Biology Life on Earth with Physiology Audesirk 2017 Updated Edition 2026 | A+ Graded Solutions Biology - answer - It is the study of all aspects of life and living things. Life is intangible and can't be simply defined. Organism - answer - It is an individual living thing. They all acquire and use materials and energy from chemical building blocks, maintaining organized complexity using energy, perceive and respond to stimuli, grow, reproduce, and have the capacity to evolve. Cell - answer - It is the smallest unit of life, having at least an outer membrane with a watery medium with organic molecules and genetic material of DNA. Photosynthesis - answer - It is the chemical reactions where light energy makes high-energy organic molecules, usually carbohydrates, from low-energy molecules, usually CO2 and H2O. Some cells use it. Deoxyribonucleic Acid (DNA) - answer - It is a molecule that is made of deoxyribose nucleotides and has the genetic information for living cells. It is carried on to offspring. Evolution - answer - It is the descent of modern organisms with modification form preexisting life forms, the theory that all organisms are related and have changed over time, and any change in the genetic makeup of a population from one population to the next. It is caused from differences in DNA among members of populations, inheritance of the differences, and natural selection. Population - answer - It is all the members of a species in a defined area at the same time and place and can interbreed. Changes in DNA are inevitable and cause evolution Gene - answer - It is the unit of heredity and a segment of DNA on a particular place on a chromosome with information of the amino acid sequence for a particular trait. Mutation - answer - It is a change in the base sequence of DNA in a gene and may alter the appearance of function of an organism. It is random copying errors and damage DNA. They become inherited, which may be harmful, indifferent, or helpful. Natural Selection - answer - It is the unequal survival and reproduction of organisms caused by heritable differences in phenotypes causing better adapted phenotypes being more common in a population. Adaptation - answer - It is a trait that increases the ability for an individual to survive and reproduce compared to individuals without the trait. Extinction - answer - It is the death of all members of a species. It happens when adaptation doesn't happen fast enough. Element - answer - It is a substance that cannot be broken down or converted into something simpler. Atom - answer - It is the smallest particle of an element that retains the properties of the element. Molecule - answer - It is a particle composed with one or more atoms held with chemical bonds and is the smallest particle of a compound that has properties of the compound. Tissue - answer - It is a group of cells that do something together. Organ - answer - It is a structure made of two or more distinct tissue types working together. Organ System - answer - It is two or more organs working together to do something. Species - answer - It is a basic unit of taxonomic classification. It is defined as populations that can interbreed naturally. Community - answer - It is the populations of different species that live in the same area and interact. Ecosystem - answer - It is all the organisms and their nonliving environment in a defined area. Biosphere - answer - It is all life on Earth and the nonliving portions that support life as well. Domain - answer - It is the broadest category for classifying organisms. They are Bacteria, Archaea, and Eukarya. Kingdom - answer - It is the second broadest taxonomic category with phyla under. Kingdoms make up domains. They are fungi, plants, animals, and protists. Unicellular - answer - It is single-celled, referring to Bacteria, Archaea and some Protista. Multicellular - answer - It is many-celled. Most Fungi, Plantae, and Animalia are multicellular, with co
