A statistical hypothesis, sometimes called confirmatory data analysis, is a hypothesis that is testable on the basis of observing a process that is modeled via a set of random variables.
Answer:
Explanation:
Classification of organisms is done while considering many factors such as:
Cell type- whether the organism is prokaryotic or eukaryotic
Cell structure- This includes both the presence and composition of the cell wall
Body type- whether the organism is multicellular or unicellular
Mode of nutrition- the method through which the organism achieves its nutritional requirement, by consuming other organisms (heterotroph) or making its own food (autotroph)
Throughout our lives all of our bodily systems have cells that duplicate themselves. After a certain number of years, these cells begin to start dying off, or become more prone to mutations that occur in the cell replication process. An example is the eventual death of muscle cells that lead to reduced muscle tone and strength in the elderly. Concerning mutations in cell replication, the more times something happens the more chances there are that something can go wrong. If a cell has replicated itself twenty times, there has been little opportunity for something to go wrong, but when cells have replicated hundreds or thousands of times, pure odds mean the chances are greater for "mistakes". These mutations are what leads to certain diseases that are more greatly associated with aging, such as certain cancers.
Protein act as buffers. Buffers are resistant to pH changes. So when too much acidic components are present in the blood, proteins bind to them so that it does not change the net pH of the blood. Example of this is the hemoglobin or the red blood cells.
