Sea slugs often have very bright coloration. One species varies from bright yellow to light green to neon blue. This species of slug happens to live in a coral reef dominated by bright yellow sea whips and blue brain coral. The green slugs stand out to predators and are eaten more often than the blue or yellow slugs. What are the extreme traits? What is the middle trait? What trait(s) are being selected for? What trait(s) are being selected against? What type of natural selection in occurring? What would happen to the sea slug population if this coral reef was overgrown by green algae that killed all the sea whips and brain coral

the answer is "a.) well–developed vascular system."

explanation:

lunar landing mission. apollo 11 was the first manned mission to land on the moon. the first steps by humans on another planetary body were taken by neil armstrong and buzz aldrin on july 20, 1969. the astronauts also returned to earth the first samples from another planetary body.

explanation:

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
