What is passive transport? Passive transport is the movement of substances across the cell membrane without the use of energy by the cell. During passive transport‚ substances move down their concentration gradient‚ hence no energy is required. Passive transports can happen through three different channels‚ namely 1. lipid bilayer 2. pore protein 3. carrier protein SIMPLE DIFFUSION What is diffusion? Diffusion is the movement of particles from a high density region to a low

Section 1 1. Define mutualism and commensalism. Mutualism- Both are benefited Commensalism- One benefits the other doesn’t care. 2. Give examples of mutualism. Oxpeckers (a type of bird) and Zebras‚ the Oxpecker picks ticks and parasites off of the Zebra. The oxpecker gets food and the Zebra gets pest control. 3. Explain why most parasites do not kill their host. Why is it in their own best interest to keep their host alive? If a parasite kills its host the parasite will most likely die too Section

Week 1 – Chapters 1 & 2 Why do some business firms pursue a triple-bottom-line outcome while others focus only on profit maximization? Please‚ use a real company example to illustrate your points. The triple bottom line outcome focuses on the concept where firms are environmentally conscious and socially responsible by achieving a balance between profits‚ avoiding damage to the environment‚ and achieving social benefits (Douglas‚ 2012). Traditionally‚ firms focused on profit maximization

heroes have been told‚ written‚ and passed down since the beginning of time; each unique but following a tight pattern. Joseph Campbell was the first to notice this and wrote a book called The Hero With A Thousand Faces. Campbell wrote about the similarities of every hero’s journey while breaking it down into three steps: Departure‚ Initiation‚ and Return. In his book‚ Campbell compares many old Greek myths and heroic tales from centuries ago‚ and although he focuses on ancient myths‚ modern hero stories

After years of study Joseph Campbell found that all heros travel the same path in their lives. Mr. Campbell named this famous theory the hero’s journey. The hero’s journey states that the hero’s must first endure several obstacles and if the hero passes all the obstacles he/she will be rewarded. This treacherous journey is repeated over and over again. This theory not only relates to us but it relates to everyone for instance myself. In fact my life’s journey as a football player and a grandson is

increasingly complex models at all levels of biology. This paper shows the innovations in studying biology. It discusses the biological level of organization and it also describes the model that has seem to be found on the said level. It was also discussed on this paper that the complex models that was developed for the past few years must have the new methods and techniques to model it. The journal tackles the level of organization‚ multi-scale in modelling in biology‚ MD of ion channels and heart modelling

Achmea structure taxonomy In their book Designing Effective Organizations (2002)1‚ Goold and Campbell provide a taxonomy of unit roles in order to help managers to design network organizations. In this assignment the organizational structure of Achmea‚ as presented in figure 1.1‚ will be reconstructed by using the taxonomy of Goold and Campbell. This new structure implicates the responsibilities and the reporting relationship of the different units of Achmea. An organizational

Biology is a natural science concerned with the study of life and living organisms‚ including their structure‚ function‚ growth‚ evolution‚ distribution‚ and taxonomy.[1] Modern biology is a vast and eclectic field‚ composed of many branches and subdisciplines. However‚ despite the broad scope of biology‚ there are certain general and unifying concepts within it which govern all study and research‚ consolidating it into single‚ coherent field. Biology generally recognizes the cell as the basic unit

AP Biology Study Guide Chapter 11 1. Categorize chemical signals in terms of the proximity of the communicating cells. Local signaling – a. Paracrine signaling – a secreting cell acts on nearby target cells by discharging molecules of a local regulator (a growth factor‚ for example) into the extracellular fluid. b. Synaptic signaling – a nerve cell releases neurotransmitter molecules into a synapse‚ stimulating the target cell. Long distance signaling- c. Hormonal signaling – specialized
