Test Bank for Life Science with more than 100 Questions and Answers from Known Sources. Adaptation - ANSWERS This is an inherited characteristic that increases an organism's chance of survival. Air - ANSWERS The combination of gases in the Earth's atmosphere. Algae - ANSWERS Plantlike protists. These are multicellular protists often mistaken as belonging to the Plant kingdom. Amoeba - ANSWERS This is a type of protists that uses pseudopodia for locomotion and to engulf food. Amphibian - ANSWERS A vertebrate whose body temperature is determined by the temperature of its environment, and that lives its early life in water and its adult life on land. Analyze - ANSWERS This is to observe carefully and in detail so as to identify causes, key factors, or possible results. Angiosperm - ANSWERS A flowering plant that produces seeds enclosed in a protective fruit. Animal - ANSWERS This is an organism that is made of many parts but cannot make its own food. They are classified by whether they have a backbone or not. Annual - ANSWERS A flowering plant that completes its life cycle in one growing season. Arthropod - ANSWERS An invertebrate that has an external skeleton, a segmented body, and jointed appendages. Asexual reproduction - ANSWERS A reproductive process that involves only one parent and produces offspring that are genetically identical to the parent. Autotroph - ANSWERS An organism that is able to capture energy from sunlight or chemicals and use it to produce its own food. Auxin - ANSWERS A plant hormone that speeds up the rate at which a plant's cells grow and controls a plant's response to light. Bacteria - ANSWERS Singled-celled organisms that do not have nuclei. Basic Needs - ANSWERS These are the things needed for life: water, air, food, light, shelter, and space. Beak - ANSWERS This is an external anatomical structure of birds which is used for eating and for grooming, manipulating objects, killing prey, probing for food, courtship and feeding young. Behavior - ANSWERS This is the actions of organisms in response to stimuli. Biennial - ANSWERS A flowering plant that completes its life cycle in two years. Binomial nomenclature - ANSWERS The classification system in which each organism is given a unique, two-part scientific name indicating its genus and species. Body Temperature - ANSWERS This is what we are referring to when we say an animal is either warm blooded or cold blooded. It is one aspect of homeostasis. Budding - ANSWERS A form of asexual reproduction in which a new organism grows out of the body of a parent. Camouflage - ANSWERS This is a survival adaptation by which an animal blends in and is hidden in its surroundings. Carbon Dioxide - ANSWERS This is the gas produced as a result of respiration. Carnivore - ANSWERS This is an organism that gets energy by eating meat, living or dead. Cell - ANSWERS This is the structural and functional unit of all living organisms, and are sometimes called the "building blocks of life." Cell Membrane - ANSWERS A thin, flexible, semi permeable barrier around the cell which regulates what enters and leaves the cell. Cell Wall - ANSWERS This structure provides support and protection for plant cells. Cellular respiration - ANSWERS The process that releases energy by breaking down glucose and other food molecules in the presence of oxygen. Chlorophyll - ANSWERS This is a green pigment in chloroplasts that traps light energy from the sun. Chloroplast - ANSWERS An organelle in the cells of plants and some other organisms that captures energy from sunlight and changes it to an energy form that cells can use in making food. Chordata - ANSWERS This phylum includes the vertebrates, together with several closely related invertebrates. They are united by having, at some stage in their life, a notochord, a hollow dorsal nerve cord, pharyngeal slits and a muscular tail extending past the anus. Cilia - ANSWERS These are short hair-like organelles on the surface of a eukaryotic cell used for locomotion or sensory functions. Classify - ANSWERS This is to order or group by like or different properties. Claw - ANSWERS This is a curved, pointed appendage, found at the end of a toe or finger in most mammals, birds, and some reptiles. It is often used to refer to the hooked structures found on arthropods. Color - ANSWERS This is created when white light is passed through a prism; the wavelength of light that is reflected back to your eye. Conditioning - ANSWERS This is a behavior in which an animal learns that a particular stimulus and its response to that stimulus will lead to a good or bad result. Cone - ANSWERS The reproductive structure of a gymnosperm. Consumer - ANSWERS This is an organism that relies on other organisms for its food and energy supply; also called a heterotroph. Controlled experiment - ANSWERS An experiment in which only one variable is manipulated at a time. Cotyledon - ANSWERS A leaf produced by an embryo of a seed plant; sometimes stores food. Courtship - ANSWERS This is display behavior that certain animal species use to attract a mate for reproduction. Crustacea - ANSWERS This is the class of animals that possess two pairs of antennae, mandibles, an exoskeleton, and appendages with two branches. Cuticle - ANSWERS This is the protective waxy covering produced by the epidermal cells of leaves and often stems.
