Which statements describe the cyclic nature of seafloor spreading? check all that apply. continents are created. new oceanic crust is created. volcanoes erupt and produce more crust. old crust is destroyed at subduction zones. old crust is pushed away from oceanic ridges.

New oceanic crust is created.Old crust is destroyed at subduction zones.Old crust is pushed away from oceanic ridges.

Explanation;Seafloor spreading is a geologic process in which tectonic plates split apart from each other producing new seafloor.The process of seafloor spreading results from the mantle convection which is the slow, churning motion of the mantle. It occurs at divergent plate boundaries. Seafloor spreading occurs along mid-ocean ridges, and old crust is pushed away from the oceanic ridges. Oceanic crusts move slowly from oceanic ridges and sites of seafloor spreading making them cooler, more dense and thick.

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
