AP Chemistry is a course geared toward students with interests in chemical biologies, as well as any of the biological sciences. The course aims to prepare students to take the AP Chemistry exam toward the end of the academic year. AP Chemistry covers most introductory general chemistry topics (excluding organic chemistry), including: Reactions
The term "biobank" first appeared in the late 1990s and is a broad term that has evolved in recent years. [1] [2] One definition is "an organized collection of human biological material and associated information stored for one or more research purposes."
In analytical chemistry, sample preparation (working-up) refers to the ways in which a sample is treated prior to its analyses. Preparation is a very important step in most analytical techniques, because the techniques are often not responsive to the analyte in its in-situ form, or the results are distorted by interfering species .
Sample sizes may be evaluated by the quality of the resulting estimates, as follows. It is usually determined on the basis of the cost, time or convenience of data collection and the need for sufficient statistical power. For example, if a proportion is being estimated, one may wish to have the 95% confidence interval be less than 0.06 units wide.
In general, a sample is a limited quantity of something which is intended to be similar to and represent a larger amount of that thing(s). [1] The things could be countable objects such as individual items available as units for sale, or an uncountable material.

Importance: This massive text by outstanding research workers begins with simple systems and proceeds logically to the more complex phenomena of physical chemistry. The original literature is cited extensively, making the work useful as a reference as well as a textbook. Many topics of current research are treated.
In AP Research students design, plan and conduct a year-long research-based investigation on a personally-chosen subject. The assessment culminates with a 5,000-word academic thesis paper, as well as a public presentation. Students must obtain a final score of 3 or higher to be able to receive AP certification. [1] As of the 2017–18 school ...
