During development embryonic cells will fuse to form muscle fibers. this will result in a. interlocking of cells that can prevent the filaments from sliding b. the coordination of nerve signals to muscle fibers c. the striations that appear in skeletal and cardiac muscle tissues d. multinucleated muscle fibers that can extend as long as 30 centimeters

Look at the photo of the leaf. which term best describes this leaf?

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.

The “ecological footprint” left by a citizen of a developed nation is about four times larger than that left by a citizen of a developing nation. why is this the case?
