You can tell them apart from its form.
If it forms loose and needs like a container to hold it up, that's liquid.
If it is hard and stable, definitely a solid.
And if you barely see something very loose (and normally goes up), that's liquid.
Answer:
Drip rate = 2 ml/h
Explanation:
Given:
Amount of insulin = 500 unit
Amount of saline = 250 ml
Required infusion rate = 4.0 units/h
Find:
Drip rate
Computation:
Concentration = Units of insulin / Volume of saline
= 500 / 250
Concentration = 2 units/ml
Drip rate = Infusion rate / concentration
Drip rate = 4 / 2
Drip rate = 2 ml/h
Answer:
Heat transfer in the atmosphere from the equatorial regions to higher latitudes occurs through the process of Convection
Explanation:
The equatorial regions of the earth's surface receive the most heat from the sun than any other region of the earth. This is because the are most directly in line with the direct heat from the sun.
Due to this heat from the sun, atmospheric air around the equatorial regions are hot and less dense than air in regions of higher latitudes, and thus, rises above the equator. The rising air at the equator is replaced by colder and denser air from higher latitudes north and south of the equator. As the rising air of the equatorial regions are being replaced by colder and denser air from higher latitudes, the hot and humid air moves away from the equator, toward regions of higher latitude, north and south thereby setting up a convection current of heat flow.
Each mole of nitrogen that microbes fix requires the breakdown of 16 moles of ATP (adenosine triphosphate). The energy needed by these microbes is obtained by oxidizing organic compounds. In other words, the nitrogenase enzyme must use a significant amount of energy to convert N2 to NH3.
The great majority of nitrogen on Earth exists as molecular N2, and before to the agricultural and industrial revolutions, the only significant mechanism producing reactive nitrogen was biological nitrogen fixation. Any natural or artificial process known as nitrogen fixation causes free nitrogen (N2), a relatively inert gas present in large quantities in the atmosphere, to chemically interact with other elements to generate more reactive nitrogen compounds like ammonia, nitrates, or nitrites. carbon cycle.
