B. theory
if many people perform the experiment and conclude the same things/ come to the same results, the hypothesis then becomes a theory. A theory is an idea that is widely accepted as true, but not 100% proven factual (ex: the theory of gravity)
Answer:
d. The species diversity of plot 2 is greater than that of plot 1.
Explanation:
Species diversity of an area depends on its species richness and species evenness. Species richness is the number of species present in that area. Species evenness measures how evenly these species are distributed.
Here, both plot 1 and plot 2 have same number of species. They both have four species of trees ( maple, birch, oak and pine) hence their species richness is same. However plot 1 has 85% maple trees and the rest three species make the remaining 15%. Plot 2 has more even distribution as 35% of trees are maple trees and birch and oak also have similar frequency with 25% and 35% respectively. Hence, plot 2 has more evenness.
Species diversity depends on both richness and evenness. Since plot 1 and 2 have same richness but plot 2 has more evenness, plot 2 has more species diversity than plot 1.
1. D is the answer. Sun's radiation hits the equator the hardest.
2. B. The definition of doldrums is a low activity period in time or area. So, that's your answer.
3. B. The Coriolis effect deflects air to the right in the northern hemisphere.
You would expect to find that as the generations pass, the offspring of the Bone-gnawers would have short, wide mouths and strong chewing muscles. The Non-gnawers would have longer, narrower mouths, and weaker chewing muscles. This is because the offspring would inherit the parent's traits, and this would lead to eventual less genetic diversity as the two groups of coyotes inbred more and more. (Sorry if I went further than needed, just trying to be thorough! I really hope that this helps!)
