Answer:
-provides protection for a cell
-provides a fixed environment inside the cell.
-The cell membrane also provides some structural support for a cell.
Explanation:
Answer:
585ml
Explanation:
13 fold means that volume of the diluted solution is 13 times higher than the volume of the stock.
It means you have to perform 1:13 dilution
D f = Vdiluted/ Vstock
Vdiluted = 13 × Vstock
Vdiluted = 13 × 45ml
Vdiluted = 585ml
You will need to add enough water to the stock (MgSO4) solution till it gets to a total volume of 585ml
Answer:
Solid: State of matter with definite shape.
Gas: State of matter with particles very far apart.
1 or 3: Arrows that show particles getting closer together.
2 or 4: Arrows that show particles gaining energy.
Gas: State of matter that will fill any container.
Liquid: Sate of matter with definite volume but not shape.
Solid: State of mater with least amount of kinetic energy.
Explanation:
There are three states of matter :
Solid: It is the state in which atoms are tightly packed such that either they can make no movement at all or just can cause vibrations. Hence, solids have a definite shape and volume.
Liquids: When the solid molecules are heated, they gain energy and free themselves, converting into the liquid state. The molecules have a definite volume but not a definite shape.
Gas: When liquid molecules are heated together, they gain more energy and start hitting the walls of the container with a much greater space. They move more freely in this state and hence the molecules do not have a definite shape or volume in this state.
