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.
Answer:
Classification of biological organisms from most general to most specific is -
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
Explanation:
A hierarchy system of taxa or ranks of living organisms up to species level is known as taxonomic classification. It includes a higher and most generalized rank domain consist of archaea, bacteria, and eukarya. Second most generalized ranks kingdom that consist of various kingdoms.
Less generalized ranks are in order of a decrease in general and an increase in specificity are phylum, class, order, and family and the most specific ranks are genus and species.
Answer:
Chloroplasts are the food producers of the cell. They are only found in plant cells and some protists. Animal cells do not have chloroplasts. Every green plant you see is working to convert the energy of the sun into sugars. Plants are the basis of all life on Earth. They create sugars, and the byproduct of that process is the oxygen that we breathe. That process happens in the chloroplast. Mitochondria work in the opposite direction and break down the sugars and nutrients that the cell receives.
