A. Suzie Q wants to know the effect of different colors of light on the growth of plants. She believes that plants can survive b

est in white light. She buys 5 ferns of the same species, which are all approximately the same age and height. She places one in white light, one in blue light, one in green light, one in red light and one in the closet. All of the ferns are planted in Miracle-Grow and given 20 mL of water once a day for 2 weeks. After the two weeks, Suzie observes the plants and makes measurements.

Answer:

This question is incomplete, the complete part is: What is the independent variable in this experiment? A) The plant species B) The amount of water that each plant gets C) The amount of time D) The different types of light the plants were put under.

The answer is D

Explanation:

In an experiment, the INDEPENDENT VARIABLE is the variable that is changed or manipulated by the experimenter in order to effect a measurable response.

In this case, Suzie Q wants to know the effect of different colors of light on the growth of plants. She conducts this experiment using different colors of light namely: white light, green light, blue light, red light etc. This shows that the variable being changed/manipulated is the different colors of light. Hence, the INDEPENDENT VARIABLE is the DIFFERENT TYPES OF LIGHT THE PLANT WERE PUT UNDER.

in order to keep a resting membrane potential, the active transport of the sodium and potassium pump must function to keep:
krek1111 [17]

The active transport of the sodium and potassium pump must work to maintain: A high concentration of sodium outside the cell and a high concentration of potassium inside the cytosol in order to maintain a resting membrane potential.

Active transport in cellular biology refers to the movement of molecules or ions across a cell membrane against the concentration gradient from a location of lower concentration to a region of higher concentration. Cellular energy is needed for active transport to achieve this movement.

The electrical potential differential across the plasma membrane of a cell during its non-excited condition is referred to as the resting membrane potential of the cell. The value of the electrical potential difference inside a cell compared to the extracellular environment is often used to indicate the difference across a cell membrane.
