Potassium ions act as if they were nonpenetrating solutes in the intracellular fluid and as sodium, chloride, and ions in the extracellular fluid. they are pumped back out because
<h3>What is the Na+- K+ pump's principal function in preserving the resting membrane potential ?</h3><h3 />
The Na+ K+ -ATPase pump helps living things maintain their osmotic equilibrium and membrane potential. The sodium and potassium withstand concentration gradients. The Na+ K+ -ATPase pump maintains the gradient between a higher concentration of sodium extracellularly and a higher concentration of potassium intracellularly.
- A change in K+ conductance would have a greater effect on the resting membrane potential than a change in Na+ conductance because the membrane is more permeable to K+.
- If the extracellular potassium ion concentration decreased, more potassium would leave the cell, causing the electrical gradient across the membrane, or transmembrane potential, to increase. This state is known as hyperpolarization.

Answer:
Energy
Explanation:
all of life relies on the sun. all living things need energy that the sun provides or will be effected by not having the sun.
Answer: Sterilization refers to any process that eliminates, removes, kills, or deactivates all forms of life (in particular referring to microorganisms such as fungi, bacteria, viruses, spores, unicellular eukaryotic organisms such as Plasmodium, etc.) and other biological agents like prions present in a specific surface, object or fluid, for example food or biological culture media. Sterilization can be achieved through various means, including heat, chemicals, irradiation, high pressure, and filtration. Sterilization is distinct from disinfection, sanitization, and pasteurization, in that those methods reduce rather than eliminate all forms of life and biological agents present. After sterilization, an object is referred to as being sterile or aseptic.

Answer:
Condensation
Explanation:
Condensation is the process by which water vapor in the air is changed into liquid water.
Answer:
pH of 6.5
Explanation:
The pH favorable to an enzyme where it is most active is called optimum pH. The optimum pH of sucrase is about 6.0 while that of catalase is 7.0. Both enzymes can however still show some activity when the solution is slightly basic or slightly acidic (from it's optimum pH). Hence, getting the middle point (6+7/2 = 6.5) between the optimum pH of the two enzymes and preparing same will ensure the enzymes show some activity.
