Answer:
to maintain homeostasis these things must be controlled:
- pH levels in the body (I.e. the stomach)
- wanted levels
- sugar levels
- level of Co2 in our bodies
- blood glucose levels
- body temperature
we maintain homeostasis to ensure that our enzymes, which speed up or make chemical reactions are working well and work within he required conditions.
external things we can do to maintain homeostasis:
- wearing the appropriate clothing in summer and winter
- consuming the correct temperature beverages (i.e. cold drinks in summer)
- consumitn the correct temperature and nutrient required foods (I.e. nutritious pumpkin soup in winter)
we also shiver when we are cold - the friction between our muscles produces heat.
Answer:
Reproductive isolation
Explanation:
The definition of speciation is "the formation of new and distinct species in the course of evolution." Because a new a distinct species is formed, even if not physically isolated, they can not interbreed because two species can not reproduce with each other. Therefore, the answer is Reproductive isolation, because speciation will still occur even without physical isolation.
