...THE SCIENCE OF BIOLOGY WHAT IS BIOLOGY? Literally means “study of life” The science that deals with structures, functions, and relationship of living things and their environment. A broad science that can be studied in various levels – molecular, cellular, organismal, population, community, or ecosystem BASIC STRUCTURE OF SCIENCE Biology has evolved as a field of science since it was first studied in ancient civilizations Science is a process that requires the testing of ideas using evidence gathered from the natural world. Science is iterative in nature and involves critical thinking, careful data collection, rigorous peer review, and the communication of results. Science also refers to the body of knowledge produced by scientific investigation. SCIENTIFIC METHOD Refers to the working habits of practicing scientist. Involves rigorous application of common sense to the study and analysis of data. Refers to the model for research developed by Francis Bacon (15611626) SCIENTIFIC METHOD a. Observations - lead to questions that require answers. b. Hypothesis - a testable statement proposed to answer a question. c. Experiments - (often with controls and variables) are devised to test hypotheses. d. Analysis of the results of an experiment will lead to the hypothesis being accepted or rejected. SCIENTIFIC REASONING Inductive Reasoning from specific observations to broader generalization & theories. “bottom-up”...

...when discussing about living and non-living things. They are mostly specific on living things such as cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development and adaption through evolution. Things which have these characteristics are called as living things and things which haven’t are called as non-living things. On certain occasions we can identify living things that miss one or several characteristics from the list. For an example trees don’t show direct movements, just only the growth movements, neurons don’t reproduce, the animals that have non sexual reproductive system and the trees which are reproduced by propagation don’t show adaptations or evolutions. Importantly, some non-living things too show one or several characteristics that defines life. For an example if we think about computer it’s a logical machine, it consumes electricity. So it shows metabolism, it control its’ temperature. That’s homeostasis. It responses to stimuli. Every day its’ storage memory grows bigger. So it shows the growth. If we think about a vehicle it shows clear movements, it needs fuel to run. So that’s metabolism. While driving wheels turn where ever we turn the steering wheel. So that’s a response to stimuli. When we think about sun via nuclear reactions it gains energy. That’s metabolism. Consider about water, it floats; actually a movement. So it’s a living characteristic. 2. Snail is a living organism while a rock...

...Merth Undefined sample was found on a new planet called Merth. New sample from that new planet shows characteristics of life. This living thing is made up of units called cells. Other characteristics of life is reproduction, have DNA, grow and develop. Also living things obtain and use materials and energy, respond to their environment, maintain a stable internal environment and change over time. In order for a sample to be a living thing it needs to have those characteristics of life. Since the sample have those characteristics of live it can be classified and a living thing. One of eight characteristics of live is that is shows evidence of cellular organization. The sample dose shows evidence of cellular organization. In the sample there is vacuole which store material such as water salts and proteins. Other organelle is cell membrane which regulate what enters and leaves the cell. Also the living organelle is multicellular...

...Characteristics of Living Things Objective: 1. Identify the characteristics of living things. 1. Living things are highly organized, from the smallest part to the largest. On the chemical level: atoms make up elements. Each element has a specific number of electrons that orbit the nucleus. In the center of the element, the nucleus has protons and neutrons. The number of protons in an element is always equal to the number the electrons. The number of neutrons may vary to make isotopes of that element. Elements come together to give up, accept or equally share electrons to make molecules. The smallest part of an organism is a cell. Some single-celled organisms are free-living and contain structures, called organelles that allow them to be self-sufficient. More complex organisms are multicellular. In the case of a human, cells are organized into tissues. These have a common function like a muscle. Tissues are organized into organs like the heart. Organs are organized into organ systems, like the cardiovascular system. Organ systems functioning together make up a living organism. A population is an organization of more than one individual. This is generally all of one species in a particular area. We could talk about the population of squirrels in our area or dogs or cats. Enlarging our view, next comes a community. An example of a community is the town or place we live. A more accurate biological description would include all the living things in that area. A community is composed...

...Introduction to Personality Introduction to Personality As organisms are born there are certain characteristics that make them unique and different from any other organism. These characteristics are what make their personalities. The personality is an inner part of the organism it comes from within the organism and is not so much developed from the environment. As the organism develops and grows into themselves these characteristic s continue to surface in the organisms life because it stays consistent with whom the organism is as a whole. The behavior is different for the organism than ‘any other organism that may be classified in the same group of life. The definition of personality is the behavior, characteristic patterns and the thoughts of the organism(Hall, 1957). As the organism begins to mature in age these patterns continue throughout the life of the organism(Feist & Feist, 2009). In order to recognize the behavior; or personality of an individual you would have to observe those behavior that remain consistent throughout their life. Personality is demonstrated in any living organism not just human beings anything that is living that has a will. The will in the living organism is where the organism decided in their response to any giving situation in life. All of the living organism also act off of their personalities when needed and none of the personalities are the same and do not have the same actions (Hall, 1957).You can tell how a person...

...What Is a Living Thing? Living things are systems or organisms that tend to respond to changes in their environment and inside themselves, in such a way as to promote their own continuation and longevity. These are the ones that have the ability to breathe or respire, can move or navigate and consequently have the ability to multiply. These living things include human beings, plants, insects, animals among others. A living thing is defined as using all of these qualities: movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition. Only living things, and all living things, have these functions. A living thing is any organism that displays all the characteristics of life. These include being able to grow and use energy. They must also consist of at least one cell. You can find more information here: Theme #1 - Cells All living things are composed of one or more cells. Different types of cells have different "jobs" within the organism. Each life form begins from one cell, which then will split. These cells split, and so on. After this has happened several times, differentiation is undergone, when the cells change so that they are not the same thing anymore. Then they are used to begin to put together the final organism, some cells, for example, as the eyes, some as the heart, etc. The only arguable exception to this is viruses. They are not composed of cells, but are said to be "living." Theme#2 - Organization Complex organization patterns...

In the year 2001, we are living in the garden that is embedded with various scientific stuffs. Let’s just take a look at my life. Few years ago, I used the typewriter to write papers. Now, I am using a computer to write the paper. In the morning, the alarm clock wakes me up. I turn on the faucet to get water to brush my teeth. I pour out already brewed coffee from programmed coffee maker. I drive a car to get to the places. I wash my cloth in washing machine and dry them in the dryer. I don’t wear eyeglasses anymore because I am wearing contact lenses. Furthermore, this winter break, I am planning to have Lasik operation to correct my vision permanently. Then, I could say goodbye to my contact lenses. This is the sketch of my life, but just a part. I am living in the garden with full of scientific devices that I could no longer live without. Wow. How did we get here from the Garden of Eden to the Garden of Science? What makes the world to become such a science oriented society? What drives human beings to seek scientific knowledge of the world? Since I am a Christian who confidently believes in God’s creation of the world according to the Bible. I believe that it is a natural characteristic of the human being to seek more knowledge. The desire for more knowledge...

...Assignment 3 Part 1 1. Viruses are both living and non-living as they share characteristics of both. A major non-living characteristic is that viruses do not have cells and cannot reproduce on its own. However, the virus can reproduce if it has a living host, which gives viruses their living characteristics. 2. Viruses cannot be grown agar as bacteria are because they cannot metabolize on their own. They need at least one host cell where it could input its DNA and infect it. After that, both those viruses would commence by infecting other living host cells. 3. Antibiotics work to get rid of the replicating function of bacteria so it cannot spread. However, viruses cannot replicate on their own unless they have living hosts, therefore since the viruses do not replicate, the antibiotics have no use. 4. Viral specificity means that the virus chooses and selects the type of cell, organism to infect and which disease to invoke onto it. 5. a) A-Virus, B-Cell DNA, C-Cell/Cell Membrane, D- Nucleic Acid (DNA or RNA) b) Bacteriophage Life Cycle c) I believe it doesn’t matter what they infect, as they are non-living and as long as they find some kind of living host, they’ll inject their nucleic acid to replicate into many more viruses. 6. Antibiotics literally will have no effect and will not cure the patient. All that the patient will gain are the side effects, for example: drowsiness and such. They will not get cured, as their problem is that viruses...

...1) How is the human person’s knowledge of things related to the worship of God? Answer in light of both Pieper and Balthasar. At the core of both Pieper and Balthasar’s reasoning lies the notion that there is an inherent quality within all that is considered being. This inherent quality is referred to as truth. As Pieper states, “things are true because of their essential reality of being. Regardless of whether one is religious, or believes in God, or has any proclivity towards matters of belief, a person can intellectually deduce and know the following axiom alluded to above: “a thing cannot have being without equally having truth.” Because the aforementioned axiom is knowable by the human mind, Pieper states, “every being, as being, stands in relation to a knowing mind.” Thus, humans are able to know beings, to know things, of both an animate as well as inanimate nature. This point is critical, as it implies there is a connection between the human mind and things through an intelligible process. On the surface, the concept of truth affirms that there is something special present in the existence of a given thing. However, upon further review, this truth is in fact indicative of God, the One who has created and creates all things. The privilege of being the creator of some object is that the creator will know that object far better than an object not created by them. As an example, an auto mechanic will know the car he built far better than the car he did not build. In...

...Name: Mary Joy Elibada Date: September 14, 2014 Topic: Genetically Modified Organism Genetically modified organism is an organism whose genetic material has been altered during genetic engineering techniques. Organisms that undergo in the processes of genetic engineering enables to change its characteristics from its original characteristics. Insects, plants, fish, mammals, bacteria and yeast are the organisms that can be genetically modified. Genetic modification is used to manipulate, remove, add or change the genes of an organism to achieve the desired characteristics. If there is organism that needs to be improve, we can use other organism even if they are in different specie, and get its genes to be implant to the first organism that can finally achieve the desired traits. In result we made a new organism. We can apply the idea of genetic modification in the plantation of fruits and vegetables. For example, there are plants that can’t resist extremely cold temperature in a long period of time like tomatoes, that can result in decaying of tomatoes that cannot be sell anymore. This is what scientist where able to change the genetic modification. They figure out a way to take DNA from one organism and put it inside the completely different organism to create a desired specific outcome. We can get genes from an arctic fish that can stand in a very low...
