Question

the following scenario is fictional. if modern day humans lived in this fictional environment, which of the following traits would be most likely to human adaptations over time? (check all that apply)
*mountain planet (fictional scenario): on this planet, the only inhabitable territory is high up in the mountains. you may recall that there is les at higher altitudes. the terrain (earth) is very rocky and jagged, and the only source of food is small moss - like plants and goat - like creatures tha eaten for protein. the goat - like creatures are extremely strong and dangerous! however, they cannot see very well at night... they can be capt easily during the night time.
(check all that apply)
smooth feet and limbs that are easily cut/damaged
better vision in the evening and dark
more efficient blood cells that can deliver oxygen to muscles better
shorter arms that are adapted to fitting in small, narrow holes

Explanation:

1. Smooth feet and limbs that are easily cut/damaged: The terrain is rocky and jagged, so smooth, easily damaged limbs/feet would be a disadvantage, not an adaptation. So this is not selected.
2. Better vision in the evening and dark: The goat - like creatures can be captured easily at night, and humans would need to hunt them (or avoid them) at night. Better night vision would help in survival (hunting, avoiding danger), so this is an adaptation.
3. More efficient blood cells that can deliver oxygen to muscles better: The environment is at high altitudes where there is less oxygen. More efficient oxygen - carrying blood cells would help humans survive in low - oxygen, high - altitude conditions, so this is an adaptation.
4. Shorter arms that are adapted to fitting in small, narrow holes: There's no indication in the scenario that humans need to fit in small, narrow holes for survival (food, shelter, etc.). The main challenges are rocky terrain, high altitude, and hunting at night. So this trait is not related to the environmental challenges described, and is not an adaptation.

Answer:

• Better vision in the evening and dark
• More efficient blood cells that can deliver oxygen to muscles better
