The neuron maintains a resting membrane potential. ... Because potassium is in high concentration inside the neuron, there is a concentration gradient attempting to force potassium out of the cell. Similar forces will attempt to move sodium ions into the neuron. so the answer is A ions
Main Answer:
Given data:
Initial Pressure P1 = 570 mm hg
Initial Volume V1 = 2270 ml
Final Pressure P2 = ? mm hg
Final Volume V1 = 1250 ml
According to the ideal gas equation,
PV = constant.
P1V1 = P2V2
P2 = P1V1/V2
P2 = (570 x 2270) / 1250
P2 = 1035.12 mm hg
The final pressure at volume of 1250 ml is 1035.12 mm hg.
Explanation:
What is ideal gas equation ?
The ideal gas equation is as follows:
PV = nRT
where P = Pressure
V = Volume
n = number of moles of gas
R = Universal gas constant
T = Temperature
This ideal gas equation provides the macroscopic particles behavior of the gas. At this condition, the particles of the gas, won't be attract or repel each other. It is consider as the stable condition.

Answer: How do contrasting colors affect the quality of a painting?
Explanation:
The object study of science is objective phenomena, which are those phenomena that can be measured in a form that every ones agree because they do not depend on the particular subject that is involved in the study.
Color of light, mating behaviors of bees, soil pH, the productivity of fruit trees, temperature, and the amount of oxygen able to dissolve in water are variables or characteristics that can be objectively measured, so they can be perfectly object of study of and answered by science.
On the other hand, the ability to contrast color and the quality of paintings are characteristic that are subjective: they depend on the subject that assess such properties. This makes that a question like "How do contrasting colors affect the quality of a painting?" cannot be answered by science.
Answer:
B. plants use the energy from sunlight to produce food.
