1. 1

   What is the main reason performance falls at altitude?

   Resting heart rate falls sharplyLess oxygen reaches the working musclesBlood carries more carbon dioxideThe air is much hotter
2. 2

   What is the role of sweat on the skin?

   It raises core temperatureIt cools the body as it evaporatesIt keeps the skin warmIt blocks heat from the sun
3. 3

   What is the effect of vasoconstriction of skin arterioles?

   Faster sweat productionA fall in core temperatureLess heat lost from skinMore heat lost from skin
