Answer:
1. It reduces the probability of sampling bias.
2. A random sample will be more representative of the whole population.
3. Allows the researcher to determine the efficacy of the fertilizer.
Explanation:
Selecting a simple random simple from a large population is a widely used method in science. Researchers select a random sample so every individual, in this case seedling, has an equal chance to be selected.
Therefore, it is an accurate method that, although is not free from errors, avoids or reduces the probability of sampling bias. Selecting a truly random tomato seedling will be more representative of the whole population of seedling instead of selecting carefully a seedling that already has specific or desired characteristics. Hence, this random sampling will allow the researcher to determine the efficacy of the fertilizer.
Informal means of control – Internalizationof norms and values by a process known as socialization, which is "the process by which an individual, born with behavioral potentialities of enormously wide range, is led to develop actual behavior which is confined to the narrower range of what is acceptable for him by the group standards."[2]
Formal means of social control – External sanctions enforced by government to prevent the establishment of chaos or anomie in society. Some theorists, such as Émile Durkheim, refer to this form of control as regulation.
As briefly defined above, the means to enforce social control can be either informal or formal.[3] Sociologist Edward A. Ross argues that belief systems exert a greater control on human behavior than laws imposed by government, no matter what form the beliefs take.
Social control is considered one of the foundations of order within society.
Answer:
Another effect of the spread of Islam was an increase in trade. Unlike early Christianity, Muslims were not reluctant to engage in trade and profit; Muhammad himself was a merchant. As new areas were drawn into the orbit of Islamic civilization, the new religion provided merchants with a safe context for trade.
Answer: dry scrubbers are less than 10% efficient at removing particles less than 1μm in size
Explanation:
A dry scrubber or dry scrubber system is one type of scrubber that is used to remove harmful materials from industrial exhaust gases before they are released into the environment. That substance then falls out of the gas stream or is caught in a particle screen.
