Answer:
Extrusive igneous rock is formed by the crystallization of magma release after volcanic eruption at the Earth surface. They are characterized by fine grained textures because of rapid cooling they do not form large crystals. Extrusive rocks with fine grained textures are called aphanitic rocks. The most common extrusive igneous rock is basalt. Other examples include rhyolite, andesite and obsidian. Extrusive igneous rocks erupt quickly and they form small crystals. Some of these rocks cools slowly that they form glass. These rocks includes andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria and tuff.
The common characteristic of extrusive igneous rock is the b. forms crystals
Rapid cooling of magma produces small crystal rocks.

Explanation:
During the lytic cycle, bacteria takes over the cell, reproduces new phages, and destroys the cell. It works in 5 phases
1. The virus or phage attaches itself to the cell
2. The phage enters the cell
3. Biosynthesis- Phage DNA replicates and makes phage proteins
4. New phage cells assemble
5. The cell lyses emerge with a new plague
