They cannot move freely but they can vibrate

Answer from: AestheticRoses

A liquid has a definite volume (which can change with temperature), but takes the shape of its container.

A Liquid is the state that has no definite shape, since the atoms can move around, it is therefore able to form itself to the shape of its container. However, since the atoms still have weak bonds to one another, it cannot fill up a closed container by stretching out the atoms. (The form of matter that does this is a gas.)

* Liquids can be very slightly compressed, but not to the extent of gases.

There are 3 phases of matter. Solids, liquids and gases. Solids have a definite shape and a definite volume. Liquids do not have a definite shape but do have a definite volume. Gases do not have a definite shape as they can "flow", and they do not have a definite volume as they can fill a container by changing in pressure (density).

im gonna compare the cells to jobs in factory. give brainliest

job in the factory // cell organelle //

shipping/receiving

department plasma membrane

chief executive officer// nucleus

factory floor // cytoplasm

assembly line// endoplasmic reticulum

workers in the assembly line //ribosomes

finishing/packaging department //golgi apparatus

maintenance crew //lysosomes

support beams (walls, ceilings, floors) //cytoskeleton

power plant //mitochondria/chloroplasts

here's what each part of the cell does:

plasma membrane :

regulates what enters and leaves the cell; where cell makes contact with the external environment

nucleus :

controls all cell activity; determines what proteins will be made

cytoplasm :

contains the organelles; site of most cell activity

endoplasmic reticulum:

where ribosomes do their work

ribosomes :

build the proteins

golgi apparatus :

prepares proteins for use or export

lysosomes :

responsible for breaking down and absorbing materials taken in by the cell

cytoskeleton :

maintains cell shape

mitochondria/chloroplasts :

transforms one form of energy into another

Seen in some gram-positive bacilli, occurs when only the inner portion of a cell wall is deposited across the dividing cell. this new cross wall puts tension on the outer layer of the old cell wall. eventually, the outer wall breaks at its weakest point with a snapping movement that tears it most of the way around. the daughter cells can then remain hanging together almost side by side being held by a small remnant of the original outer wall. choose from the following statements the ones that correctly discuss reproduction using binary fission in a bacterial cell. select all that apply. view available hint(s) select all that apply. due to the stretching of the cytoplasmic membrane, both cells will contain a complete genome. each daughter cell will contain an equal number of organelles. the daughter cell will be a permanently smaller copy of the mother cell but will contain a complete genome. each daughter cell is an exact copy of the other, both genetically and morphologically
