Closed and Open Systems An open system is one that receives input from
outside the system. For example, your body is an
open system because it receives food and oxygen
from outside the system (your body). What is another
example of an open system?

A rock in a field

An earthworm taking in soil for nutrition

earthworm taking soil for nutrition

Explanation:

it's consuming the energy unlike the rock

lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). the enzymes responsible for this hydrolysis require an acidic environment for optimal activity. hope i !

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
