|---|
| Invertebrate | Animal with no backbone |
| Budding | Form of Asexual Reproduction |
| Species | Group of organisms that can mate with each other and produce offspring who can then mate and reproduce |
| Regeneration | The ability to re-grow a body part |
| Ovaries | Where eggs are formed in humans |
| Gills and Lungs | Enable oxygen to get into an animal's blood |
| Mouth | Place where an enzyme is added to food, the teeth break food into smaller pieces, and both mechanical and chemical digestion begins |
| Small Intestine | Place where all digestion is completed in humans; contains small villi that absorb nutrients |
| Kidney | Organ that filters the blood and removes wastes (urea) |
| Human Heart | Contains 4 chambers |
| Capillaries | Small thin walled blood vessels that connect the arteries to the veins |
| Red Blood Cell | Part of the blood that contains hemoglobin and carries oxygen |
| Peristalsis | Process by which food is able to pass through the esophagus to the stomach |
| Alveoli | Place in the lungs where gas exchange occurs; small component of the respiratory system |
| Skin | Cools the body, Removes wastes such as urea and salt, provides water proof protective layer |
| Asexual Reproduction | Regeneration of a sea star, budding of a hydra, bacteria cell splitting into two smaller bacteria are all examples of this type of reproduction |
| Hypothesis | Statement tested during a scientific experiment (educated guess) |
| Graduated Cylinder | Used to measure volume |
| Homeostasis | An organism's ability to maintain stable condition |
| Cell | Basic unit of structure and function in an organism |
| Circulatory System | Body system that transports hormones and nutrients |
| Uterus | Where the fetus develops for nine months in humans |
| When food is digest completely, it can | Easily pass through the cell membrane |
| Respiratory System | Body system responsible for the exchange of gases (oxygen and carbon dioxide) between the external environment and the body's cells |
| Sexual Reproduction | Reproduction that leads to the possibility of variations in the next generation |
| 23 | Number of chromosomes in an egg or sperm cell |
| Digestive System Organs | Stomach, small intestines, large intestines |
| DNA | Located in the nucleus of a cell, associated with the process of Reproduction; shaped like a twisted ladder or double helix |
| Flowers | Place where sexual reproduction occurs in plants |
| Parasite | An organism that lives inside of a host |
| Presence of a Backbone | One characteristic scientists use to classify animal |
| Virus | Non-living, does not contain organelles, Must invade other cells in order to reproduce |
| Paramecium | Surrounded by hair-like cilia that enable them to MOVE |
| Heredity | Passage of traits from one generation to another |
| Chloroplasts | Where a plant captures the light from the sun |
| Genes | Passed on from parent to child |
| Recessive Trait | In order to receive a recessive trait, both parents must CARRY this TRAIT |
| Extinction | Caused by natural catastrophes, climate change, introduction of a foreign species |
| Mitosis | New cells have an exact copy of the parent cell's genetic material |
| Living Things | Have cells |
| All Plants and Animals | Have Mechanisms that transport nutrients and water |
| Nervous System | Body system that involves the interaction of the skeletal and muscular systems to produce locomotion |
| Microorganisms | Can cause infections |
| Compete for Food | Different Species of carnivore animals that share the same habitat in an ecosystem may do this |
| Existing Cells | All cells come from |
| Autotroph | Can make its own food using raw materials and the sun's energy |
| Regulation | Controls the amount of sugar found in the blood |
| Energy | All organisms must have a source of this to survive |
| Selective Breeding | Mating Smaller dogs from each litter for several generations to produce a smaller variety of dog is an example of this |
| Chromosomes | Carry genes composed of DNA molecules |
| Fruit | Ripened Ovary |
| Evolution | Changes in a species that occur over a long period of time |
| Adaptations | Traits that help an organism to survive and reproduce in its environment |
| Gregor Mendel | Studied Chia seeds; developed many rules that govern the passage of traits from one generation to the next |
| Charles Darwin | Developed the Theory of Natural Selection |
| Diffusion | Movement of molecules from an area of high concentration to low concentration |
| Photosynthesis | Process plants use to make their own food |
| Cellular Respiration | The lungs absorb oxygen when a person breathes to carry out this process |
| Circulatory System | Responsible for delivering more oxygen to the cells |
| Genetics | The study of heredity |
| Osmosis | Movement of water from a high concentration to a low concentration through the cell membrane |
