Branches of Biology Flashcards
What is Biology
study of living things and their vital processes.
all living things share in common certain biological phenomena—give example.
various means of reproduction, cell division, and the transmission of genetic material.
What is the concept of homeostasis
living things maintain a constant internal environment
French physiologist Claude Bernard, who stated that “all the vital mechanisms, varied as they are, have only one object: that of preserving constant the conditions of life.”
Homeostasis, as currently defined, is a self-regulating process by which biological systems maintain stability while adjusting to changing external conditions.
What is evolution
Evolution is the change in heritable traits of biological populations over successive generations.
unity of origin of all living things. explain this concept
According to a theory proposed in 1855 by German pathologist Rudolf Virchow, “all living cells arise from pre-existing living cells.”
What is the basis for organic evolution
In his theory of natural selection, which is discussed in greater detail later, Charles Darwin suggested that “survival of the fittest” was the basis for organic evolution (the change of living things with time).
Evidence to support the theory of evolution has come primarily from?
the fossil record, from comparative studies of structure and function, from studies of embryological development, and from studies of DNA and RNA (ribonucleic acid).
What is diversity in biology?
Biodiversity is all the different kinds of life you’ll find in one area—the variety of animals, plants, fungi, and even microorganisms like bacteria that make up our natural world. Each of these species and organisms work together in ecosystems, like an intricate web, to maintain balance and support life.
It has been suggested that sexual reproduction became the dominant type of reproduction among organisms. Why?
because of its inherent advantage of variability, which is the mechanism that enables a species to adjust to changing conditions.
What does extant animal means?
currently or actually existing
What happens when a species is introduced into a new habitat
it either adapts to the change by natural selection or by some other evolutionary mechanism or eventually dies off. Because each new habitat means new adaptations, habitat changes have been responsible for the millions of different kinds of species and for the heterogeneity within each species.
concept of continuity
Whether an organism is a human or a bacterium, its ability to reproduce is one of the most important characteristics of life. Because life comes only from preexisting life, it is only through reproduction that successive generations can carry on the properties of a species.
