Answer: Temperature control
Explanation:
Arterio-venous anastomoses (AVAs) are direct connections between small arteries and small veins. In humans they are numerous in the glabrous skin of the hands and feet.
They are very significant in body temperature control. These temperature control are under the dual control of the central nervous system and the local thermal influence. While the arteriovenous anastomoses control the skin temperature through volume changes in the superficial venous bed, the arterioles and capillaries operate by generalized dilatation which results both in increased temperature and in redness of the skin.
Answer:
Extraction of oil from tar sands is not economically feasible.
Explanation:
Dissolved O2 conc. in flask with algae will be higher since photosynthesis produces O2.
Answer: studies indicate that humans living in warm, tropical environments (from a variety of populations) tend to have noses that are wider at the base because inhaling warm, moist air does not require adaptations.
