DNA, which is a sequence of nucleotides, make up genes. Genes are DNA sequences that code of a functional protein and are controlled by a promoter region on the DNA. DNA, including genes within it, are supercoiled into chromosomes so they are able to fit in the cell. Otherwise, uncoiled DNA in a cell is much longer than the cell itself.
37. Observation and scientific theory are both related. Because it needs hypothesis and experiment to be able to have an actual data to show.
For example:
If you want to know how a monggo seeds grow on a wet cotton. Then you should be preparing the needed things and perform the experiment. You need to observe to be able to get the scientific theory of how this experiment works. That’s how observation and scientific theory is related. They will always be together in science.
Answer: Mitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself. In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes.
The great majority of the cell divisions that happen in your body involve mitosis. During development and growth, mitosis populates an organism’s body with cells, and throughout an organism’s life, it replaces old, worn-out cells with new ones. For single-celled eukaryotes like yeast, mitotic divisions are actually a form of reproduction, adding new individuals to the population.
In all of these cases, the “goal” of mitosis is to make sure that each daughter cell gets a perfect, full set of chromosomes. Cells with too few or too many chromosomes usually don’t function well: they may not survive, or they may even cause cancer. So, when cells undergo mitosis, they don’t just divide their DNA at random and toss it into piles for the two daughter cells. Instead, they split up their duplicated chromosomes in a carefully organized series of steps.
The act of reproducing the behavior of a process using a model that describes each step of the process is called simulation.
<h3>
What is simulation?</h3>
- A simulation is an ongoing replica of how a system or process might work in the actual world.
- Models must be used in simulations.
- The model reflects the essential traits or behaviors of the chosen system or process, whilst the simulation depicts the model's development over time.
- A computer simulation of an industrial process is an imitation of how one system or process operates through the operation of another.
- A simulation is a model or representative example of anything, according to the definition.
- A simulation is when you design a computer program with the goal of simulating piloting an aircraft.
- Simulation is fundamentally used to illuminate the underlying mechanics that govern a system's behavior.

False because if it’s burnt it would leave a trail of gas but it’s said 2 tails not 1 there was only one planet
