Mutations can occur at higher rates in viruses.

Explanation:

The mutation rate of an organism refers to the rate or average number of errors which are formed in the genome of the organism’s progeny per base per replication cycle.

Accordingly the Mutations of viruses are the highest per base pair per generation mutation. Viruses can mutate more than a million times than the host’s body due to their virulence factor, evolution ability, and presence of a variety of traits.  

Of the DNA and RNA viruses, the RNA viruses like the Retroviruses having a much higher rate, for example, the HIV virus which is a Retrovirus has high mutation rate.

Naturally occurring solid mixture of one or more minerals and organic matter
alina1380 [7]

The naturally occurring solid mixture of one or more minerals and organic matter is known as a Rock.

A rock is a naturally occurring substances that is a solid mixture of one or more minerals together with organic matter.

<h2>Further Explanation;</h2>
  • Rocks are classified based on the chemical composition, texture and the way they are formed.  One type of rock may change from one form to another through a rock cycle.
  • Rock cycle is the process through each various rocks change from one form to another, normally an interchange between the three major types of rocks.

There are three major classification of rocks:

<h3>Sedimentary rocks </h3>
  • Sedimentary rocks are types of rocks that are formed through accumulation of sediments at low temperatures in tectonic layers and sinks. These sediments includes; pebbles, shells, sand and other material fragments.  
  • The sediments accumulates in layers and then harden into rocks over a period of time.
  • Examples of sedimentary rocks include; limestone and conglomerate
<h3>Metamorphic rocks</h3>
  • These are types of rocks that are formed as a result of changes that occurs due to intense heat and pressure under the surface of the earth. They result from action of heat and pressure on other rocks that pre-existed.
  • These types of rocks are characterized by shiny crystals, ribbon-like layers among other features.
  • Examples of metamorphic rocks are marble and gneiss

<h3>Igneous rocks </h3>
  • These are types of rocks that are formed as a result hardening and cooling of magma from volcanic eruptions. Magma may cool inside the earth or when on the surface of the earth as a result of volcanic eruptions. The lava from this eruptions cools and hardens to form metamorphic rocks.
  • Igneous rocks are glass-like and shiny with no crystals. They may also have tiny spaces and holes due to gas bubbles trapped during the cooling process.
  • Examples of igneous rocks include obsidian and basalt.
  • The three types of rocks may be further classified in terms of chemical composition, texture and formation.

Key words: Rocks, types of rocks, chemical composition

How igneous and sedimentary rocks turn to metamorphic rocks?
Darina [25.2K]

Answer:

Heat, pressure and chemistry compounds around the rocks.

Explanation:

Metamorphic rock is formed by pre-existent rocks (igneous and sedimentary, sometimes from another metamorphic rock), those rocks were modified by the effect of heat (high temperature), pressure (under the terrestrial surface) and chemistry compounds around the rocks. The physical and mineralogical composition becomes different than the original form.

This process is called metamorphism.
