There's this boy in my class named Jarris Henderson Brown and i really like him but i don't know if he likes me. So i asked santa to make it possible that me and him can go out but for some reason deep down in my heart i know it won't happen.

What are two different ways things are transported passively?
diffusion(movement of solute from area of greater concentration to lesser) osmosis(movement of water from an area of greater water concentration to lesser)
How is diffusion important to cell processes such as photosynthesis?
Diffusion is the process by which small particles move from a place of high concentration to a place of lower concentration. By diffusion, small molecules like salts can go inside a cell from the outside. To keep itself alive, a Cell needs to take in many things from its outside. In Photosynthesis, gaseous Carbon Dioxide (CO2) enters the plant cell by diffusion. CO2 is very important in building food and making energy for the plants.
What is superstitious?
Superstitious is believing in things that are very untrue. Simple as that.
When enough experimental data support a hypothesis becomes a(an)?
The hypothesis can never really be proven correct; that's why scientists always say that they are 99.9% sure about things. If you drop a pencil, it will most likely always fall, but there is the slight chance that someday, it won't fall. Things in science always change.
What 3 things do you always bring to science calss?
you bring paper and pencil and a backpack
What impact does osmosis and diffusion have on life?
If osmosis and diffusion didn't exist then cells In things would be dry and shrink
Where do diffusion and osmosis occur in livings things?
In cells
What are two ways of moving things into and out of cells that do not need?
Diffusion and Osmosis
What are the two ways of moving things into and out of the cells that do not need energy?
osmosis and diffusion
What are two ways of moving things into and out of cells that do not need energy?
Diffusion and Osmosis
What cause certain things to enter cell?
Things can enter the cell through various processes, such as osmosis, diffusion and active transport. Passive transport (diffusion/osmosis) occurs because of a difference in concentration across the membrane.
Two ways of moving things into and out of cells that do not need energy are?
Without a doubt it is diffusion and osmosis....
Which process of living things produces water that enters the water cycle?
Osmosis. Osmosis is the diffusion of WATER specifically. sources: 8th grade living environment (9th grade science)
Osmosis does it need energy?
No, actually diffusion is a kind of passive transport, and osmosis is a kind of diffusion. Any passive transport can happen without energy (contrary to active transport). Since, all the things you listed were passive transport, they happen down the concentration gradient and need no ATP.
What is the process in which molecules move in and out of cell?
The movement of things through the cell would be called diffusion. If it is water we are talking about then it is called osmosis. diffusion and osmosis are examples of inactive transport. Active transport involves specific proteins in the cell that pull material in the cell though the cell membrane.
What two things make osmosis a special type of diffusions?
Osmosis is specifically the diffusion of water, so that's one thing which makes it special. The other is the fact that it occurs through a semi-permeable membrane.
What are two ways of moving things in and out of a cell that do not need energy?
transpiration and diffusion through cell walls.Tranpiration is only for plant cells and animals cells do not have a cell wall. For animal cells there is diffusion and omosis through cell membranes.diffusion, osmosis, and facilitated diffusion
