During signal transduction A. a signaling molecule directly activates or represses some genes. B. enzymes in the signal cascade remain active until the last component of the pathway alters a cellular process C. the signal is terminated by cAMP D. each enzyme catalyzes production of one molecule of product E. the cell converts an extracellular signal into an intracellular signal that leads to a change in some cell process

Which of the following is a difference between active transport and facilitated diffusion? view available hint(s)which of the following is a difference between active transport and facilitated diffusion? facilitated diffusion can move solutes against a concentration gradient, and active transport cannot.active transport involves transport proteins, and facilitated diffusion does not.facilitated diffusion involves transport proteins, and active transport does not.active transport requires the expenditure of cellular energy, and facilitated diffusion does not.

What will a hypothesis become if supported by repeated expermentation

The biological classification of organisms is called taxonomy. based on your own investigation, discuss the importance of taxonomy in biological ?
