What is a high pressure system and what kind of weather does it bring?

Hi there!

A high pressure system is when the pressure is high which is associated with nice weather (i.e sunny, warm, etc). When the pressure in air is high, the air is sinking which will cause less moisture or water droplets, meaning a smaller chance or precipitation.

Hope this helps!

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.
