The answer is : A bios or cmos jumper. The jumper acts as a switch by closing (or opening) an electrical circuit. Clearing the CMOS on your motherboard will reset your BIOS settings to their factory defaults. After clearing the CMOS, you'll need to access the BIOS setup utility and reconfigure your hardware settings.

Answer:
Humans gain more energy from eating the plants rather than the cow.
Explanation:
More consumers in a chain of eating means less energy reaches the final consumer. Approximately 10% of the energy from food is given to the consumer when eaten, and this chain continues down the line of consumers. This is known as the 10% rule in biology. This rule is used by an ecosystem to limit the amount of animals it can support.
Answer:
E. All of the above
Explanation:
In cardiac contractile cells there is rapid depolarization, then a plateau phase and repolarization.
when an action potential stimulates the cell, voltage-gated channels open quickly commencing the positive-feedback mechanism of depolarization. This in turn raises the membrane potential to approximately +30 mV, and this closes the sodium channels. Next comes the plateau phase, where membrane potential declines relatively slowly due to the opening of the slow Ca2+ channels, allowing Ca2+ to enter the cell while few K+ channels are open, leading to K+ to exit. Once the membrane potential reaches approximately zero, the Ca2+ channels close and K+ channels open, allowing the exit of K+. The repolarization lasts approximately for a while and here is when the membrane potential drops until it reaches resting levels once more and repeats the cycle.
I think it is the second one I'm in bio right now and we just finished the energetics unit.
