A biologist began studying a population of buildings. In 1998, she found that most of the male frogs croaked, but some did not. A bat species known to prey on male frogs migrated to the area in 2005. The biologist returned to the area in 2008 and repeated population counts of male frogs. The table shows her data. Based on the data, which statement is a plausible explanation for the change in the frog population between 2004 and 2008?

Can someone me with this and tell me what’s fracking and what does it have to do with carbon, carbon dioxide, or fossil fuels?

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.
