I found the full exercise on the internet. Attached is an image of the characteristics and the types of muscle fibres.
Fast twitch:
- few mitochondria (most of the energy comes from acid lactic fermentation)
- low myoglobin content (O2 is not used as the main source of energy)
- shorter twitches
- anaerobic (uses mainly glucose and no O2)
- easily fatigued (as soon as glucose storage finishes fatigue comes in)
- high glycogen content (glucose as the main source of energy and therefore more glucose storage in the form of glycogen)
Slow twitch:
- high myoglobin content (energy comes from O2 and therefore is needed much myoglobin)
- aerobic (uses O2)
- low glycogen content (as O2 is the main source of energy, glucose is not needed as much)
-longer twitches
Answer:
Air inside the guard hairs traps heat close to the body, keeping the reindeer warm even in the frigid, windy temperatures of the tundra. The guard hairs also prevent body heat from escaping and melting the snow if the reindeer lies down, keeping it from getting wet and cold.
Wild animal attacks should qualify as biological disasters rather than geological disasters.
Disasters generally refer to accidents that happen rather suddenly and result in widespread damages or loss of lives
- Biological disasters are disasters whose causes have biological origins such as plants, animals, humans, and microbes.
- Geographical disasters are caused by natural geographical events such as landslides, cyclones, hurricanes, volcanic eruptions, and so on.
Wild animals are biological organisms, hence, an attack from them would be a biological disaster.
