Imagine your teacher asks you to design an experiment where you test the effect of temperature on the growth of a plant. You have 5 plants that you plant and place in different temperatures around the room. What would your variables be (independent and dependent) and what would your constants be(controlled variables) ? What would you do for a control

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 × 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.

Could someone me find the answer to this problem.

Most of the volume of an atom is occupied by the
