<span>These are viroids. They are some of the smallest types of matter that have been shown to take on the properties of living beings. They have the ability to replicate, while not having many of the mechanisms that are commonly found in DNA and required for them to replicate.</span>
33% is the unknown concentration of the tube.
Explanation:
Concentration of stock of windex = 50%
concentration of bacteria = 500 microliter
nutrient broth = 1000 micro litre +500 microlitre of windex
concentration of bacteria is the volume of bacteria present in nutrient broth culture.
total volume in the tube is 1000
50% is the concentration of tube of bacteria and broth before adding windex.
After adding windex of 50 % concentration and the volume is 500 microliter which is only 250 microliter of windex rest is water.
33% is the concentration of the tube, which means it has 33% of bacteria in 1500 ml of solution.
10
Explanation:
The Ritcher scale is a logarithmic scale and it suggests that the number increases by a factor of 10.
One point on the scale differs from another by an order of 10.
- The Ritcher scale is used to measure the magnitude of earthquakes in a particular area.
- It is graduated form 1 to 10
- The magnitude of the quake increases as one moves from 1 through 10.
- This is because the magnitude of the quake actually increases by an order of 10.
