Answer:
D. her skeleton was 40% intact and undisturbed
Explanation:
Lucy was one of the most important discoveries in human evolution. Before the finding of Lucy majorities of the human ancestor bones were not much more than only some bone fragments.
Lucy was the first most complete Australopithecus which was ever found. Lucy was approximately 40% complete fossil. It was found that her brain size was smaller than today's man but she was bipedalism. She was a new species of Australopithecus- Australopithecus afarensis. So the right answer is D.
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.

its actually really healthy and is quite easy once u get the hang of it. u end up eating more veggies then u might want but it really healthy and benfits you more than the meat does. ive been a vegetarian forever (never eaten meat before ever) and im athletic and everything just like any other meat eater
