Biology Test 1
| Q/Blank | A/fill |
|---|---|
| ___, or thee study of life, offers an organized and scientific framework for posing and answering such questions about the natural world | Biology |
| ___ is the high degree of order within an organisms internal and external parts and in its interactions with the living world | Organization |
| A ___ is the smallest unit that can perform all of life's processes. Organisms made of one cell are ___, and organisms that are made of multiple cells are ___ | cell, unicellular, multicellular, |
| In the highest level, the organism is made up of organ systems, or groups of specialized parts that carry out a certain function in the organism. ___ are structures that carry out specialized jobs within an organ system. | Organs |
| ___ are groups of cells that have similar abilities that allow the organ to function. | Tissues |
| Organelles are tiny structures that carry out functions necessary for the cell to stay alive. Organelles contain ___, the chemical compounds that provide physical structure and that bring bout movement, energy use and other cellular functions. | Biological molocules |
| Another characteristic of life is that an organism can respond to a stimulus-- a physical or chemical change in the internal or external environment | (No Answer) |
| ___ is the maintenance of a stable level of internal conditions even though environmental conditions are constantly changing. | Homeostasis |
| ___ is the sum of all the chemical reactions that take in and transform energy and materials from the environment | Metabolism |
| The formation of two new cells from an already existing cells, as shown in the following photo is known as __ | Cell Division/Reproduction (asexual) |
| ___ is the process by an organism changes to be used or a specialized job | Development |
| All organisms produce new organisms like themselves in a process called reproduction. Reproduction, unlike other characteristics, is ___to the survival of an individual organism. | Not essential |
| Hereditary information is encoded in a large molecule called the deoxyribonucleic acid, or DNA. A short segment of DNA that contains the instructions for a single trait of an organism i s called a ___ | gene |
| In ___, hereditary information recombines from two organisms of the same species. In ___, hereditary information from different organisms is not combined. | Sexual reproduction, asexual reproduction |
| There are three main branches in the tree of life. Biologists call these major subdivisions of all organisms ___ | Domains |
| The three domains are ___, ___, and ___ | Bacteria, Archaea, Eukarya, |
| ___ divides all life into six major categories. The six kingdoms consist of four kingdoms within the domain Eukarya. | Kingdoms |
| Eukarya kingdoms are ___, ___, ___, and , ___ | Animalia, Plantae, Fungi, Protista |
| The kingdom in the domain of Archaea is ___ | Archaea |
| The kingdom in the domain Bacteria is ___ | Backteria |
| The branch of biology that studies organisms interacting with each other and with the environment is ___ | Ecology |
| Ecosystems are communities of ___ and their ___ | living species, physical environments |
| The process in which the inherited characteristics within population change over a generation is known as __- | Evolution |
| According to the theory of evolution by ___, organisms that have certain favorable traits ae better able to survive and reproduce successfully than organisms that lack these traits. | nautral selection |
| ___ are traits that improve an individuals ability to survive and reproduce | Adaptations |
| What are the Themes in Biology | I. Unity and Diversity of Life II. Interdependence of Organisms III. Evolution of Life |
| Vocabulary - Define: Development | The process in which cells change or differentiate for a specific purpose. |
| Vocabulary - Define: Reproduction | a process when organisms create a new organism through sexual or asexual reproduction |
| Vocabulary - Define: Organ | groups of tissues working together to perform a specific function |
| Vocabulary - Define: Tissue | groups of cells that work together and have similar abilities that allow organs to function |
| As the cells in a multicellular organism multiply, they become specialized for different functions in a process called___ | Cell differentiation |
| What are the 7 Characteristics of life? (Hint: Dograce) | D- DNA O- Organization G - Grow and Develop R - Reproduce A - Adapt C - Cells E - Energy |
| What is the difference between Domains and Kingdoms | Kingdoms are small groups tat exist in Domains. Kingdoms are subparts of a Domain |
| What is the difference between diversity of life and the unity of life? | All species are different so they are diverse in life, however, all species all share the same 7 characteristics of life. |
| What is the difference between Adaptations and Evolution | When organisms adapt to an environment, then evolution will occur. |
| What Kingdom and Domain are we in? | Domain: Eukarya - We have a nucleus and organelles Kingdom: Animalia |
| What is the difference between a Dependent and Independent variable? | If - Independent - What is being tested Then - Dependent - What is being measured |
| How are a hypothesis, a prediction, and an experiment related. | They are all related because if you have an observation, you can use these three steps together to form information about your observation or question. |
| Why is the cell the most basic unit of life | Cells are the smallest unit of life that carries out functions and all living things are made of cells |
| Give an example of homeostasis. | Examples: - Regulating body temperature - if it is cold you shiver but if you are hot you sweat. -Regulating Water- Drink too much you pee but not enough you get dehyrdated |
| Give an example of how TWO organisms are interdependent | Humans use plants for food, and those plants use carbon dioxide for photosynthesis. |
