True or false: Radiation is a type of heat
transferred through empty
space.

True

Explanation:

Energy can "move" in various ways:

- Conduction

- Convection

- Radiation

Radiation relies on propagation of Electromagnetic Radiation; basically waves, such as light, x-rays, u-v or infrared, are electromagnetic waves that transport energy.

These waves can travel through vacuum because they do not need a material medium (as in sound waves) to propagate but are a perturbation of the electromagnetic field.

Each wave will carry energy in the form of...packets called Photons (kind of a rain of "droplets" of light!!!).

true

Explanation:

Radiation is the transfer of heat energy through space by electromagnetic radiation.

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
