What happens to a cell when it is placed in salt water?
A cell place in salty solution would loose water as water will move from cell to surrounding hypertonic medium by the process of osmosis causing the cell to shrivel up.
Can Salt move through cell membrane?
How are they able to do so? Sodium ions pass through specific channels in the hydrophobic barrier formed by membrane proteins. This means of crossing the membrane is called facilitated diffusion, because the diffusion across the membrane is facilitated by the channel.
In what two ways does water move across the cell membrane?
Water moves across cell membranes by diffusion, in a process known as osmosis.
In which direction will SALT move explain your answer?
Water will move in the direction where there is a high concentration of solute (and hence a lower concentration of water. Salt is a solute, when it is concentrated inside or outside the cell, it will draw the water in its direction.
What is diffusion explain with an example?
Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. For instance, a gas diffuses very quickly in another gas. An example of this is the way the noxious smell of ammonia gas spreads in air….
What is an example of stimulus diffusion?
Stimulus diffusion is when an idea spreads to another culture or region and is then altered or changed in order to adapt to that culture. An example of this would be Chinese porcelain, which was wildly popular in Europe but extremely difficult to transport over such long distances.
What are the four types of diffusion?
each group a different type of diffusion (relocation, hierarchical, contagious, or stimulus). Each group should come up with one example of diffusion for each of the four different types of scale: local, regional, and global.
What are the 5 types of diffusion?
Relocation, expansion, contagious, hierarchical, and stimulus diffusion.
How does diffusion play a role in globalization?
SOCIAL. Economics played a big role in globalization and cultural diffusion. For example, many trade agreements and trade blocs determined trading rights for different countries. Also, cultural diffusion led to new products being imported and introduced to new areas.
How does diffusion change culture?
Besides local invention, cultures can also change through cultural diffusion. Cultural diffusion is the spread of ideas, beliefs, and goods from one place to another. When people from one culture interact with people from another, aspects of culture tend to spread from one place to another.
Which of these is the imposition of one culture on other cultures?
What are 3 ways that culture changes?

What are examples of cultural change?
The following are illustrative examples of culture change.
- Invention. Technological change has a broad impact on culture.
- Economy. Economic systems and conditions.
- Globalization. The process of exchange and integration that occurs between nations.
- War & Disaster.
- Rights & Freedoms.
What is cultural change and its effect?
Moreover, new things are added to material culture every day, and they affect nonmaterial culture as well. Cultures change when something new (say, railroads or smartphones) opens up new ways of living and when new ideas enter a culture (say, as a result of travel or globalization).
What factors make up culture?
The major elements of culture are symbols, language, norms, values, and artifacts. Language makes effective social interaction possible and influences how people conceive of concepts and objects.
