The design of an experiment is synergistically related to the method of difference. Both are required in order to test a hypothesis and deliver a conclusion or evidence.
What is an Experimental design?An experimental design may be defined as the procedure of accomplishing research in an objective and regulated fashion so that accuracy is maximized and specific conclusions can be haggard regarding a hypothetic statement.
An experimental method may be defined as a methodology that is significantly executed in order to draw evidence or conclusion based on the hypothesis.
Both experimental plan and experimental method are required in order to withdraw specific conclusions about an experiment. In the absence of either factor, it is tough to deliver scientific evidence.
Therefore, the design of an experiment is synergistically related to the method of difference. Both are required in order to test a hypothesis and deliver a conclusion or evidence.

Paramecia that live in freshwater have contractile vacuoles, while those that live in salt water do not. Why do you think this is the case?
Answer:
water enters by osmosis, vacuole is used to pump out excess water.
Explanation:
Paramecia that live in freshwater would have contractile vacuole because they will need to get rid of excess water unlike those that live in salt water.
The vacuole primarily functions to get rid of excess water from the cell.
Freshwater is hypotonic to the cytosol of paramecia. Thus, water will always enter the paramecia cells by osmosis. If the excess water is not excreted from the cell, turgidity will result and the cell may burst.
On the other hand, salt water is likely hypertonic to paramecia cells. Thus, instead of having vacuoles for water excretion, a mechanism would have to be put in place so as not to lose too much water to the surrounding salt solution. In other words, a vacuole would be totally redundant in the hypertonic solution.

Answer: creationists believe in higher power to create things as is and evolutionists believe we originate from a common past and constantly change
Explanation: Creationists believe the belief that the universe and living organisms originate from specific acts of divine creation, as in the biblical account, rather than by natural processes such as evolution.
The theory of evolution is based on the idea that all species are related and gradually change over time. Evolution relies on there being genetic variation in a population which affects the physical characteristics (phenotype) of an organism.
Answer:
Creationists believe that natural selection is a God ordained process. Evolutionists believe that natural selection is a scientific process.

What happens to prey populations when predators eat some individuals
Answer: They grow more slowly, reproduce less, and populations decline. ... As predator populations increase, they put greater strain on the prey populations and act as a top-down control, pushing them toward a state of decline. Thus both availability of resources and predation pressure affect the size of prey populations.

Next Sandra tests the hardness of each mineral by scratching it with different materials as shown in the chart. The values in the chart are based on the Mohs Scale of hardness, which ranks the hardness of minerals on a scale of 1 to 10. The harder the mineral is, the higher its rating will be. If the material is harder than the mineral, it will scratch the mineral. For example, according to this scale, if a mineral is unable to be scratched by a steel nail, then the mineral has a hardness greater than 6.5.
