1). Mutations supply new traits.
2). Organisms produce more offspring than can survive.
3). Selection allows only those with the best traits to survive.
For a theory to be considered proven, it typically must pass three key tests: empirical validation, consistency, and predictive power. Empirical validation requires the theory to be supported by observable and repeatable evidence. Consistency means the theory should align with existing knowledge and not contradict established laws of science. Lastly, predictive power indicates that the theory can accurately forecast future events or outcomes based on its principles.
A well tested explanation of a wide range of observations is known as a Theory, such as the Theory of Gravity or the Theory of Evolution.

A summary typically includes three main parts: the main idea or thesis statement, key points or arguments that support the main idea, and a conclusion that encapsulates the overall message. The main idea provides the central theme of the text, while the key points highlight essential details or arguments. The conclusion synthesizes the information and reinforces the significance of the summary. Together, these components create a concise representation of the original content.
The periodic table of the elements forms the basis of chemistry, the prevailing theory is that each element is primarily distinguished from another by the number of protons in its atomic nucleus. The primary theory of cosmology is the "big bang" theory. This is not a particularly good name, because it evokes the idea of an explosion, which is not really how it occurred. Astronomy consists of both the big bang and Subrahamanyan Chandrasekhar's theory of stellar evolution. The primary theory of geology is plate tectonics. For biology the key concept is Charles Darwin's theory of evolution. Isaac Newton's method of fluxions (theory of calculus) is probably the key concept in mathematics, much as Euclid's Elements form the basis of geometry.
The three main key points of an article are author, subject, and conclusion.
nobody cares but I cares
A shot taken from the top of the key in basketball is worth two points if it's taken inside the three-point line. If the shot is taken from beyond the three-point line, it is worth three points. The value of the shot depends on the player's position relative to the three-point arc.
Research suggests that audiences can generally remember around three to seven key points during a presentation or speech. The "magic number seven, plus or minus two" theory, proposed by psychologist George A. Miller, indicates that our short-term memory can effectively retain this range of information. To enhance retention, it's important to present these key points clearly and reinforce them through repetition or visual aids.
Outside of the "key", but in the same half of the court, there is another line, roughly in the shape of a half circle. Shots made from outside of this line are awarded 3 points. They are sometimes referred to as "field goals".
Paragraph 2 expands on the main idea introduced in the introduction by providing three key points that further support the initial concept. These points serve to explain and elaborate on the topic introduced in the introduction, adding depth and details to the overall discussion.
A unique plane is defined by three non-collinear points. This means that the points must not all lie on the same straight line. If the three points are collinear or if only two points are given, they do not suffice to define a unique plane. Thus, the key restriction is that the three points must be non-collinear.
The three conclusion components are1. Restate the topic.2.Summarize key points in your paper3. Leave them thinking
It is said that every great message contains at least one key point but not more than three.
The key of A major with three sharps (F, C, G) is significant in music theory because it is a common key used in classical and contemporary music. It has a bright and uplifting sound, making it popular for compositions that convey a sense of joy or celebration. Additionally, the presence of three sharps in the key signature indicates that certain notes in the scale are raised by a half step, creating a unique harmonic and melodic structure.
The key points of the germ theory of disease are that microorganisms (germs) are responsible for causing infectious diseases, these microorganisms can be spread from person to person, and that proper hygiene and sanitation practices can prevent the spread of these diseases.
There are three parts of a restatement sentence. These parts include restating the topic, summarizing the key points, and leaving the audience thinking.
