The Carbo Foods company produced 2000 cupcakes in its first day of operation. We would like to know the average amount of sugar in these cupcakes. Scientists randomly select 50 of the company’s cupcakes produced on that first day. The scientists find that the 50 cupcakes have an average of 30 grams of sugar each. • a) What is the population of interest in this experiment? • b) What is the population size, N ? • c) What is the sample in this experiment? • d) What is the sample size, n ? • e) Describe the sample results. • f) Based on the sample results, what might we infer about the population?

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.

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
