Answer:
1. Potassium
2. increasing towards zero
3. hyperpolarization
4. voltage-regulated Potassium
Explanation:
Membrane potential can be defined as the difference in electric charges inside and outside of a cell. The resting membrane potential (RMP) occurs when there is no net current across the membrane and therefore the cell is in a non-excited state. At the RMP, sodium ions (Na+) are more concentrated inside the extracellular fluid (ECF) than inside the intracellular fluid (ICF), while potassium ions (K+) are more concentrated inside the ICF. The diffusion of K+ outside the cell triggers its hyperpolarization, by becoming the membrane potential more negative compared to the resting potential. As the potential nears +35 mV, the voltage-regulated potassium channels are open, thereby K+ ions leave the cell down its concentration gradient, while voltage-gated Na+ channels become saturated and inactivate.
Answer:
I believe the correct order of the eukaryotic gene expression, from beginning to end would be: (4), (1), (3), and then (2).
Explanation:
This is because in order to make RNA, you must have a "template," or DNA. (4) The DNA is then copied. (1) the mRNA is then transported out of the nucleus and into the cytoplasm where it is connected to ribosomes. (3) The mRNA is now in the ribosomes, so the ribosomes translate the mRNA and all the thymine bases would be replaced with uracil to make proteins. (2)

Answer:
What Keene High school students are you reading about? And what scientist are you talking about? If you had given more information I would have helped. Anyways, just look at what it says in the book that the scientist did, and what the Keene high school students did. And see what they both have in common.
