Zander is conducting an investigation, and he used this video. Which statement best describes what Zander is testing in his experiment? When a substance changes from a gas into a liquid due to a change in temperature, melting occurs, which is a physical change.

When a substance changes from a solid into a liquid due to an increase in temperature, it is a physical change.

When a substance changes from a gas into a liquid due to a decrease in temperature, the substance cools down and condenses, which is a phase change.

When a substance changes from a liquid into a gas due to a decrease in temperature, the substance evaporates and cools down, which is a phase change.

Explanation:

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

i do not know and i have a 100 in this class
