Answer:
Percentage value is used for the predictions rather than the actual measurement this is so because the predictions can be wrong so the value is taken per 100 person or can be defined as per cent.
The actual measurements cannot be used because it is a prediction. Only the approximate value can be used so because there is no precise data.
There is no exact data which can be used to determine the predictions. So, prediction are always made in terms of per cent which means per 100.
Percentages are used in predictions to allow for easier comparison and understanding, especially when dealing with different sizes or categories. They offer a clear basis for approximation, which simplifies calculations, and are suited to the concept of prediction, which involves estimation rather than exact measurements.
We use percentages to make predictions rather than actual measurements due to the flexible and comparative nature of percentages. Percentages provide an easy comparison across different categories and sizes, as they proportionally represent parts of a 'whole' divided into 100 parts. This is particularly beneficial in inferential statistics where we rely on sample data to make generalizations about an unknown population.
For instance, in an election poll showing that a candidate has 40% of the vote with a margin of error of 3 percentage points, using percentages allows for easy comparison and understanding. If we used actual measurements, considering different total population sizes or the number of voters in different polls would make meaningful comparison more difficult.
Percentages also offer a clear basis for approximation, which can simplify calculations in many instances. Scientists often approximate the values of quantities to perform calculations and analyse systems, and percentages provide an accessible means to do this. Predictions, inherently, are not about exact measurements but estimations, so percentages are particularly suited to this task.

Any change in plant communities over time is called a(n) . 2. A common pioneer organism in a succession is the .
In biology, the term 'succession' is used to refer to the natural changes that occur in plant communities over time, often after a significant environmental disturbance. These changes happen in predictable order, beginning with 'pioneer species' (usually grasses and plants), followed by 'intermediate species' (smaller trees), and finally culminating into the 'climax community' where the forest resembles the pre-fire state.
Any change in plant communities over time is known as succession. This concept describes the sequential appearance and disappearance of species within a community. For instance, following a calamitous event such as a forest fire, the first plants to re-emerge are known as pioneer species which are essentially annual plants and grasses. As time progresses, environmental conditions change, and types of vegetation, such as small pine, oak, and hickory trees known as intermediate species appear. Ultimately, after a century or two, the forest will regain equilibrium and look the same as before the fire in a state known as the climax community. The process of attaining this stage in a community may also be triggered by short and long-term changes in the environment.

evidence of evolution
Answer: The breeder should choose the two dogs with those distinctive figures, thus concluding a mix of both breeds. This is evidence of evolution because a new breed will be brought up.
Explanation: Example, breeding a shih tzu and a poodle concludes to a new breed which is a p tzu. Sounds funny, but true. Evolving the dogs world even further.
Answer:
Cell membranes control the substances that enter or leave cells.
Explanation:
Without a cell membrane the organism will be unprotected and the homeostasis will die.
