Explanation:
To prevent the invasive species from entering texas freshwater ecosystem the following steps should be taken they are described below.
Explanation:
The invasive species are dangerous to natural resources because they destroy the natural resources and ecological system.
These invasive species are controlled by the biological control and mechanical control.
Thus to prevent the invasive species from entering texas freshwater ecosystem the following steps are taken they are
- Always clean and dry any equipment used in or around lakes or rivers after each use.
- Spray off your boat after you take it out of the water.
- Never dump aquarium or pet species into sewer system of waterways.
A picture is needed to answer.
Gram's staining is a differential staining technique that employs a primary stain like crystal violet and a counter stain like safranin along with the decolourizing agent alcohol and a mordant called the Gram's iodine.
Iodine is a mordant added after the primary stain. It fixes the stain by combining with it to enchance the staining ability. This forms an insoluble crystal violet iodine complex appearing purple under the microscope. These microorganisms are classified as Gram positive.
If addition of iodine is skipped, crystal violet is not fixed on the slide and the insoluble complex is not formed. The cells are decolourized by alcohol and are stained by the counter stain safranin making the Gram positive cells wrongly indentified as Gram negative due to its pink colouration. Thus, the slide will show all the cells as pink coloured Gram negative cells.
