<span>You need to be able to at least enough to have a unique code at each position. For example, 3 bases is enough for us because that is the minimum that gives a unique code for each. If there was only 2 bases, you would have only 16 unique combinations.
You need to calculate the number of combinations for each length (which is # of base choices (2) to the x power, where x equals the number of positions).
1 position= 2^1 = 2
2 positions = 2^2 = 4
3 positions = 2^3 = 8
4 positions = 2^4 = 16
5 positions = 2^5 = 32
5 positions is the first that gives at least 17 unique codes so the minimum size of the martian codon is 5 bases.</span>
There are 2 fundamental theoretical approaches detailing the origin of the cell: purely naturalistic, and theistic. The naturalistic approach involves a number of possible theories, the goal being to find the simplest combination of critical functional elements that could be called a living entity and not requiring a cell membrane, rather some form of metabolically and reproductively viable configuration that could be called the first lifeform. This is considered marginally viable as the cell membrane is essential for holding the cell together, protecting the interior, and allowing the outflow and influx of chemicals necessary for cellular function. A more challenging and less substantiated theoretical approach with a number of theories calls for all atoms of the chemical elements needed for the construction, operation, and reproduction of the first cell overtime collect and interact at increasingly higher levels of complexity until a complete cellular entity results. Neither answers the question how the non-living material collected actually comes alive.
The theistic approach proposes that God designed the total requirements for the first cellular life then set the conditions for its elemental collection, biochemical assembly and ultimate transition to a living entity.The viability of this approach is high considering the problems it solves:
1. The non-existence of any natural processes or forces to accomplish the total cellular assembly or transition to living status.
2. The absence of any combination of conditions that could colocate, coincide, concentrate, and mitigate contamination of required elements.
3. Resolve the creation and assembly of homochiral amino acids with homopolymer sugar backplanes.
4. Create and code the DNA, RNA and proteins required for cellular operation and reproduction. DNA and RNA are made of proteins but DNA is required to produce proteins.
5. Create and assembly the cell membrane that accomplishes all the required functions.
6. The accomplishment of all the above under environmentally stressful conditions of the primordial Earth.
Much more could be added.
Answer:
Independent variable: exercise
Dependent variable: grades
Constants: same kind of exercise, same set of students
Yes, there is a control group. The control group are the 10 people that do not exercise
Explanation:
In an experiment, the independent variable is that variable that the experimenter changes or manipulates. In this case, the independent variable is the EXERCISE.
The dependent variable is the variable that responds to changes made to the independent variable or the variable that the experimenter measures. In this case, the dependent variable is the GRADE of the people.
The constant is the variable that the experimenter must keep constant or unchanged throughout the experiment. In this experiment, the constants are the same kind of exercise, same set of people used.
In this experiment, there is a CONTROL GROUP. The control group is the group that does not receive the experimental treatment in the experiment. In this case, The control group are the 10 people that do not exercise
