Soils are home for a wide variety of organisms such as worms and other tiny animals such as insects, arthropods (like spiders and millipedes). there are also organisms such as fungi and bacteria. collectively these organisms serve two very important services to/in the soil. what are these services?

The organisms break down and decompose dead material that are found in the soil. Therefore they provide nutrients that benefit trees and plants. Organisms like the worms and millipedes turn the soil as the move through it. This ensures that the soil is well ventilated with enough air to be used by plants.

q: compare the parts of a cell and the cell as a whole to another common nonliving system (i.e., a car, a city,

a:

comparing this to the inside of a food building/company.

plasma membrane - building's walls

all cells are surrounded by a plasma membrane, which protects the cell from its environment, keeping toxic substances out of the cell. it regulates which molecules are allowed to enter and exit the cell.

nucleus - the big boss

regulates all cell activity such as cellular metabolism, and growth in addition to storing and maintaining the cell's dna for transcription and replication. determines what proteins to make.

cytoplasm - working areas

contains the organelles; site of most cell activity

endoplasmic reticulum - engineer's work area

the place where ribosomes do their working activity.

ribosomes - engineers

builds the proteins.

golgi apparatus - pickup truck drivers

prepares proteins for use or export.

lysosomes -   investigators

responsible for breaking down and absorbing materials taken in by the cell.

cytoskeleton - renovators

maintains cell shape.

mitochondria/chloroplasts - materials scientist

transforms one form of energy into another.

The correct answer is c
