You have immersed a skeletal muscle fiber and its attached motor neuron ending in a lipid-soluble compound that fluoresces in the presence of high concentrations of ca2+ ions. what region in this set of structures will fluoresce when the muscle and nerve are both unstimulated?

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

explanation:

a

the population of unionid mussels in the hudson river decreased after zebra mussels were introduced. zebra mussels, a nonnative species, competed with the unionid mussels for food. the zebra mussels were able to outcompete the unionid mussels, allowing the zebra mussel population to increase dramatically over six years. the unionid mussel population decreased due to a lack of food.
