-Viruses are 10 to 100 times smaller than bacteria-Viruses need a living host; bacteria can grow on non-living surfaces-Antibiotics don't work on viruses, because antibiotics interfere with cellular processes that viruses do not perform.Differences Between Bacteria and Viruses are: î î î.Are small DNA fragments-Each fragment carries between 2 and 30 genes-Some plasmids have the ability to move in and out of the bacterial chromosome-Plasmids are not needed for the cell's growth or reproduction, but can cause disease or can protect the bacterium from things like antibiotics.
Check out this page for a simple soil content test. The soil's pH rating is also important. This rating tells you the relative acidity and alkalinity of the soil (this page explains the concept). The ideal pH level is around 6.5 or 7, but levels vary between different grass species and climate conditions. You can find out your soil's pH level with a home test or a professional test. If you need to substantially increase the acid level, add sulfur.
A pH determination (soil test) will tell whether your soil will produce good plant growth or whether it will need to be treated to adjust the pH level. For most plants, the optimum pH range is from 5.5 to 7.0, but some plants will grow in more acid soil or may require a more alkaline level.The pH is not an indication of fertility, but it does affect the availability of fertilizer nutrients. pH determination (soil test) will tell whether your soil will produce good plant growth or whether it will need to be treated to adjust the pH level.
