A representative sample is a reflection of the characteristics of the certain group ( population) as a whole. Sample size is the number of representative samples (individual pieces of data) used to calculate a set of statistics. The greater this number the better the determination of the average values of their data. Having greater number of samples also avoids errors from testing a small number of possibly atypical samples.

<h2>Answer with Explanation </h2>

Representative Samples are expected to reflect qualities or let's examine a bit of the key reasons why scientists use this every person from a people. The greater the precedent is, the more likely it will absolutely reflect what exists in the people. The individual coincidentally, used a system ordinary to mathematicians and analysts called Sampling. Specialists use reviewing to get a measure of things they can do with critical exertion count. Scientists screen the change (addition or decrease) of masses numbers to settle on decisions about issues that impact people.

Pani-rosa [81]

Answer: c) Some organisms rely on energy captured from inorganic compounds to drive basic biological processes.

Explanation:

Deep-sea hydrothermal vents are hot spots of geothermal water. The organisms living in deep-sea vents cannot obtain energy from sunlight. They are dependent on chemosynthesis, which involves the utilization of inorganic substances to produce organic substances, which allows their survival and act as a source of energy. In the given situation, bacteria present on the surface of mussels are capable of chemosynthesis also the mussels are dependent upon inorganic hydrogen in seawater. Thus chemosynthesis supports the survival of organisms living in the deep sea vents.
