We use samples to perform experiments. When sampling, we take test subjects from a larger group often known as "<em>population</em>" or at times "<em>universe</em>".
Sampling is a term we use to describe the process of selecting a small representitive group from a larger population. Sampling can often be divided in its simplest form into:
- <u>Random Samples</u>
- <u>Non-Random Samples.</u>
Which as their names imply, represent first a sample that is chosen by not specific method and whose probability is equal for the entire <em>population</em>, and secondly a sample chosen based on specific parameters.
Sampling can then become more complex, being divided into more complex methods such as:
- <u>Systematic sampling
</u>
- <u>Stratified sampling
</u>
- <u>Cluster sampling</u>
etc.
The one thing all of the sampling methods have in common is the fact that they will all draw their samples from one place. This place or aspect from which samples are drawn is known as the <em>population</em> <em>group </em>or sometimes coined as the <em>universe</em>, to represent the group in its entirety.

Thorns
Explanation:
<span>The answer is I, II and III. These
microbes can be funds even in hydrothermal vents at the bottom of ocean
trenches where they convert chemicals to organic matter. Most are critical in
the many nutrient cycles such as the nitrogen and carbon cycles. These microbes form the
base of the food chain since they support higher organisms such as paramecium
which are in turn eaten by higher organism such as amoeba. The amoebas are then
fed by tadpoles, for example, and the tadpoles are eaten by fish…and etcetera. </span>
Answer:
A medida que se desarrollan más técnicas en Biología Celular, conocemos más acerca de los grandes misterios y secretos que encierran las células. Conocer las células vegetales y animales es muy importante para entender el funcionamiento de los seres vivos, entender las enfermedades que sufren, desarrollar técnicas terapéuticas contra estas enfermedades u obtener productos de interés comercial.
