Only the non-covalent bonds like hydrogen bonds which give it's functional shape.
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.
Spring tides have the largest difference between low and high tides. They only occur during Full and new moons or when the Sun , Moon, and Earth are in a straight line. Neap tides have the smallest difference between high and low tides and only occur during a 1st or 3rd quarter moon or when the Sun, Moon, and Earth are at a 90 degree angle.
