- inheritance of acquired traits
- a Green, leaflike structure that encloses and protects the unopened flower bud.
- b The rolling motion of smooth muscle that moves food along the alimentary canal. Includes the passage from the esophagus to the stomach, the churning action of the stomach, and the passage through the small intestine.
- c Usually unicellular and microscopic, spores are produced by protist molds, fungi, and plants and are able to develop into new individuals. Spores are able to survive without food or water for long periods. Most fungi spend part of their life cycle as hyphae and part as spores.
- d A sugar compound consisting of two carbohydrate monomers.
- e A crucial, and incorrect, aspect of Lamarck's theory of evolution. Lamarck believed that the traits a parent acquired during its lifetime would be passed on to its offspring.
5 Multiple choice questions
- The process by which plants and other autotrophic organisms convert light energy into organic materials, such as glucose.
- Fingerlike projections in the small intestine that increase surface area and maximize the absorption of nutrients.
- The first population to move into a geographic location and begin the process of ecological succession.
- The theory, first proposed by Darwin, which holds that organisms produce as many offspring as possible, which compete for limited resources. Organisms' characteristics vary, and certain characteristics will allow organisms to survive and reproduce more effectively. These adaptive characteristics will be more prevalent in subsequent generations. Natural selection is the engine of evolution, choosing the most fit genes to pass from one generation to the next.
- Autotrophic organisms such as plants, plankton, and chemosynthetic bacteria that are able to synthesize organic compounds using energy from the sun or chemical reactions. Producers do not have to consume other organisms to attain energy and are the foundation of every food web.
5 True/False questions
endotherm → See cold-blooded.
aorta → Protein filaments that, along with myosin, allow muscles to contract.
ecology → The study of the interactions and relationships of populations with each other and their abiotic environments.
learned behavior → Behavior that an organism picks up over the course of its life. Three types of learned behavior are habituation, conditioning, and associative learning.
decomposer → Organisms that consume waste products and dead organic material and constitute part of the food web, which also includes producers and consumers. Also called saprophytes. Decomposers liberate inorganic elements such as nitrogen and carbon and allow those elements to move back into their respective chemical cycles. Examples of decomposers are bacteria and fungi.
