variations.
theory of evolution.
The theory of evolution states that all organisms change over the course of time due to environmental/ Earth changes. Natural selection is the main mechanism driving this change. Yet, for life on Earth, there are many unifying characteristics that we all share that form an unbroken bond between all organisms. Energy and Matter, heredity and the genetic code, interrelationships among organisms. These are the "Big Ideas" that bind us all.
Each of the following are contributed toward the Living Systems of today:
Biochemistry and the "Big 4 Macromolecules"
The cellular nature of life
Metabolism and energy (Photosynthesis and respiration)
Heredity and the universality of DNA (gene control too)
Evolutionary mechanisms
Describe with all thorough explanations how the vast variety of species of living things came to be, and still tie in all of the similarities they share. How does each of ALL the mentioned above help shape the Unity and Diversity of Life on Earth? Include sources if…
Biological evolution is defined as a change in the
of a species over time.
survival rate
genetic makeup
number of individuals
number of offspring

- . Structure and function is a central theme to the study of biology. Each major group of organisms has evolved its own body part “tool kit" – a collection of structures that have evolved in ways that make specific functions possible. From capturing food to digesting it, and from reproducing to breathing, organisms use structures that have evolved into different forms as species have adapted to life in different environments. The structure of wings, for example enable birds and insects to fly. The structures of legs enable horses to gallop and kangaroos to hop. a. Think about your own teeth. What kinds of foods do you think human teeth are suited for? b. List at least three ways the structure of human teeth serves the function of eating these food materials. c. Now, finally apply the theme of structure and function to something you're very familiar with - your hands. List out all the ways you can think of that the structure of your hands serve the function of your hands.arrow_forwardDifferent species are distinguished by their diet. size. DNA. physical appearance.arrow_forwardNatural selection can be defined as: chance differences in organism traits. the chance for species numbers to increase rapidly. the processes that lead individuals to resemble their parents. the differential survival and reproduction of individuals. the genetic fixation of species.arrow_forward
- In order for natural selection to occur, organisms must (select all that apply) have a variation that can be passed from one generation to the next. have differential reproductive success. survive longer than another organism. have adaptations to their environment.arrow_forwardThe theory of evolution is the driving force for many scientific accomplishments, EXCEPT: - Understanding human (and non-human) gene functions -Understanding many biological consequences of climate change for humans as well as other organisms -The moon landing -Understanding how species coexist and interactarrow_forwardWhat is the correct order in the hierarchal levels of organization of life, from smallest to largest? cells, tissues, organs, organisms, and ecosystems cells, tissues, organs, organisms, and populations molecules, cells, organs, tissues, and organisms ecosystems, populations, tissues, cells, and organs atoms, tissues, cells, organs, and organismsarrow_forward

- The properties and processes of life would be correctly described by which of the following statements? Inherited information controls the pattern of growth but not the development of an organism. Organisms process energy during the course of their lives. Life is disordered. An organism's adaptations evolve over 2 or 3 generations.
