Arrange the following sentences to describe the sequence of events that can occur during skeletal muscle contraction 1.Sodium channels open and sodium flows in. 2.Impulse reaches the axon's terminal. 3.ACh binds to receptors on the muscle cell membrane. 4.Synaptic vesicles fuse with neuron's membrane and release ACh via exocytosis. 5.If enough sodium moves in to the muscle cell, an impulse (action potential) develops.

are these strong bases, neutral, strong acids, weak acids or weak base household bleach (ph=12.6) fluid in a car's battery (ph of less than 1.0) milk (ph=6.7) stomach contents (ph=2.2) pure water (ph=7)

household bleach (ph=12.6)= strong base

fluid in a car's battery (ph of less than 1.0) = strong acid

milk (ph=6.7)=neutral

stomach contents (ph=2.2)=strong acid

pure water (ph=7) =neutal

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."

not necessarily. higher fitness requires the organism to be reproductive successful. for example, an organism at age 10 with 15 offspring is much more fit than an organism at age 15 with only 5 offspring.
