“Microcosmos”, by Wislawa Szymborska, explains how understanding bacteria expanded human’s understanding of the universe. Throughout the poem, she draws comparison between how small humans are in the vastness of the universe, and how bacteria are so small compared to humans. Szymborska depicts human existence as insignificant when compared to the massive scale of the universe in her poem, “Microcosmos”.

Microbiology is the study of microorganisms found in all different environments throughout Earth, from the hot thermal vents at the bottom of the ocean to the ice at the top of a mountain. These microorganisms are used to teach us how multicellular organisms came to be and how they can survive today. These small, microscopic organisms are so unique that the identification of them is paramount in the advancements of science. Knowing the chemical makeup, the shape, and the biochemical processes is important in identifying these organisms to understand how they survive and where.

1. Free ears in dogs are controlled by dominant allele (F), and attached ears are controlled by the recessive allele (f). In addition, Short dogs is due to a dominant allele(S), and long hair is due to a recessive allele (s). Which of the following is the genotype of the dogs with free ears and short hair?

The next system I dissected was the respiratory system. My first task was to find the trachea as well as the esophagus. My goal was to compare the structure of each. I found the trachea to be wider, stronger, and it had a bumpy surface. The structure of the esophagus is small, but versatile which allows it to move easily. It is also flat and full of muscle. This allows for food to digest before it enters the stomach. While dissecting the respiratory system, I continued to study the trachea, as well as the lungs and bronchi to see how their structure related to their function. . As mentioned above, the trachea is a wide and strong part of the respiratory system. The structure of the trachea is related to the function because it allows for the fetal pig to receive proper air passage through the lungs. Next, the structure of the lungs consist of four lobes in the right lung, and two or three lobes in the left. “The lungs in the fetal pig are small and fairly solid because they’ve never been

Spongy bone also knowns as cancellous contain red and yeallow bone marrow. Red bone marrow produces roughly 200 million of red blood cells (RBC) per a day. Yellow bone marrow contains primary fat cells. This can be transformed into red bone marrow to provide RBC if needed (Ivy Rose Holistic,n.d). The sponge is light and have low density which balance the heavier parts of bone. Sponge tend to form a long line of stress which gives strength and flexibility in that area (Biology dictionary, n.d). articular cartilage is smooth elastic tissue which decreases friction and distribute load. Cartilage exhibits stress-shielding of the solid matrix components due to its high-water content, the incompressibility of water and the structural organization of the proteoglycan and collagen molecules (Derek Moore,n.d). Epiphyseal line is area of developing tissue and everyone has at least two, one at each end of bonePeriosteum is outer membrane which contains connective tissue, nerves and capillaries. It allows blood in and out of bone and help with growth and repair (PubMedhealth,n.d). compact bone provides the strength and protection of bones. It provides strong mechanical layers which with

Lumbriculus variegatus, also known as blackworms, are relatively small specimen. Their physiology is so simple that the organisms lack a respiratory system and heart. Henceforth, blackworms rely on diffusion in means of gas exchange through their tail segments and muscle contractions of the dorsal blood vessel (Laboratory Manual BIO 10200, p.69). The circulatory system of the blackworm is closed containing arteries, veins and a muscular pumping dorsal vessel which contracts enabling blood to be moved from the posterior end, where gas exchange occurs, to the anterior region, the head of the

We never underestimate the power of an itsy-bitsy atom, which contrives the mysterious, gigantic universe. The analogously minuscule cell is regarded true biological atom, which institutes many intricate systems of our complex human body and its creation, my inheritance genes provoked my inquisitive mind to dive into the understanding of the complexity of our organs.

When Jeremy Stone discovers the structure of the microorganism, he notes how it is structured, but in a nature vastly different from any forms of

We then observed each cell one by one under the microscope at x4 magnification. We wrote down characteristics of the cells we saw; not much was able to be determined except for basic structure i.e. cell wall, no cell wall, or cell membrane and was it able to move at all.

Red marrow is so valuable because it is where blood stem cells are found. Bone broth rich in red marrow provides those stem cell factors which ultimately build your body’s strength and support your immune function

Bones are living tissue composed of living cells because of this they are a complex source of a wide variety of nutrients. They contain minerals which are embedded in protein, fat and fat soluble vitamins. They are a great source of calcium, copper, iodine, iron, magnesium, zinc, and manganese. The central part of most bones contain marrow which is a highly nutritious source of blood forming elements. They also provide natural antioxidants including enzymes. Pets fed bone rarely suffer from indigestion or diarrhea. Bones play a similar role to fiber which helps remove toxins promoting bowel health. Pets fed bones are long lived healthy animals that seem to be particularly free of degenerative diseases. Common bones can include chicken backs,

Mesothelioma is a type of cancer that affects the lining of the lungs and the abdomen. It is one of the less common types of cancer affecting approximately 2000 people each year in the UK and it is almost always caused by asbestos exposure. If it affects the lining of the lungs (the pleura) it is referred to as pleural mesothelioma. In this article I will be outlining three of the most common symptoms for this type of cancer and explaining what you should do if you suspect you have developed this condition.

Can any other planet besides Earth be habitable? The Earth has to have many essential elements for it to be able to attain human life. Some of these key elements include our placement in the solar system, our tilt, oxygen, food, the magnetic field, etc. Because of these perfect conditions, Earth is livable. Our planet, Feuer Leava, is habitable because of its place in the solar system, its atmosphere, and its formation.

The Hot Zone is a nonfiction story written by the unique author Richard Preston who won several awards because of his outstanding style of writing. Briefly, this narrative describes how the Ebola Virus diffused from the rainforests of Africa reaching the suburbs of Washington, DC in 1998 using an attractive language that fosters imaging and imagining. To be more accurate, it highlights the issue of an epidemic lethal virus and its outbreak. In this report, I will write about two medical subjects that are mentioned in the book related to the microorganisms’ world: Viruses and Bacteria which share some similarities but vary from one another.

The majority of cells making up the human body are diploid cells carrying identical DNA, with the exception of haploid gametes and red blood cells. Several types of biological evidence such as blood and hair are commonly used in forensic science, which is the scientific study of evidence for crime scene investigations and other legal matters. Forensic science is used for the purpose of DNA analysis, this is the analysis of DNA samples to determine if it came from a particular individual. DNA analysis is done by obtaining DNA samples from an individual; next, a large sample of DNA is produced from amplified selected sequences from the DNA collected. Finally, the amplified DNA regions are compare using a gel. DNA Profiling
