Answer:
The sample mean is obviously different from the population mean, but tests of significance must be done to determine if the difference is statistically significant. The difference could possibly be attributed to chance or to sampling error.

Answer:
The scientific study of life, called <u>Biology</u><u>, </u>can be organized around several themes. As the biological hierachy builds from molecules on up to ecosystems, each level has <u> emergent properties</u> that result from interactions among component parts. Life's basic unit of <u>structure and function</u> is the cell, which occurs in two basic forms- prokaryotic and eukaryotic . As organisms interact with the environment, <u>nutrients and chemicals</u><u> </u>cycle within an ecosystem, while energy flows one way from sunlight -> chemical energy -> heat. According to the core theme of <u>evolution </u>all of life is related by common descent. Life was diversified as <u>natural selection</u> had led to the gradual accumulation of adaptations that fit populations to the environment.
Explanation:
Emergent properties- Properties that is exhibited by a group of individuals as a result of interaction among them.
Evolution- the process by which populations develop new characteristic and become more efficient than their ancestors.
Natural selection- A phenomena in which only fittest organisms of a population are allowed to survive in a given environment. This play a key role in evolution.
If the mass of object increases, the weight will stay the same. The weight is a factor which is dependent on gravity, while mass is a constant.
Answer:Self-assembly into a simple membrane
Explanation:
The cell membrane is the biological membrane that separates the interior of the cell to the exterior of the cell.
The cell membrane is made of lipid by-layer. The first cell membrane was made of lipids. It is so because it has the ability to assemble and form a membrane like structure.
It helps in entry and exit of the substances from inside of the cell to outside and vice versa.
