Midterm Exam Flashcards
a permanent change in the genetic material of an organism
GENETIC•MUTATION
a watery liquid in the mouth that softens food for swallowing
SALIVA
a mass of cells that perform a specific function for the body
TISSUE
a type of asexual reproduction found in bacteria,
other prokaryotes, and a few eukaryotes
BINARY•FISSION
the observable genetic traits of an individual
PHENOTYPE
a trait or characteristic that improves an organism’s ability to survive in its environment
Adaptation
a trait or characteristic that improves an organism’s ability to survive in its environment
Adaptation
all possible genes for a trait
Alleles
an organism that breathes through gills in its larval stage and through lungs in its adult stage
Amphibian
the intentional reproduction of organisms with the sole desire of creating offspring with desirable characteristics
Artificial Selection
reproduction that involves only one parent and results in offspring that is genetically identical to the parent
Asexual Reproduction
a sensory receptor that detects sound
Auditory Receptor
unicellular organisms that sometimes have cell walls but do not have organelles and an organized nucleus
Bacteria
a type of asexual reproduction found in bacteria, other prokaryotes, and a few eukaryotes
Binary Fission
the smallest functional building block of an organism
Cell
a thin barrier that forms the boundary of cells
Cell Membrane
the outermost layer of cell in plants and some microorganisms
Cell Wall
a feature used to identify a person or thing
Characteristic
a threadlike strand in the nucleus of a cell that contains genetic information
Chromosome
the system that pumps blood through the body
Circulatory System
to create a new organism that is genetically identical to its parent; the organism created by the process of cloning
Clone
a photoreceptor in the eye that processes color vision
Cone
a mixture of water and salt that suspends the organelles within the cell
Cytoplasm
facts collected for reference and analysis
Data
the system that breaks down food into energy for the body
Digestive System
having two complete sets of chromosomes
Diploid
the process of making wild plants or animals suitable for human use
Domesticate
a trait that is expressed in an offspring if one parent contributes it
Dominant Trait
relating to electric and magnetic fields
Electromagnetic
an unborn or unhatched organism undergoing the process of growth and development
Embryo
a substance that catalyzes chemical reactions in the body
Enzyme
describes unicellular or multicellular organisms that have cells with a defined nucleus
Eukaryotic
the natural process by which species develop and differentiate from earlier forms of life
Evolution
the reproductive structure in flowering plants
Flower
a haploid male or female reproductive cell that forms a zygote
Gamete
a unit of hereditary characteristics that are passed from parent to offspring
Gene
the amount of genetic variation across an entire species
Genetic Diversity
inserting, deleting, or modifying the genetic material of organisms to gain desired characteristics
Genetic Engineering
a permanent change in the genetic material of an organism
Genetic Mutation
the complete genetic makeup of an individual
Genotype
