Evolutionary Theories: Neutral, Punctuated Equilibrium & Population Genetics
Evolutionary Theories and Population Genetics
Genetic recombination during meiosis results in offspring variations. These variations occur randomly and are pre-adaptive.
Hardy-Weinberg Principle
Hardy and Weinberg demonstrated that in a population (k) + tax, individuals die and lose characteristics, but the population remains. The genetic stocks are all individuals with the ability to reproduce sexually with each other.
Evolutionary Forces
Fisher, Haldane, and Wright demonstrated that changes in gene

Proof of December: System Open
As it relates to the environment, there are constant exchanges.
Context
Organizations are open systems that relate to the context and are heavily influenced by it. The context is made up of all those factors that are outside the organization and affect its development.
General Environment
Composed of all those factors that influence the general social environment in which organizations develop their activities. Examples: Cultural factors, technological, educational.

Topic 6: Prototyping
The objective of prototyping is to test the design concept, the service design, and their underlying new proposed ideas and solutions to approve or reject them. If they are approved, the process goes ahead. If they are not approved, then they should be amended, improved, and fine-tuned depending on the results of the prototype testing. Their ideas should be revised, etc.
What is Service Prototyping? Prototyping Goals
It is a lightweight simulation or sample version of the actual

Mausoleum of Theodoric: Architecture, History, and Interpretation
Mausoleum of Theodoric: A Historical Overview
The Mausoleum of Theodoric stands as a testament to the Ostrogothic presence in Ravenna. Unlike other Germanic Ostrogoths, Theodoric embraced the existing culture of Ravenna. The mausoleum’s most striking feature is its roof, the largest monolith used as a cupola in history. This massive structure has a diameter of 10.73 meters at its base, is approximately 1 meter thick, and weighs 300 tons.
The roof features a series of anchors, brackets, or rings inscribed

Plato’s Theory of Ideas
The theory of the ideas of Plato is the backbone of his philosophy and a highly influential concept. According to this theory, there are intangible, ideal forms existing in an objective and absolute realm, separate from the physical world. Within a hierarchy of ideas, the idea of good illuminates all other ideas. Lower in the hierarchy are ideas of beauty, justice, and unity, followed by ideas of polar elements and mathematical entities, and finally, ideas of material beings

Key Political and Economic Ideologies Explained
Here’s a breakdown of important political and economic ideologies:
History
History is the science that aims to study the past of humanity itself and serves as a method of social science. Contemporary Age is the historical period between the French Revolution and the present (1789 to present).
Geographic Area
A geographic area is a social product, a synthesis of the action of human groups on their environment for their necessary maintenance and reproduction

Understanding Runoff, Rivers, and Water Systems
- Runoff: The displacement of water across the Earth’s surface.
- River: A continuous stream flowing into other rivers, lakes, or the ocean.
- Channel: The path through which a river flows.
- Flow: The amount of water a river carries, measured in cubic meters per second (m3/s). This is influenced by climate, relief, lithology, vegetation, and human activity. Channel stabilization is important for accurate measurement.
- Absolute Flow: The amount of water flowing past a specific point in the river per second.
- Catchment
Cell Biology: Structure, Function, Metabolism, and Photosynthesis
Cells (Chapter 4)
- Cell Theory: 3 Main Points
- All organisms are composed of cells.
- Cells are the smallest living things.
- Cells arise only from pre-existing cells.
- Cell Size vs. Volume Ratio
- An organism made of many small cells has an advantage over an organism composed of fewer, larger cells.
- As a cell’s size increases, its volume increases much more rapidly than its surface area.
- Microscopes: Functions and Types
- Light Microscopes
- Use magnifying lenses with visible light.
- Resolve structures that are 200 nm
