Biology: Animals


The order of what the universe is made up with is:
• Quark
• Neutrons, Protons, and Electrons
• Atom
• Molecule
• Cell
• Tissue
• Organ
• Organ System
• Organism
• Population
• Community
• Ecosystem
• Biome
• Biosphere
• Solar System
• Galaxy
• Universe


In life, everything is made up of something and makes something. The start is quarks, and scientists are still trying to figure out what they are. Quarks make up neutrons, protons, and electrons. Neutrons, protons, and electrons make up atoms, and atoms make up molecules. Molecules make up cells, which is the basic unit of structure and function in living things. Cells are grouped together to form tissue which has a specific job in the body. Tissues combine to form an organ, which performs a more complex job than each tissue by itself. Organs combine to form an organ system, which has a broad function in the body. Did you know that there are ten major organ systems in the human body? Imagine how many cells that is! Next, all of the organ systems in the body make an organism. Many organisms make up a population, and populations make up a community. Communities make ecosystems, and ecosystems make up biomes. Biomes make up a biosphere, and biospheres make up a solar system. Solar Systems form galaxies and galaxies form universes. So in the end you can assume that quarks make up the universe. Quarks are “seen” as elementary particles, therefore based on this order, the universe must be made up of millions of elementary particles. To find more in-depth information on quarks see the links below. In my opinion, I think it would be fascinating to figure out if quarks come from or are found in the universe. That would mean, rather than a list of everything making up the universe it would become a circle, where everything came back to each other. Also, I hope that someday scientists learn what is really smaller than a quark because it would be really interesting to find out if it is possible for that to happen or if a quark is really the smallest thing in the universe.


Another biology fact is that scientists classify animals into major groups called phyla. Each phylum has different characteristics. When doing this they consider an animal’s body structure, the way an animal develops, and the animal’s DNA. Phyla help scientists observe each animal and compare it with animals that are alike with it. Personally, I feel this is a great idea. Though invented a long time ago, it is helpful to us even now. For example, if scientist finds a new species, they can easily find out where the animal belongs, and what animals it is similar to. Also, the similar DNA certain animals in phyla share might convince scientist they were made from a similar ancestor. So, if they see what that animal is related to and continuing on and on with the process they could eventually end up going back to where all animals rose from: a single celled organism. Overall the use of phyla is very interesting. For some example of phyla, look at the sites listed below.


In general, biology very complex and has many parts to it. You need to know the simple facts to move on to everything else. This is just the start of biology and more information is headed toward the future.
