Explain that cells are the basic unit of structures and function of living organisms. Cells are the basic unit of structures of living organisms because it is the smallest unit of life that is classified as a living thing, and is often called the building block of life. Cells are the basic unit of function of living organisms because all cells are made by other cells.

Basic units of life The basic units of life is made up of more or one cells. Cells are the basic unit of all living things. Those cells are produced by other cells.

Cells have different jobs Cells that have the same job combine together to form body tissue. (muscles, skin, or bone tissue) Groups of other cells make up the organs in our body's. (heart, liver, or lungs) Those organs have there own jobs, but all organs work together. They make up the systems in your body. Those systems keep you alive and healthy.

Animal Cell Eukaryotic Cell Has cell membrane Allows material to enter and leave the cell. Nucleus-contains DNA Mitochondria-energy is stored and used, contains DNA ER- transportation system within the cell Ribosomes- protein is made Vacuoles- closets, store stuff

Plant Cell Cell Wall Function is protection, support, structure. Chloroplasts Contain chlorophyll Make the plant green Function is to produce food

Explain the characteristics of life as indicated by cellular processes. The characteristics of life as indicated by cellular processes is movement, sensitivity, growth, excretion, reproduction.

Describe the process of cell division and development. The process of cell division and development is to growth of the cell population, where one cell grows and divides to produce two “daughter cells”..

Mitosis is... Is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets in two nuclei.eukaryoticchromosomescell nucleus

Meiosis is... Is a special type of cell division necessary for sexual reproduction. sexual reproduction

Explain the genetic mechanisms and molecular basis of inheritance. The genetic mechanisms and molecular basis of inheritance is that genetics deals with the molecular structure and function of genes, with gene behavior in the context of a cell or organism (e.g. dominance and epigenetics), with patterns of inheritance from parent to offspring, and with gene distribution, variation and change in populations. molecular structure and functioncellorganismdominanceepigenetics populations

Explain the flow of energy and the cycling of matter through biological and ecological systems (cellular, organismal, and ecological). The flow of energy and the cycling of matter through biological and ecological system is the integrated study of biotic and abiotic components of ecosystems and their interactions within an ecosystem framework..bioticabioticecosystems

Explain how evolutionary relationships contribute to an understanding or the unity and diversity of life The evolutionary relationships contribute to an understanding or the unity and diversity of life is the cycling of matter and flow of energy in living systems.

Explain the genetic mechanisms and molecular basis of inheritance. The genetic mechanisms and molecular basis of inheritance is that the inheritance of each trait is determined by "units" or "factors" that are passed on to descendents unchanged.

Explain the structure and function of ecosystems and relate how ecosystems change over time. The structure and function of the ecosystems is the characteristic structure of an ecosystem is obtained by the systematic physical organisation of the abiotic and biotic components of that particular ecosystem. Biotic- Living Abiotic- Non-living

Describe how human activities can impact the status of natural systems. Human activities can impact the status of natural systems by a great increase of phytoplankton in a water body. Negative environmental effects include hypoxia, the depletion of oxygen in the water, which induces reductions in specific fish and other animal populations.phytoplanktonhypoxia

Describe a foundation of biological evolution as the change in gene frequency of a population over time. A foundation of biological evolution as the change in gene frequency of a population over time is a remarkable amount of biological diversity appeared over approximately 10 million years.

Explain did natural selection and other evolutionary mechanisms account for the unity and diversity of past and present life forms. The natural selection and other evolutionary mechanisms account for the unity and diversity of past and present life forms by a process in which there is differential survival and/or reproduction of organisms that differ in one or more inherited traits.

Summarize the historical development of scientific theories and ideas, and describe emerging ideas. The historical development of scientific theories and ideas is to test them and try to figure them out. The emerging ideas are ideas that come straight to their minds and they are good ideas.
