Habitat destruction is the leading cause for declining populations of species on our planet. due to human development, industry, and forestry, humans are destroying the habitat of many species at an alarming rate. consider the bald eagle. the bald eagle population was threatened in the late 60s and early 70s. to an aggressive bald eagle protection program, bald eagle numbers in the wild have soared as seen in the population graph above. the bald eagle's population very nearly reached extinction. why did the bald eagle's declining population make it more vulnerable to extinction?

How can a geological time scale best be reconstructed? a) comparing vestigial structures in living species b) comparing homologous structures in living species c) examining homologous structures in fossil remains d) examining the written records of scientists from past cultures

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails. b. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. c. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions,because prokaryotes don't have nuclei.

At which point is crust neither created nor destroyed? island chain mid-ocean ridge divergent boundary transform boundary
