| 8013606379 | biology (n) | The scientific study of life raises the obvious question: what is life? How to Distinguish living things from nonliving things? | 0 | |
| 8013606380 | 7 properties and processes of life | order reproduction growth and development energy processing regulation response to the environment evolutionary adaptation | 1 | |
| 8013606381 | Life's hierarchy of organization | Biosphere: all of the environments on earth that supports life Ecosystem: all organisms living in a particular area, as well as the physical components with which the organisms interact, such as air, soil, water, and sunlight Community: all organisms in an ecosystem Population: all the individuals of a particular species living in an area Organism: an individual living thing Organ system: consists of several organs that cooperate in a specific function Organ: made up of several different tissues, Tissue: made up of a group of similar cells that perform a specific function Cells: fundamental unit of life, made up of organelles Organelle: a membrane-enclosed structure that performs a specific function in a cell Molecules: a cluster of small chemical units called atoms held together by chemical bonds Atom: | 2 | |
| 8013606382 | emergent properties | New properties that arise with each step upward in the hierarchy of life. due to the arrangement and interactions of parts as complexity increases. | 3 | |
| 8013606383 | Prokaryotic cells | Cell that has its DNA NOT enclosed by a nucleus. There is no other organelles. First to evolve and were earth's sole inhabitants from first 1.5 billion years of life on earth. | 4 | |
| 8013606384 | eukaryotic cell | Cell that has its genetic material (DNA) enclosed by a nucleus ( membrane enclosed) and other organelles that bound by membranes. | 5 | |
| 8013606385 | Two basic types of cells | Prokaryotic cells and Eukaryotic Cells | 6 | |
| 8013606386 | systems biology | constructs models for the dynamic behavior of whole biological systems based on studying the interactions among parts. | 7 | |
| 8013606387 | Why are cells considered the basic unit of life? | They're the lowest level in the hierarchy of biological organization at which the properties of life emerge. | 8 | |
| 8013606388 | The dynamics of ecosystem include two major processes | The recycling of chemical nutrients The flow of energy | 9 | |
| 8013606389 | Explain how the photosynthesis of plants functions in both cycling of chemical nutrients and the flow of energy in an ecosystem | 10 | ||
| 8013606390 | Genes | DNA segments that serve as the key functional units in hereditary transmission (from parents to offspring) | 11 | |
| 8013606391 | Chromosomes | threadlike structures made of DNA molecules that contain the genes | 12 | |
| 8013606392 | The four building blocks of DNA | A, T, c G | 13 | |
| 8013606393 | Nucleotides | Basic units of DNA molecule, composed of a sugar, a phosphate, and one of 4 DNA bases | 14 | |
| 8013606394 | Where the diversity of life arises from? | From differences in DNA sequences, in other words, from variations on the common theme of storing genetic information in DNA. The DNA of genes provides the blueprint for making proteins, and proteins serve as the tools that actually build and maintain the cell and carry out its activities. | 15 | |
| 8013606395 | What is the chemical basis for all of life's kinship? | 16 | ||
| 8013606396 | The three domains of life | Bacteria, consist of prokaryotes, organisms with prokaryotic cells. Rod-shaped structure Archaea, consist of prokaryotes, organisms with prokaryotic cells. Round shaped and living in extreme environments Eukarya: consist of eukaryotes, organisms with eukaryotic cells. | 17 | |
| 8013606397 | Domain Eukarya | domain of all organisms whose cells have nucleus and organelles. including protists, plants, fungi, and animals | 18 | |
| 8013606398 | Protists | Single celled eukaryotic organisms and some relatively simple multicellular relatives. | 19 | |
| 8013606399 | Plantae Kingdom | Plants, which produce their own food by photosynthesis | 20 |
