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

Answer:
Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart.

The double membrane. It's theorized that chloroplasts used to be their own single-celled organism in the environment (and therefore with its own membrane). Then, the theory states, a larger cell took in the chloroplast by endocytosis, which involves surrounding the chloroplast in the large cell's own membrane. The chloroplast would then have two membranes surrounding it. This is similar to the thinking for mitochondria becoming an organelle as well. Hope this helps! :)
Answer:
Not linked
Explanation:
Linked genes don't show independent assortment.
You don't show the table...but you should see that the more complex an organism, the more chromosomes and the more genes it has.
A bacteria has a small genome. perhaps it has about 5000 genes. it also has 1 chromosome.
Yeast are more complicated than bacteria. Saccharomyces cerevisiae (the yeast that makes beer, wine and bread, has about 6300 genes and 16 chromosomes.
A human has 46 chromosomes (23 pairs), and has likely around 20,000 genes.
