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 that govern all study and research‚ consolidating it into single‚ coherent field. In general‚ biology recognizes the cell as the basic unit

"Indians" By Jane Tompkins: How Bias Affect Ones Concept of History Whenever you are in any educational situation‚ you are subject to perspectives and bias of the instructors. In an essay entitled "Indians‚" by Jane Tompkins‚ it discusses how different biases may reflect upon one’s concept of history. It is imperative to realize that when learning‚ which generally involves someone’s concept of history‚ we are consequently subject to that person’s perspectives that may be a result of

CHAPTER # 1 Q.DEFINE CHEMISTRY. A. Chemistry‚ a branch of physical science‚ is the study of the composition‚ properties and behavior of matter. Chemistry is concerned with atoms and their interactions with other atoms‚ and particularly with the properties of chemical bonds. Chemistry is also concerned with the interactions between atoms and various forms of energy Q.DEFINE THE BRANCHES OF CHEMISTRY. * Physical chemistry is the study of macroscopic‚ atomic‚ subatomic‚ and particulate phenomena

Gymnastics Vault and floor focus on energy conservation and motion in different dimensions. Before a vault or a tumbling pass‚ I start by running (about 60 feet for vault and 15 for floor) trying to attain maximum speed and acceleration right before I begin the first part of the skill. On vault‚ I try to be as efficient as possible in my hurdle to the springboard and transfer to the table‚ which I then push with my arms and shoulders to get one more energy boost before flying off the table.

Experiments investigating the effect of a particular factor on an enzyme-catalysed reaction are commonly used as assessed practicals in Biology. The reason for this is there are a number of factors that can be investigated‚ and therefore‚ a number of factors that can also be controlled. From our lecture‚ we are aware that the following can affect the rate of reaction: 1) Temperature: a. Independent variable: A range of temperatures should be investigated‚ with particular attention

founded a new branch of life science‚ evolutionary biology. Four of his contributions to evolutionary biology are especially important‚ as they held considerable sway beyond that discipline. The first is the nonconstancy of species‚ or the modern conception of evolution itself. The second is the notion of branching evolution‚ implying the common descent of all species of living things on earth from a single unique origin. Many people are familiar with how Darwin came up with the theory of evolution. Darwin
