The oxygen level of a lake suddenly starts decreasing. a biologist believes that photosynthetic organisms in the community have become less efficient at producing oxygen. a geologist believes that changes in the ground have increased the inflow of water into the lake. why are both of these options valid scientific hypotheses?
scientists with different educational backgrounds can come to different interpretations of the same data.
both scientists have graphs and charts to support their hypothesis.
both are valid because they are supported by experimental data
both scientists underwent the same training and, therefore, have equally valid scientific hypotheses regardless of the available data.

Scientists with different educational backgrounds can come to different interpretations of the same data.

Choice A is correct

Explanation:

A biologist is a scientist with specialized knowledge in the field of biology while a geologist is a scientist who studies the matter that make up the Earth as well as the processes that shape them.

Both scientists came to different interpretations of the same data since they have different educational backgrounds.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
