Put the following events in the order they occur, resulting in depolarization of the olfactory receptor neuron membrane. 1. Adenylyl cyclase converts ATP into cyclic AMP 2. Cl- efflux depolarizes the olfactory receptor neuron 3. Odorant binds to receptor 4. Receptor binds to Golf which dissociates into Galphaolf and beta-gamma subunits 5. cAMP binds and activates cyclic nucleotide-gated Na and Ca2 cation channel 6. Galphaolf binds to and activates adenylyl cyclase 7. Ca2 activates a Ca2 gated Cl- channel A. 4,3,1,5,6,7,2 B. 3,4,6,1,5,7,2 C. 4,7,2,5,6,1,3 D. 3,5,6,4,1,7,2

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
