Essay / Thoroughbred... he's alive! - 1263
Life. No one really thinks about it, either something is alive or it's not. Take a rock for example, you don't have to be a genius to conclude that it's not alive. However, with more complex things, like a human or an animal, we know they are alive, but we don't know exactly how or why. When we ask someone: “Is this leaf alive?” How do you know?" and they say yes, the next common answer is "I don't know, they just are!" There are seven characteristics of life that will unquestionably determine whether a subject is actually alive or not. Take by example a thoroughbred racehorse, it is obviously alive, which proves that by being made up of cells, it is capable of regulating homeostasis, of reproducing, of growing and developing, of having a metabolism , to respond to stimuli and to show biological evolution One of the characteristics of life is that the organism is made up of cells. Thoroughbreds are multicellular organisms, which means that their cells are eukaryotic and specialized. They easily demonstrate this by the lightning-fast hooves on their lower legs. They may appear indestructible, but they are not at all. They are made of living bones covered in keratin and proteins. , like collagen, elastin and fibroin, its role is to form connective tissue, bone matrices and tendons. Keratin is produced in cells and plays an important role in horns, hair, hooves and skin cells. In the specific case of hooves, it attaches and binds to the living bone that makes up their shell. Hooves are just one example of the cells they have, their internal system has millions upon millions of cells. Red blood cells to carry oxygen, white blood cells to help with immunity and also DNA cells. Second, the ability to regulate an internal system,...... middle of paper ...... is demonstrated. The thoroughbred breed originated in England in the 17th century, but quickly spread throughout the world in the 18th and 19th centuries. Native mares were crossed with Arabian, bearded and Turkmen stallions. Any modern thoroughbred can trace its pedigree back to three original stallions imported to England in the 17th century. This is the only breed that can consistently reach speeds of 40 miles per hour due to their physique. They are at least 15h but can exceed 17h with a generally solid coat, there are rarely white or palomino purebreds. In conclusion, using the seven characteristics of life is a very accurate way to prove the life of an object or organism. When studied keeping in mind the seven parts, metabolism, homeostasis, response to stimuli, reproduction, growth and development, made up of cells and biological evolution..
