Density=mass/volume so solving for mass you get mass=density*volume=10ml*3.5g=35g
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.

Explanation:
Mechanical weathering is the physical disintegration of rock into bits and masses.
In this process, agents of weathering combines to fracture rocks into bits. There are different type of mechanical weathering. It is also known as physical weathering.
- Frost wedging occurs in temperate and polar regions where temperature is very low. Cracks in rocks are filled water and when the freezes it expands. As the water melts during summer and freezes in the winter, frost wedge forms.
- Salt crystal growth on rocks can cause mechanical weathering.
- Pressure release from the surface of rock leads to exfoliation domes.
- Wetting and drying of a rock leads to mechanical weathering
- Expansion and contraction of rock
