Study Stack Lesson 5

Study stack for lesson 5 Biology

QuestionAnswer
Biomolecules Molecules made by living systems
Carbohydrates A biomolecule made entirely of carbon, hydrogen, and oxygen with a 2:1 ratio of hydrogen to oxygen
Lipids diverse hydrophobic biomolecules containing carbon, hydrogen, and oxygen
Tissues Cells that work together to perform specific functions
Nervous tissue reacts to stimuli and transmits signals throughout the body
Muscular tissue is specialized to contract and allow for movement of the body and its parts.
Epithelial tissue lines the surface of organs and the body cavities
Connective tissue is the most widespread tissue in the body and is specialized to connect and support other tissues; connective tissue ranges from bones, to blood, to fat tissue.
Levels of Organization in Biological Systems atoms, molecules, cells, tissues, organs, organ systems, and organism
Marine Biome Areas of salty water, such as the ocean. Marine ecosystems make up approximately 75% of Earth’s surface. Algae and plankton communities dominate these ecosystems as the basis of the marine food chain.
Freshwater Biome such as lakes and streams, are areas of water that have low salt concentrations. The dominant plant communities in freshwater biomes vary based on the particular area. Algae may dominate lakes, while marshes and bogs may have large population
Desert Biome biomes are characterized by low levels of rainfall and low population densities. Deserts are dominated by cacti and other drought tolerant plants
Forest Biome biomes are dominated by trees. The climate in these areas must have sufficient rainfall and nutrients in the soil to support these large plants
Grassland Biome biomes are dominated by grasses because these areas do not have sufficient water and nutrients to support large trees
Tundra Biome Cold temp regions. Because of the harsh, frigid conditions in these areas, they are sparsely populated. Tundra biomes are dominated by shrubs, low-lying grasses, and smaller vegetation.
Mutations change in the nucleotide sequence of DNA
Levels of Organization atoms, molecules, cells, tissues, organs, organ systems, organism, population, community, ecosystem, biome, biosphere
Atom Basic unit of matter
Molecule Smallest unit of most compounds the displays all properties of tat compound
Organelle Specialized structure that preforms important cellular cellular functions within a cell
Cells Basic unit of all forms of life
Tissue a group of similar cells that preform a specific function
Organ group of tissues that work together to preform closely related functions
Organ system An individual entity that preforms basic life functions
Population a group of individuals of the same species that live in the same area
Community assemblage of different population that live together in a defined area
Ecosystem all the organisms that live in a place together with their nonliving environment
Biosphere part of Earth in which life exists including land water and air or atmosphere
Reproductive System Produces Gametes
Digestive System Breaks Down Food
Immune System Protects body from Diesease
Nervous System Recognizes and coordinates the body’s response to changes
Circulatory System Transports Oxygen to cells
Muscular System Produces voluntary movement
Integumentary System Guards against ultraviolet light
Respiratory System Brings in oxygen for cellular respiration
Skeletal System Protects Organs
Endocrine System Controls Growth and metabolism
Homeostasis relatively constant internal physical and chemical conditions that organisms maintain
Feedback Inhibition The process in which a stimulus produces a response that opposes the original stimulus also called negative feedback. An example of this is if someone were trying to eat something they thought was unappetizing they would gag.
Liver Importance Controls your blood sugar
