This tiny cluster of bacteria is methicillin-resistant Staphylococcus aureus (MRSA), seen under a microscope. This strain of the common staph bacteria causes infections in different parts of the body -- including the skin, lungs, and other areas. MRSA is sometimes called a superbug because it doesnât respond to many antibiotics. Though most MRSA infections are minor, some can be life-threatening.
Granite is an igneous rock that injects, or intrudes, as magma into Earth's crust and then cools. It consists of four main mineral compounds. Two of these are types of feldspar, a group of silica compounds that constitute the most abundant mineral group on Earth.ranite is an igneous rock that injects, or intrudes, as magma into Earth's crust and then cools.

Granite and Basalt:   1. Granite is formed from magma that cooled slowly, so it has a coarse-grained texture. It may be pink, white-gray or light to moderate yellow. It con â¦ tains the minerals feldspar, quartz and mica.ranite is hard to scratch with a fingernail.   2. Basalt is formed from lava that cooled rapidly, so it has a fine-grained texture. Its mineral grains are so tiny that they can be seen only through a microscope. It may be black or dark green. It contains the minerals feldspar and olivine.
