A refractometer is often used to test the specific gravity of a cell.
The mass of a cell phone would best be measured in grams (g) or kilograms (kg). These units are commonly used for measuring relatively small objects like cell phones.
The performance of a fuel cell is typically measured using metrics such as power output, efficiency, and durability. Power output is a measure of the electrical energy generated by the fuel cell, efficiency is a measure of how effectively it converts fuel into electricity, and durability measures how long the fuel cell can operate reliably. These metrics help evaluate the overall performance and effectiveness of the fuel cell technology.
Translation is the process where mRNA is decoded by ribosomes to produce a specific protein. It occurs in the cytoplasm of the cell after transcription has taken place in the nucleus of the cell.
A cell can be compared to a car in that both have specific components that work together to perform functions. For example, the mitochondria in a cell can be likened to the engine of a car, providing energy. The cell membrane is like the car's exterior, controlling what goes in and out of the cell, similar to how a car door allows entry and exit.

A refractometer is often used to test the specific gravity of a cell.
There are two measures, cell voltage and specific gravity of the electrolyte. Cell voltage is the simplest to measure. For most automotive, flooded cell (having liquid electrolyte) batteries, 12.6 volts is considered full charge, although it is typical to have 13 volts or a bit over. The specific gravity of a fully charged battery, measured with a hydrometer, is 1.265.

'Lead-acid' batteries, sometimes called 'wet' batteries, have lead plates and liquid sulfuric acid inside. As a cell charges up, the specific gravity of the acid increases, and as it discharges, the specific gravity of the acid decreases. So, measuring the specific gravity of the liquid in the cell is a quick and easy way to tell how fully charged the cell is. Anybody who owns and uses some 'wet' batteries also owns a hydrometer ... a gadget that measures the specific gravity (or density) of liquids. The most familiar type looks like a turkey baster, with a little glass glob inside that looks like a miniature thermometer and has numbers marked on it. To use this hydrometer, you squeeze the rubber bulb on top, stick the snout into a liquid, release the rubber bulb which draws some of the liquid up inside, and the little mini-thermometer inside floats in the liquid ... part of it above the surface and part of it below. The higher the specific gravity of the liquid is, the higher this little thing floats. So you look in on it, and read the number marked on it right at the surface of the liquid, and that's the specific gravity. If you're doing this, then you know what number you want to see, and you know whether the number you see means charged, discharged, or something in between. As I recall back in the day, I used to see specific gravity somewhere around 1.20 - 1.25 in each cell of a 48-v battery that was properly floated and equalized on its rectifier. But to be honest, that was a while ago. The constants of nature that define the elementary charge and the Atomic Mass Unit could well have changed since then.
A battery hydrometer which measures the specific gravity (relative density) of liquids, to determine the concentration of sulfuric acid in each cell.

Hydrochloric acid is used to inhibit cell division during a mitosis experiment. By treating cells with hydrochloric acid, researchers can pause the process of cell division at a specific stage, allowing for detailed observation and analysis of the mitotic process.
No.AnswerPresumably, you mean 'specific gravity' or, as it is known these days, 'relative density'? If so, the relative density of a lead-acid cell or battery is, indeed, a guide to that battery's state of charge -that's why we use a hydrometer to check the condition of a lead-acid battery. However, it would be wrong to say that the relative density of a lead-acid battery 'effects' the voltage -it merely is a guide to the state of charge. (Actually, it's the state of a battery's charge that affects its relative density.)
Cells are typically measured in micrometers
