Vasoconstriction is an adaptation for survival because by restricting the blood flow to your “periphery” the more warm blood gets pumped to your vital organs keeping them alive, for example you might get frostbite on your fingers and toes because they are non essential, but your organs will be okay because the warm blood is keeping them from turning to ice. Humans adapted this way to survive in cold climates.
Answer:
Increase in plant and animal diversity
Explanation
Grassland biomes are bigger in size , rolling terrains of flowers, grasses and herbs.Soil, Latitude and local climates mostly determine the type and amount of vegetation growing in the grassland.
A grassland is a region where the average annual precipitation is great enough to support grasses, and in some areas a few trees. Research study was conducted in which increased precipitation was strongly linked with the plant diversity, biomass, plant available Nitrogen. This is because grasslands contain a specific type of precipitation patterns that supports the survival of some plants but not others, So if the precipitation is increased more organisms can survive, like those which cannot survive in normal conditions, which consequently enhances the diversity of plants and animals in grasslands.

This is because the electrons are up around the oxygen more than they are around the hydrogen. The electrons are spinning around but they're around the oxygen more than they are around the hydrogen. This makes them polar because they have a charge on one end of the molecule. In a nonpolar molecule electrons are evenly distributed.
Answer:
Emotion is an organism's response to a stimulus that includes a mixture of physiological arousal, expressive behaviors, and conscious experience.
Explanation:
What is an Emotion?
Emotion is a neural drive that moves a living organism to action, provoking automatic reactive behavior that has been adapted through evolution as an survival mechanism to meet a survival need. In simple words we can say that Emotion is a mental state related with the central nervous system, several chemical messengers released in neural signal transmissions are responsible for different emotions like happiness, sadness, difference in thoughts etc
