Sorting living things into groups.
Classification
Cells are the basic building blocks of all living organisms
Smallest structural and functional unit
Cells
change in variation over time; process by which modern organisms have descended from ancient organisms
Evolution
diaphragm, lungs, trachea, mouth, nose these are examples of what system.
respiratory system
What is a Biotic factor
Living things in a ecosystem
The largest groups that living things are sorted into.
kingdom
That single cell performs all the functions that the organism needs to survive
Unicellular
What is when animal inherited characteristic that increases a chance of survival
adaptation
esophagus, stomach, small intestine, colon these are examples of what system?
digestive system
This is Any living thing
Organisms
Differences between organisms that are due to the environment.
Environmental Variation
Controls what substances come in and out of the cell.
Cell Membrane
Organisms with more advantageous traits for their environment survive and reproduce more often
Natural selection
heart, veins, arteries, capillaries these are examples of what body system
circulatory system
What do u call when a close relationship; one species benefits, the other is harmed
Parasitism
A group of organisms that can reproduce with each other to produce viable offspring.
Species
They convert energy in food molecules
Mitochondria
What is when a mother spider lays about 100 eggs.
Overproduction
This body system produces hormones that help regulate some of the body's activities
Endocrine System
What is a close relationship; both species benefit
Mutualism
Differences between organisms that are due to their parents.
Inherited Variation
What is a Multicellular cell
Multicellular organisms are made of many cells and have specialized shapes that allow them to perform specific functions
the differences within a single species
variation
This body systems keeps infectious microorganisms out of the body, and to destroy any infectious microorganisms that do invade the body
Lymphatic/Immune System
What is a series of steps in which organisms transfer energy by eating and being eaten User
Food Chain
