d) Cells can divide up the labor of performing essential physiological processes. correct answers Which of the following is a main benefit of multicellularity? a) Each cell can perform all of the necessary physiological processes needed by the body. b) Each cell can dump its waste directly into the environment c) Only some body cells need to make ATP. d) Cells can divide up the labor of performing essential physiological processes. e) Each cell has direct access to nutrients in the enviro...

Basics of diffusion, gradients, and how they relate - Diffusion: spontaneous movement of very small things. It requires no energy investment by the organism (other than keeping the temperature above freezing) --direction is random Gradients: top of gradient = high concentration, bottom of gradient = low concentration --diffuses high to low Basics of diffusion across a semipermeable barrier - Factors that speed up or slow down diffusion - size: smaller things diffuse faster the visco...

Macroevolution changes in a population over very long periods of time. Speciation the splitting of one species into two or more new species Biological Species Concept offers testable way to define a species that does not depend on appearance: The members of a species interbreed and have a shared gene pool, & each species is reproductively isolated from every other species. Gene flow occurs between the populations of a species, but not between pops of diff species. Biolo...
