PLEASE PLEASE PLEAS HURRY I NEED THIS IN LIKE 20 MINS FOR I FAIL( I'm saving up for a give away so not that many points) You observed light passing through lenses and through a set of prisms. Why does refraction occur? Include your lab observations in your answer.

Light bending

Explanation: light slows down when passing through the glass. Each color slows down a different amount making light bend

Since it wasn't enough info here, When light passes through lenses and through a set of prism then refraction will take place as the light is traveling from a rarer medium (air) to the denser medium (prism or lens). It is because of the change in the speed of the light.

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.

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).
