Pre-Lab: Analgesic drugs are known for reducing pain‚ while antiseptic drugs reduce symptoms such as fevers and swelling. However‚ some of these drugs can reduce both illnesses. To obtain a pure compound in these drugs‚ the scientist needs to separate the desired compound by taking advantage of the different physical and chemical properties. Such as; different boiling points

Mixture that are uniform in composition‚ properties‚ and appearance throughout are called homogeneous. Sugar water is a homogeneous mixture and rocks is a heterogeneous mixture. Homogeneous and heterogeneous mixtures can be separated into their components by several physical methods. The methods that will use for the separation depend on differences in physical properties such as decantation‚ filtration‚ extraction and sublimation. The process of separating a liquid from a solid (sediment) by gently

Basic HDD Components Many types of HDDs are on the market‚ but nearly all share the same basic physical components. Some differences might exist in the implementation of these components (and in the quality of the materials used to make them)‚ but the operational characteristics of most drives are similar. The basic components of a typical HDD are as follows (see Figure 9.9): ■ Disk platters ■ Read/write heads ■ Head actuator mechanism ■ Spindle motor (inside platter hub) Chapter 9 ■ Logic

Biotic Components All living organisms depend upon their environment for survival essentials: 1) food 2) shelter 3) breeding site. In turn the organism interacts with the environment in several ways. For example a plant uses the environment for the three purposes named above but in turn it also removes carbon dioxide and water from the air‚ it gets eaten by an animal or a parasite and it depends on the soil for its support. Therefore the plant is interacting with the abiotic components and
