Liquefied salts in sea water make The ocean is salty because of the salt that dissolves in sea water. Seawater can become saturated with dissolved salts. Certain marine animals can remove these salts from sea water and produce protective shells or build a reef, when the water cannot hold anymore salt since water can only hold a certain amount of dissolved solids. During dry conditions, minerals are formed as the water evaporates then solids crystallize out of the water. On the other hand, atoms and ions arrange themselves and form mineral crystals when the magma-as an ash or lava ash cools above the ground or magma cools below the ground.

The minerals are formed on earth by the natural processes, such as from the process of evaporation, crystallization of magma and that are crystallized directly from sea water. The formation of minerals depends upon the type of minerals and elements that are present in that area. The temperature and pressure plays an important role in forming these minerals.

The water is mostly comprised of various types of dissolved substances. As the water gets evaporate, the minerals are precipitated. For example, Gypsum and Halite are formed by this process.

The hot sea water often flows through the interconnected pores, dissolving minerals under the earth's crust. This water when cools, the dissolved minerals gets separated from the water and again forms solid. For example, gold is formed by this process, which dissolves in the hot water that flows through the crust. As the water starts cooling, it again forms solid.

The minerals are also formed when magma above or under the earth's surface undergoes crystallization and solidification, resulting in the formation of extrusive and intrusive igneous rocks respectively. These minerals are combined with one another forming rocks. For example, granite, basalt, lava.

Imagine you are a student in alfred hershey and martha chase's lab in the late 1940's. you are given five test tubes with the e. coli bacteria that were infected with t2 bacteriophage that have been labeled with 32p or 35s. unfortunately, you forgot to label the tubes and are now uncertain which were 32p labeled and which were 35s labeled. you place the contents of each tube in a blender and pulse it for a few seconds to shear off the protein coats from the bacterial outer membranes. you then centrifuge the contents to seperate the protein coats and the bacterial cells. you then check for radioactivity and obtain the results shown below. which tubes contained e. coli infected with the phage labeled with 32p? select all tubes that apply.
