
The parasympathetic nervous system is having the opposite effect of the sympathetic nervous system slows high energy functions and relaxes the body.
Thus, the comparison of these nervous systems is mention above.
Answer:
Phase III
Explanation:
The given condition fall in the trial phase (Phase III) of cinical study which aims to:
- Determine drug's effectiveness (primary goal)
- Determine long-term drug safety
- Confirm findings
In Phase III, randomised, double-blind, placebo-controlled, parallel group study is majorly to evaluate the efficacy and safety of placebo in episodic migraine prevention in children (6 to < 12 years of age) and adolescents (12 to < 18 years of age).
The trial consists of four phases: screening; double-blind therapy period for 24 weeks in which placebo or Erenumab is given to subject as dose 1, dose 2 or dose 3 (based on the participant's body weight) once a month via subcutaneous injection; optional dose level blinded extension phase (40 weeks) which involves subjects recieve dose1, 2 and 3 of placebo, and at last it follows a safety follow-up phase for 12 weeks (after 16 weeks of the last dose of investigational drug).
Hence, the clinical phase is phase III.
