Answer:
A. Phytoplankton
Explanation:
They as producers contribute the most. Others do too, but not as much.
Answer:
Adaptive evolution
Explanation:
The radiation of finches in the Galápagos archipelago is the result of the natural selection process described by Darwin as adaptive evolution. Evolution is the process for which the organisms better adapted to its environment have more chances to survive and to reproduce, thereby leaving more offspring in the next generation.
Moreover, adaptive evolution refers to the mechanism for which species evolve by the emergence of advantageous mutations that are fixed through positive selection, thereby favoring the phenotypes that have higher adaptive fitness.
Answer:
The answer is the crossing over between chromossomes is reciprocal.
Explanation:
Crossing over between chromossomes is reciprocal, so whenever a recombinant chromosome of one type is produced, there is a recombinant of the opposite type that is also produced.
Answer:
D. Pheasants that pecked immediately after hatching had the highest survival and reproductive success
Explanation:
This means that behavior of pecking increased their survival and reproductive success and become favorable by natural selection.
Natural selection is evolutionary mechanism which favours traits (structures, behavior) of an organism that help him survive and reproduce. In the example, above, pheasants that pecked survived and that was the favorable trait by natural selection.
The three major types of rocks are sedimentary, metamorphic, and igneous. Did this help?
