1. I believe that these polymers, Cellulose, starch and glycogen have different properties because they are used in different organisms. Cellulose and starch are mainly used in plants and glycogen is used in animals. Cellulose is used for strength in its stems and leaves and uses starch for help with storing things. Glycogen is used in animals to help store things as well. These polymers have different properties because they have different functions in different organisms.

2. Diffusion is the spreading out of particles from an area of high concentration to an area of low concentration. This is similar to the effect of an aerosol spray can. All the particles are tightly packed in the can and when you release them they flow into the air and diffuse where there is more area and less of the particles or a drop of dye into water, once the water has turned the color of the dye it has been diffused. Osmosis is when something crosses a permeable membrane from areas of low concentration to high concentration. This usually involves water of some sort. Active Transport is when a substance us...

Analysis and Description of Synthetic Biology Essay

- Synthetic biology, “the aim is to create improved biological functions to fight current and future challenges”. Like all engineering disciples’ synthetic biology is motivated by application to solve specific problems” (3, 7). “Like chemistry biology is the study of living things. Synthetic biology is replicating and recreating nature, which allows it to sometimes control living things (6). Larger quantities of Artemisinin a drug for malaria will be due to the new E coli strain. Thoughts are that it may be able to produce food, optimize industrial processing and detect, prevent and cure cancer (1, 3)....   [tags: synthetic biology, dna, cells]

Essay on Zoology Biology Quiz: Arthropods and Worms

- Annelids: I learned that the phylum Annelids can consist of many creatures such as earthworms, leeches, and scale worms can adapt to a variety of environments. Annelids’ bodies are divided into segments which are seen as rings by the naked eye. They have muscles which help them move by contracting their longitudinal and circular muscles. When Annelids take in food, the food particles travel through one end of the body and are excreted out the other side. The video enhanced my understanding about Annelids because without seeing different species and what classified them as Annelids I would have never known an earthworm or a leech fell into that phylum....   [tags: Annelids, Chordates, Insects]

A Comparison of Eukaryotic and Prokaryotic Cells Essay

- A Comparison of Eukaryotic and Prokaryotic Cells There are two main types of cells in the world. The simplest cells such as bacteria are known as Prokaryotic cells, and human cells are known as Eukaryotic cells. The main difference between each of these cells is that a eukaryotic cell has a nucleus and a membrane bound section in which the cell holds the main DNA which are building blocks of life. Prokaryotic cells do not have a nucleus. The chromosomes which are found in prokaryotes are usually spread in the cytoplasm....   [tags: Biology, Cells, Science]

Different Types of Stem Cells Essay

- Stem cells have the ability to grow and multiply into many different cells in the early life of the body. Stem cells help to replace dead and or damaged cells in the human body. These stem cells are found inside the body, inside our organs and tissues such as in our skin and liver. Each stem cell helps its organ or tissue such as if the liver is damaged, the liver stem cells would repair the liver. There are four main types of stem cells: adult, fetal and embryonic. Each of these stem cells acts in a different way and have their own nature....   [tags: biology, cells, organs, tissues]

Biology Notes regarding Cells and Related topics Essay

- 1. The ability of ice to float because of the expansion of water as it solidifies is an important factor in the fitness of the environment. If ice sank, then eventually all ponds, lakes, and even oceans would freeze solid, making life as we know it impossible on earth. During the summer, only the upper few inches of the ocean would thaw. Instead, when a deep body of water cools, the floating ice insulates the liquid water below, preventing it from freezing and allowing life to exist under the frozen surface....   [tags: Biology Study Tests]

Practical Applications of Evolutionary Biology Essay

- Charles Darwin and Alfred Wallace's concept of natural selection and descent with modification helped shape the theory of evolution which holds as much weight as the theory of relativity per se. Evolutionary biology is the science devoted to understanding how populations change through time in response to modifications of their environment and how new species come into being by studying adaptation and diversity (Freeman and Herron 2004). Evolutionary biology has proved that all organisms have evolved from a common ancestor over the last 3.5 billion years....   [tags: Biology]

Plant And Animal Cells Essay

- Plant and Animal Cells I. Introduction All organisms in life are composed of at least one or more cells. Cells are the basic units of life. There are three main features of a cell. First, all organisms consist of one or more cells. Second, cells are the smallest units of life and third, cells arise only from preexisting cells. These three facts are referred to as the cell theory. All cells can be categorized into two basic cell types. They are prokaryotic and eukaryotic. To distinguish where cells are placed in the two categories, what is inside the cell must first be looked at....   [tags: Biology Biological Cells Essays]

Biology Essay

- Biology is the science of living systems. It is inherently interdisciplinary, requiring knowledge of the physical sciences and mathematics, although specialities may be oriented toward a group of organisms or a level of organization. BOTANY is concerned with plant life, ZOOLOGY with animal life, algology with ALGAE, MYCOLOGY with fungi, MICROBIOLOGY with microorganisms such as protozoa and bacteria, CYTOLOGY with CELLS, and so on. All biological specialties, however, are concerned with life and its characteristics....   [tags: Biology]

Biology Essay

- Lab Report 1 Principles of Biology 1(BIOL 100) Fall 2001 Gerard Chretien Living cells perform a multitude of chemical reactions very rapidly because of the participation of enzymes. Enzymes are biological catalysts, compounds that speed up a chemical reaction without being used up or altered in the reaction. The material with which the catalysts reacts, called the substrate, is modified during the reaction to form a new product....   [tags: essays research papers]

Biology Essay

- Biology 1. The virus is made up of five parts and is in the size range of 10 nm-300 nm in diameter. The first is the coat made up of protein that protects the virus to a point. Next is the head that contains the genetic material for the virus. The genetic material for a virus is DNA. The two other parts are the tail sheath and the tail fibers that are used for odd jobs. I believe that a virus is not considered to be a living creature due to the fact it is a parasitic reproducer. To me it is just like ripping up a piece of paper because it is still the same thing and it isn't carrying out any other function besides reproduction....   [tags: essays research papers]
