Answer:
D) as we travel southward from the North Pole.
Explanation:
Species richness is the number of different species in a particular community. If we found 30 species in one community, and 300 species in another, the second community would have much higher species richness than the first.
Communities with the highest species richness tend to be found in areas near the equator, which have lots of solar energy (supporting high primary productivity), warm temperatures, large amounts of rainfall, and little seasonal change. Communities with the lowest species richness lie near the poles, which get less solar energy and are colder, drier, and less amenable to life. This pattern is illustrated below for mammalian species richness (species richness calculated only for mammal species, not for all species). Many other factors in addition to latitude can also affect a community's species-richness.
Cell division or reproduction process is called mitosis
Wind turbines rely on wind, which will continue to be available.
To organize microtubules and provide structure for the cell, as well as work to pull chromatids apart during cell division
Answer:
Vasodilation:
Vasodilation may be defined as the dilation of the blood capillaries around the skin. The blood capillaries gets widen. The vascular resistance to the blood flow decrease. The blood pressure near the skin decreases. The increase in temperature may cause vasodilation.
Vasoconstriction:
Vasoconstriction may be defined as the constriction of the blood capillaries around the skin. The blood capillaries gets narrow. The vascular resistance to the blood flow increases. The blood pressure near the skin increases. The decrease in temperature may cause vasoconstriction.
