What triggers the sodium-potassium pump? The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell. […]
What is 0.78 rounded to the nearest tenth?
How many electrons must be gained by S to achieve a stable electron configuration?
How many electrons must be gained by S to achieve a stable electron configuration? 2 electrons Which of the following would have to gain two electrons in order to achieve a noble gas electron configuration? Explanation: Elements located in group VIA needs to gain 2 electrons to achieve noble gas electron configuration. Oxygen (O) is […]
What is an example of genus and species?
What is an example of genus and species? A genus consists of a large number of organisms, whereas species consists of a fewer number of organisms. The best example is animals like zebra, horses, and donkeys which belong to the same Genus “Equss”. Meaning all the different species of zebra, donkey, and horses all belong […]

What is an example of an estuary? Other examples of coastal plain estuaries include the Hudson River in New York, Narragansett Bay in Rhode Island, the […]
How can you determine the direction of field lines?
How can you determine the direction of field lines? A magnetic field line is the path along which a free north-pole tends to move. The direction of a magnetic field at a point is determined by placing a small compass needle. The N – pole of compass indicates the direction of magnetic field at that […]
How are humans destroying wetlands?
How are humans destroying wetlands? Common direct impacts to wetlands include filling, grading, removal of vegetation, building construction and changes in water levels and drainage patterns. Most disturbances that result in direct impacts to wetlands are controlled by State and Federal wetland regulatory programs. Why did we destroy wetland? Wetlands serve as a source of […]
Does an experiment need a control group?
Does an experiment need a control group? An experiment may include multiple experimental groups at one time. A control group is a group separated from the rest of the experiment such that the independent variable being tested cannot influence the results. While all experiments have an experimental group, not all experiments require a control group. […]
How do you measure a caliper diameter?
How do you find the refractive index of oil?
How do you find the refractive index of oil? The refractive index of essential oils can easily be measured with an Abbemat refractometer. It can thus provide insight as to their quality. Does oil have the same refractive index as glass? You see a glass object because it both reflects and refracts light. When light […]
