Scientists have a theory about the relationship between climate and biodiversity. Which best describes this theory? Warmer climates promote higher biodiversity, allowing plants to grow year-round. This supports more organisms that rely on plants. Colder climates promote higher biodiversity, reducing the competition among organisms for food. This supports stronger organisms that live longer. Warmer climates promote higher biodiversity because they tend to receive more rainfall. This provides a source of water for more organisms. Colder climates promote higher biodiversity because they are usually larger in size. This provides space for more organisms.

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.

i'm thinking (a) to keep sand in place; ////////////

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
