The dark areas on the map show the distribution of coral reefs around the world. What explanation best describes why the distribution of coral reefs is limited to the areas shown on the map? A. Competition for space is lowest in waters along the equator.
B. Equatorial waters provide some of the clearest water for symbiotic algae to produce energy.
C. Predation is lowest in areas along the equator because of increased rates of decomposition.
D. The corals need the strong water currents found here in order to find sufficient mates.

Sediment layers stop lateral spreading when: they encounter a barrier they encounter an opposing current they run out of additional sedimentary material

Diffusion and osmosis are forms of passive transport

What is the difference between sex-linked traits and autosomal traits in humans? a. sex-linked traits can only be passed from fathers to sons, while autosomal traits can be passed on from both parents to offspring of any sex. b. sex-linked traits are passed on through the x and y chromosomes, while autosomal traits are passed on through the other 22 chromosomes. c. sex-linked traits only affect females, while autosomal traits affect both males and females. d. sex-linked traits refer to genes that are on the x and y chromosomes, while autosomal traits refer to genes on all 23 chromosomes.
