The lowest level of organization to have the characteristics of life is the __________ level. The organization of the body often is discussed in terms of six distinct levels of increasing complexity, from the smallest chemical building blocks to a unique human organism. Even though we cannot see cells without a microscope, they are the basic unit of life and they exhibit all of the characteristics of living organisms. Two or more atoms combine to form a molecule, such as the water molecules, proteins, and sugars found in living things. Atom, molecule, cell, tissue, organ, organ systems, organism, population, community, ecosystem and biosphere. Order of Biological Organization: Atom Atoms are the smallest units of matter that still retain the properties of an element. Always capitalize the genus name, but write the species in lower case. There are five levels: cells, tissue, organs, organ systems, and organisms. We never underestimate the power of an itsy-bitsy atom, which contrives the mysterious, gigantic universe. From smallest to largest (within the organism): Cell, Tissue, Organ, Organ System, Organism. The 11 organ systems include the integumentary system, skeletal system, muscular system, lymphatic system, respiratory system, digestive system, nervous system, endocrine system, cardiovascular system, urinary system, and reproductive systems. Different types of cells contain different amounts and types of organelles, depending on their function, (for example muscle cells use a lot of energy and therefore have many mitochondria while skin cells do not and have few mitochondria).

A community consists of all the different species within a certain area. The digestive system is located around the stomach area. At the highest level of organization, the biosphere is the collection of all ecosystems, and it represents the zones of life on earth. D. independant, Multiple choice: Scientific names should by italicized in print or underlined when writing The hierarchy of biological organization. During the run, the circulatory system helps the body breathe, the muscle system helps the bones move, and all the while the digestive system digests the food. Hierarchy of life, or Biological organization is the hierarchy of complex biological structures and systems that define life using a reductionistic (complex system is nothing but the sum of its parts) approach. John David Jackson, Patricia Meglich, Robert Mathis, Sean Valentine. (a) 2s,2p;2s, 2p;2s,2p; (b) 3p,3d;3p, 3d;3p,3d; (c) 3s,4s;3s, 4s;3s,4s; (d) 4d,5f4d, 5f4d,5f. C. observation What is the term for: joins together two or more related hypotheses. Organ system: It is a group of organs that work together to do one or more physiological function. C. hypothesis--final conclusion An example of this would be if a person eats a sandwich and then goes for a run. Science has greatly evolved over the years, there are new discoveries each time, and its a fact that right now we know a lot than we did thirty-five years ago. The digestive system is very important because without it, organisms would not be able to digest food. Mifflintown, PA 17059. Every type of cells transmits various tasks inside the human body regardless of their common functions, each, Organ system level this is a group of organs that work together to achieve a common role.

It consists of a positively charged nucleus that is made up of . Cells can be prokaryotic (without nucleus) or eukaroyotic (with nucleus). Includes molds, mushrooms, and yeasts. Atoms are made up of subatomic particles such as the proton, electron and neutron. Modeling is useful because observations made by ecologists can be used to test predictions based on those models. What is the term for: modifications that make an organism suited to its way of life. Therefore, it is sometimes called the building block of life. False, Multiple choice: These levels start from the smallest unit of life and work up to the largest and most broad category. What is the difference between them? Some living things contain one cell that performs all needed functions. The food ingested and assimilated by organism and its cells respectively, to provide energy, maintain life and to stimulate growth. Why or why not ? Tissue 14.
