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.

There are several "downsides" to extensive use of synthesized nitrogen-containing fertilizers; it contributes to algal blooms and dead zones in bodies of water, nitrogen is usually considered as a highly effective and economical fertilizer. However, the repeated use of the chemical can cause an imbalance in the pH of the soil, eventually leaving it unusable for growth of any kind.
<em>Answer:</em>
<em>Rain forests recycle nutrients. (Apex)</em>
<em>Explanation:</em>
<em>Plants can convert atmospheric carbon dioxide to other carbon based compounds through photosynthesis. Rain forests are the largest carbon revisers and are responsible for most of the oxygen in the atmosphere </em>
<em>
</em>
<em>Basically they take in carbon dioxide,convert it to oxygen and then release the oxygen back into the environment. Thus helping to prevent the plant from heating up.</em>
Answer: It is then the space in which the life of living beings and the interaction between them and other things takes place. It is made up of living organisms, abiotic elements and artificial elements. It includes physical, chemical and biological components of the organisms and elements that form it. It is important because it is the place of habitat of humanity, it provides natural elements such as water and food, it provides fuels and raw materials that serve to manufacture artificial things and it contributes to the sustainability of life on the planet.
Explanation:
The environment is a system made up of living organisms (such as animal and plants), abiotic elements (lifeless, such as stones or water) and artificial elements (created by man, such as buildings) that are related to each other and can be modified by human action. <u>It is then the space in which the life of living beings and the interaction between them takes place</u>.
It includes physical, chemical and biological components of the organisms and elements that form it. That is, how is its composition and its function in the environment.
The importance of the environment lies in:
- It is the place of habitat of humanity, so it influences the life of human beings and future generations. It is the space where life develops at this time with all living beings and their natural components.
- It provides natural elements such as water and food since it offers all its natural resources needed by the human being.
- It provides fuels and raw materials that serve to manufacture the artificial things we use daily, to build houses, have light, transport, among many other benefits to exist.
- In the environment we find a great biological diversity of plants and animals that help maintain the ecological balance of the earth. This contributes directly to the sustainability of life on the planet. Each organism has a unique role to play.
Therefore, all societies must guarantee their care for their existence and make rational use of all their resources.
Answer:
Ribosomes
Explanation:
They are responsible for protein synthesis. Both eukaryotic and prokaryotic cells need proteins to live.
