Is viruses larger than bacteria and human cells?
Viruses are generally smaller than bacteria and human cells. Viruses are usually measured in nanometers (nm), bacteria are typically larger, ranging from about 1 to 10 micrometers (µm), and human cells are even larger, ranging from about 10 to 100 micrometers.
What is the minimum CO2 level required for optimal plant growth?
The minimum CO2 level required for optimal plant growth is around 150 parts per million (ppm).
What is the optimum CO2 level for plant growth?
The optimum CO2 level for plant growth is around 400 parts per million (ppm). This concentration allows plants to efficiently photosynthesize and grow.
Why is the medial condyle larger than the lateral condyle?
The medial condyle is larger than the lateral condyle in order to help stabilize the knee joint. This asymmetry helps with weight distribution and allows for better support and movement of the knee. Additionally, the medial condyle tends to bear more weight during activities, so it needs to be larger for increased strength and stability.
What is a bird that looks like a pigeon but is larger in size called?
A bird that looks like a pigeon but is larger in size is called a dove.
What is 28 ppb equal to in ppm?
To convert parts per billion (ppb) to parts per million (ppm), you divide by 1000. So, 28 ppb is equal to 0.028 ppm.
How do you convert parts per billion to parts per million?
1000 ppm = 1 ppb I think equation to convert ppm to ppb is: 1 ppm = 1000 ppb, or 1 ppb = 1/1000 ppm * * * * * Wrong way around, I am afraid. 1000 parts per billion is 1 ppm. To convert ppb to ppm divide by 1000.
What is the composition of the atmosphere on Mars?
95.32% carbon dioxide2.7% nitrogen1.6% argon0.13% oxygen0.08% carbon monoxide210 ppm water vapor100 ppm nitric oxide2.5 ppm Neon850 ppb HDO300 ppb Krypton130 ppb formaldehyde80 ppb xenon30 ppb ozone10 ppb methaneNote: ppm stands for parts per million while ppb stands for parts per billion. 210 ppm of water vapour means water vapour makes up 210/1,000,000 of the atmosphere.
What do the acronyms ppb and ppm represent?
PPB stands for parts per billion and is used to measure the concentration of a substance in a mixture. PPM stands for parts per million, and is another unit of measurement like ppb, but represents a higher concentration in a mixture.
How much does 15ppb weigh?
ppb is not a weight, but a ratio. "parts per billion"
What are the differences between ppm and ppb?
PPM-Parts Per Million: Number of grams of solute per 1 million grams of solution. ppm=[mass of solute/mass of solution]*10 to the 6th power&PPB-Parts Per Billion: Number of grams of solute per 1 billion grams of solution.ppb=[mass of solute/mass of solution]*10 to the 9th power.Hope this helps.
How can you prepare 1ppb from1000ppm sodium standard?
To prepare a 1 ppb sodium solution from a 1000 ppm sodium standard, you can dilute 1 mL of the 1000 ppm sodium standard with 999 mL (or 999 g) of solvent. This will result in a final solution with a concentration of 1 ppb, as 1 mL is equivalent to 1 mg in this case.
How many parts per million is 58 parts per billion?
58 ppb = .058 ppm
What does PPM in water means?
These are units that indicate a very small amount of the substance being measured. Generally air or water contaminates are measured in ppm or ppb. ppm = parts per million ppb = parts per billion Concentration of carbon monoxide in underground carparks could be measured in ppm. Amount of contaminate in air could be ppm or ppb. Amount of cyanide gas? Amount of nutrient in soil or water? Amount of ozone in water purifying treatment facilities...
How common is uranium in the earths crust?
Crustal rocks: 2-3 ppm Sea water: cca. 3,3 ppb
Is micrograms per ml equivalent to ppm?
No. 1 ppb = 1 ug/L or 1 microgram per liter. You can find conversion charts on the web (http://waterontheweb.org/resources/conversiontables.html) Yes, ng/mL is equivalent to parts per billion. While it is true that 1 ppb = 1 ug/L, it is equally true that 1 ng/mL = 1 ppb. They are the same sice 1 ng is 1/1000 of a ug and 1 mL is 1/1000 of a L. All that has changed is the units, but they remain equivalent.
What is ppm-ppb-ppt used to express?
ppm = parts per million, eg. 1ppm = 1 part out of 1 000 000 = 1/1*106ppb = parts per billion, eg. 1ppb = 1 part out of 1 000 000 000 = 1/1*109ppt = parts per trillion, eg. 1ppt = 1 part out of 1 000 000 000 000 = 1/1*1012
