You find a sedimentary rock that contains pieces of igneous rock. what is the best explanation for how pieces of igneous rock got there?

There are dozens

Explosive materials such as pumices, lapilli and ashes may be blown by volcanoes thousands of kilometers around and fall in a sedimentary basin.
Erratic are all sorts or rocks transported by glaciers and abandoned wherever the lower altitude will stop their front. Rivers also transport materials from one basin to another. So does the wind.
Rocks of continental origin, such as sandstones, conglomerates etc. are all sedimentary rocks and may well contain igneous fragments.

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
