Hi. You have not submitted any images about the microorganism the question refers to. This makes it impossible for me to answer your question. However, I will try to help you as best I can.
Gram stain is a test done to find out whether the bacteria are gram negative or gram positive. In this test, the bacteria are submitted to a certain type of dye and then are observed under a microscope. If the bacteria is gram positive, it will be purple in color. If the bacteria is gram negative, it will be red in color.
This is because after they are subjected to the violet dye, both types of bacteria absorb the color of the dye. However, before being observed under the microscope, the bacteria are washed with alcohol. Alcohol removes the dye from the gram negative bacteria, leaving them reddish. On the other hand, in gram positive bacteria, alcohol dehydrates the cell wall, compressing the pores and making the cell wall impermeable, preventing the dye from being released and, therefore, leaving the bacteria with a purple color.
The answer is B) cleavage. I just took the test. And also I had it in my notes. Hope this helps :)
Humans live in the layer of the atmosphere referred to as the troposphere. (Most of the mass of the atmosphere can be found in the troposphere.)
A. is the correct answer. Qualitative observation deals with data that can be observed with our senses.
The neurons of area V4 are
important for the analysis of color. The area characterized as the color
area is Area v4. This is said to be the where the color is further processed.
Because of the strength of the color receptive field in its neurons, this is
the reason why v4 is an area of interest. Initially, Zeki introduced v4 to be solely
involved in processing of color but then this was proved to be incorrect.
Later, it was found out that v4 is responsible for processing both color and at
the same time form associated with color. In the extended v4 occur in color modules
called globs.
