Answer:

Active transport by the Na+-K+ pump

Explanation:

Active transport by the Na+-K+ pump

Maintenance (and restoration) of the resting ion concentrations depends on the Na+-K+ pump. Once gated ion channels are closed, the combined action of the pump and ion leakage (particularly that of K+) establishes a resting membrane potential in a typical neuron of around âˆ'70 mV.

Analytical chemistry studies and uses instruments and methods used to separate, identify, and quantify matter. In practice, separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes
Chemical engineers use chemistry and engineering to turn raw materials into usable products, such as medicine, petrochemicals, and plastics on a large-scale, industrial setting. They are also involved in waste management and research. ... They may be involved in designing and constructing plants as a project engineer.
A healthcare scientist or medical scientist is a scientist working in any of a number of health related disciplines. Healthcare scientists may work directly for health service providers, or in academia or industry.
Forensic science, also known as criminalistics, is the application of science to criminal and civil laws, mainly—on the criminal side—during criminal investigation, as governed by the legal standards of admissible evidence and criminal procedure.
Research scientists are responsible for designing, undertaking and analysing information from controlled laboratory-based investigations, experiments and trials. You could work for government laboratories, environmental organisations, specialist research organisations or universities.
Toxicology is a scientific discipline, overlapping with biology, chemistry, pharmacology, and medicine, that involves the study of the adverse effects of chemical substances on living organisms and the practice of diagnosing and treating exposures to toxins and toxicants.
A medicinal or pharmaceutical chemist researches and creates chemical compounds for use as drugs. By applying chemical research techniques to isolate natural healing agents or develop artificial ones, these chemists play a vital role in the pharmaceutical industry.
Nuclear chemists conduct basic, applied, or theoretical research. They often work in laboratories and may be responsible for operating, maintaining, and repairing state-of-the-art instrumentation.
Some industrial chemists work to improve product efficiency or to create better building materials, plastics, textiles, or petroleum products. They may help to set new industry standards, improve production techniques, and increase the effectiveness of various chemical processes.

Explain the difference between passive transport and active transport

garri49 [273]

Energy is not required in passive transport, and in active transport energy is required.
In active transport, the molecules move against the concentration gradient that is from low to high concentration.
In passive transport, the molecules move with the concentration gradient thatis from high to low concentration.

Calculate the percent ionization of 0.110 m lactic acid (ka=1.4×10−4).

Volgvan

You need to have in mind the following equations given two different notations:
In Organic notation you write the lacti acid calculation like this: 
CH3CH(OH)COOH(aq) <----> CH3CH(OH)COOH-(aq) + H+ (aq) 
Now the simplified formula equation will be: 
HC3H5O3(aq) <-----> H+(aq) + C3H5O3(aq) 
0.110 - x M .................. x M ............. x M 
havign the regular formula you proceed as follows:
Ka = [H+] [C3H5O3] / [HC3H5O3] 
1.4x10^-4 = (x)(x) / (0.110 - x)
Do the maths and you will get the answer.
