What is Pierre Molchanov or Molchanoy famous for?
Pierre Molchanov, also known as Pyotr Molchanov, was a Russian mathematician known for his work in probability theory and stochastic calculus. He made significant contributions to the study of diffusions and stochastic processes. He is also known for the Girsanov transformation and the Molchanov-Taylor formula.
Explain why diffusion is evidence for particle models?
Diffusion occurs because particles move randomly in all directions until they are evenly distributed. This can be explained by the particle model, which states that matter is made up of tiny particles that are constantly in motion. The movement of particles in diffusion supports the idea that substances are composed of particles that are constantly moving.
Why is historical globalization an important issue?
Historical globalization is important because it has significantly shaped our world today by influencing the exchange of ideas, cultures, technologies, and goods among different societies. Understanding historical globalization helps us make sense of current global challenges and relationships, especially in terms of power dynamics, inequality, and cultural diffusions. It also sheds light on how past events have laid the groundwork for contemporary issues such as colonization, migration, and economic interdependence.
What are the similarities between diffusion and facilitated diffusion?
Diffusion is the main method by wich small molecules move across the cell membrane. while many cellular processes depend on osmosis because cells cannot function properly without adequate water. Facilitated diffusion works through channels and Osmosis only works with water.
What affects the rate of diffusions?
Temperature, Concentration and size of molecules :)
What are few examples of cultural diffusions?
Does anyone know what an educational facility is???
What are the types of diffusions?
In Biology there are three types of diffusion. There are simple, channel, and facilitated diffusion.
What are diffusions of particles through protein channels called?
Diffusion of particles through protein channels is called facilitated diffusion. This process allows specific molecules or ions to pass through the cell membrane with the help of transport proteins.
How the use of solidified jelly solution can improve the observation of the rusting experiment?
Solidified jelly solution can improve the observation of the experiment as it is used to trap and see the blue colouration clearly. This is because diffusions occurs the slowest in solids compared to liquid and gases.
What is the importance of cultural diffusions?
Civilizations, such as the Sumerians, exchanged products and ideas, such as living in cities, with neighboring cultures. This process in which a new idea or products spreads from one culture to another is called cultural diffusion. (McDougal Littell, World History: Patterns of Interactions, p.31)

Why is the alveolus suitable as a place for diffusion of gasses?
The alveolus is suitable for gas diffusion due to its large surface area and thin walls, which allow for efficient exchange of oxygen and carbon dioxide between the air in the lungs and the bloodstream. Additionally, alveoli are surrounded by a dense network of capillaries that facilitate rapid gas exchange.

How can the respiratory system put oxygen into the blood and carbon dioxide out of the blood?
Oxygen and carbon dioxide are both gases, which makes them easier to pass through the cell. In addition, the site of trading the respiratory gases occur at alveoli, which has capillaries attached to it. The membranes in these regions are each one cell thick, which enables the respiratory gases to pass through easier. When the blood reaches the lungs, simple diffusions then take the carbon dioxide out of the cell and oxygenates the blood.
Does salad dressing have anti freeze?
No - antifreeze is a specific chemical (ethylene glycol) used in car radiators to prevent the heat diffusions system from freezing in winter. However, you will notice that salad dressing doesn't freeze at 0 C (32 F) like water will. This is because salad dressing has oil (usually olive oil or another vegetable-based oil) and a number of solutes (seasonings, etc.) that disrupt the bonds between the water molecules. Because of this, salad dressing has to get much colder than water before it will freeze.
