1.Wear a laboratory garment and wellbeing goggles to secure your face and body 
- Take mind while conveying hardware 
- Tie long hair back 
- Dependably leave a Bunsen burner on the security fire (yellow) when it is not being used 
- Don't wear counterfeit nails as they are profoundly combustible 
- Do the test on a reasonable work area with nothing on it 
- Never take a seat while doing an analysis in the event that something spills would you be able to can't escape the route in time and it goes on you, causing you hurt 
- Tidy up everything suitably when teh explore is finished 
- Be mindful so as not to touch or get as of late warmed protests as they might be hot 
- Don't defile substances 
2.Triangle with exclamation point means General Warning
Triangle with a flame means Highly Flammable
Triangle with a zig zag arrow pointing down means Hgh Voltage
 

Most likely a is the answer - because  you generate   38 atp's but also consume an atp.   each atp gives approx. less than 4 kcal so probably a is the closest answer.
