What are the seven properties common to all life?
Reproduction
Regulation
Growth and developement
Order
Process energy
Adaption
Respond to environment
What is reproduction
Members of a species create offspring of the same species
What is regulation
Adjusting oneself to a changing environment/ a organisms body attempting to maintain homeostasis
What is growth and development
An organism maturing into an adult
What is order
Cells of a living organism create complex ordered structures/ each part of the living thing has a specific place in its body
What is processing energy
Organisms gain energy and use it to keep them alive
What is adaption
Over generations, species adapt and improve to fit a changing environment
What is response to environment
Organisms change to respond to the environment
Describe the levels of biological organization from molecules to biosphere
Biosphere
Ecosystem
Community
Population
Organism
Organ system
Organ
Tissue
Cell
Organelle
Molecules
Atoms
Define concept of emergent properties and describe an example of it
New properties that show up as you go up the hierarchy of life
Life emerges in cells, whereas in organelles which make up cells there is no life
Why are cells a special level in biological organization
Cells are the first level in biological hierarchy that show properties of life
What are prokaryotic cells
Cells that are usually single celled, have no organelles, are smaller than eukaryotic cells, and have no membranes around the cell or in the cells organelles. domains include bacteria and Archea
What are eukaryotic cells
Larger cells that have organelles, a nucleus, a membrane
Compare dynamics of nutrients and energy in an ecosystem
Nutrients in an ecosystem are recycled. Nutrients in plants are eaten by animals, when animals die they are eaten by decomposers, who create nutrients for plants. It is a cycle
Energy in an ecosystem is inconsistent. Energy enters the ecosystem from the sun and is photosynthesized by plants, plants are eaten by animals, giving them energy, and energy is released as heat
Explain how DNA encodes a cells information
DNA stored within the cells nucleus. Nucleotides create chemical reactions in a double helix form. Each chain of chemical reactions contain genes and it from parents to offspring
Compare the three domains
Bacteria is unicellular prokaryotic organisms
Archaea were the first living things on earth. They are unicellular prokaryotic organisms that live in extreme environments.
Eukaryotes are mostly multicellular
Distinguish the difference between the three multicellular kingdoms with Eukarya
Fungi are decomposers that feed on other dead organisms and absorb their nutrients
Plantae are organisms (plants) that use photosynthesis to get their energy
Animalia eats other organisms to get energy
Describe the process and products of natural selection explain why individuals cannot evolve
Variation in a species is apparent. Change in environment benefits one variation of the species. The lesser variation of the species dies out. The variation with the favorable trait survives to reproduce
Asexual organisms do not experience natural selection because offspring are identical to the parent
Distinguish between quantitative and qualitative data
Quantitative data is data with number values. Qualitative data is well detailed sentences describing the experiment
What is the difference between inductive and deductive reasoning
Inductive reasoning starts with small observations and take those to create a larger idea
Deductive reasoning takes large ideas to prove specific results true
Distinguish between a scientific theory and a hypothesis
Scientific theory is a broad widely supported idea supported by much information
A hypothesis is a proposed explanation for a set of observations
Describe the structure of a controlled experiment and give an example
Question/ problem, observations, hypothesis, experiment, draw conclusions
A flashlight does not work, the batteries look old, if I change the batteries the flashlight will work again, put in batteries, it works
Compare the goals of science in technology explain why an understanding of science is essential to our lives
Understanding how genes work will help us understand how medicine is evolving to take genes from other species and use them to benefit human health
Explain how evolution impact the lives of all humans
DNA identifies individuals
