A General Overview of Biology

Marine Biology is the scientific study of organisms in the ocean or other marine bodies of water. Marine Biologists are the examiners of this science. Marine Biologists play an important role in today’s society because 71% of the Earth is made up of water and only 5% of water on Earth has been discovered (“Ocean”). Without having these scientists in our communities today, the largest part of Earth would remain a mystery. The process of becoming a Marine Biologist is no easy task. It requires years of hard work and dedication through school work and lots of studying on your free-time. Marine Biology is easily one of the most impactful jobs in today’s society.

Biology is a broad field, covering the minute workings of chemical machines inside our cells, to broad theories of ecosystems and global climate change.

The study of biology is relevant now because it has everything to do with life and life is everywhere on Earth. We can use biology to keep that from changing. Biology has helped us grow food, protect the environment, tell us how the body works, and so much more. Thanks to biology viruses and diseases can also be controlled. Biology has advanced the world so much and without it everything would be completely different.

A deep-sea scuba diver is approaching the bottom of the Great Barrier Reef in Queensland, Australia when all of a sudden she sees an Indo-Pacific humpback dolphin swimming on her right. The diver turns around to see a dwarf minke whale on her left. These are just two of the various amazing marine creatures that a marine biologist could encounter whilst simply doing her job. Marine biologists are biologists who study saltwater animals and plant species. Not only are they collecting and analyzing data about marine life, they are raising attention about problems to try to protect the environment (Greenland and Sheldon). However, working in fieldwork can be very physically demanding and marine biologists have to cope with deep-water pressure and walking long distances. Also fieldwork assignments can be very long and last up to weeks at a time (Greenland and Sheldon). Being a marine biologist can be a very unique and amazing experience traveling to rare regions to study marine life, although it can be very dangerous and time consuming.

I knew that they worked with animals and that they studied the oceanic environment. They work on in the ocean and on land, depending on the task they work in groups or alone. Also, with marine biology I feel like one of my strengths is that I love being around the ocean and I love working with people.

Explain what biology is and describe its major branchesAccording to wisegeek, Biology is the scientific exploration and study of life. Biologists study the structure, function, growth, origin, evolution and distribution of living organisms (livescience). In fact, the origin of the word biology comes from Ancient Greece, from the Greek word “bios” meaning life and “logy” meaning study (oxforddictionaries). There many divisions of biology, but all of them can fit under the “umbrella” of three different studies, Zoology, Botany, and Microbiology (wisegeek). Respectively, Zoology studies animals, Botany studies plants and fungi, and Microbiology studies microorganisms, like bacteria sometimes things that don’t fit under the group of living things, like viruses (wisegeek).

The need for the new changes is something that should had been in place a long time ago. There can be no way society thinks America is being over protective. If this great nation that is called home to more than 300 million people not being alert and ready for anything, it will not be here much longer. The rules that are in place due to the 9\11 acts woke America up…now stay up America!

In chapter one of Essential Biology by Campbell summarizes how the world operates, the way organisms operate and the different cells that make up an organisms . Chapter one also speaks about Darwin’s theory of survival of the fittest and lastly the process of the scientific method. Firstly there are seven properties to which we associate with life. Order is one of the main properties of life because without any order our bodies would not be able to function properly. Different cells

Biology helps you to understand the human body and how it works. Biology is a fascinating subject which can help you to understand the relationship between hypotheses, evidence, theories and explanations.

Physiology: The branch of biology that deals with the normal functions of living organisms and their parts.

Definition: Biology is how the genetic predispositions, hormones, biochemistry, mental and physical makeup have encouraged or discouraged the behavior/topic. (Gunhus, minilecture 1 pg. 6).

Biology is the study of life, and there are four main ideas in the field of biology: Evolution, Free Energy, Information, and Systems. Evolution has five main concepts including natural selection, small sample size, non-random mating, mutations, and immigration & emigration. Contrary to popular belief, Darwin did not “invent biology” rather he created a way to explain natural selection, and defined Biology as “the tool that allows organisms to become better adapted to their local environments.” He also believed that all life shares a common ancestry, otherwise known as macroevolution. Free energy is the energy that is available to do work. The energy flowing from the sun to the earth, which is used is by plants for photosynthesis and respiration is such energy. Homeostasis, which is the maintenance of a strong internal environment, is key in dealing with free energy. Information is the importance of DNA and cell communication. DNA is what makes RNA and is located in the nucleus, and the RNA makes proteins, which are used to build organisms. Lastly, cell communication is cells transferring information whether using hormones or nerves. Biology is built on hierarchies of systems, such as carbon compounds, macro molecules, organelles, cells, tissues, organs, organ systems, and so on.

A marine biologist is a person who studies all different types of sea animals and plants and study marine animals. They can choose to specialize in studying large ocean animals. Everything from whales to the plankton that they eat, and everything in between, they can study. They also help keep the animals safe. One area of specialization, the field of marine biotechnology, offers great connection for marine biologists. The job responsibilities are that people can rely on you to be there to help. You will have to study sea plants and animals, and indirect problems that affect them. Also, to review reports and analyze data.

The cell is the most basic form of life essentially. Anything that is living fundamentally is composed of cells. We study the cell because it is the simplest unit of all living organisms and to begin understanding life, we must realize the cell’s structure, whether it is about the different types of cells or how the cell functions. Biology is the study of life and for the human species; the cell is the most basic principle of life, which is why it is so important to understand the complexities of cells.

Life is defined by all the living creatures on earth. Biology is a broad topic of the study of life. Biology contains many different types of subjects within it that may be studied, like terrestrial or aquatic animals, or viruses and diseases. Here I will be talking about twelve of the millions of parts: Characteristics of life and kingdoms, biomolecules, nature and the importance of water, cells, energy and the carbon cycle, cell division through mitosis and meiosis, the central dogma through DNA/RNA and proteins, genetics and inheritance, evolution, energy through food webs and food chains, symbiotic relationships, and human impact.
