Unit 1 Review: Life, Scientific Method, & Microscopes

Using the picture, complete the story by filling in the blanks using the eight characteristics of life. Ecosystems, like the one illustrated, are full of life. Each living organism is made up of cells and has an organized structure that allows it to function in its environment. If you look closely, you will see the frog jumping, which is a response to stimuli, after the white-tailed deer approaches, seemingly scaring the frog. The white-tailed deer most likely approached the area to drink water and eat the reeds, a source of needed energy for the deer. Across the pond, you will notice two box turtles resting on a log. As the turtles sun themselves, they are able to keep their bodies warm, allowing them to maintain homeostasis. Additionally, the turtle's hard shell is a very important adaptation, which allows it to protect itself from predators. As all of this goes happens on land, underneath the many lilypads, which use asexual reproduction to make more of themselves, a school of small fish swims one direction, while a much bigger fish swims the other, representing that living things grow and develop. Match the words with the correct definition autotroph an organism that produces its own food heterotroph an organism that must consume other organisms to gain energy asexual reproduction when an offspring is the product of a single organism sexual reproduction When an offspring is the product of two organisms combining genetic material binary fission when a parent cell divides into two identical daughter cells structure and function how all organisms are organized A microscope stage should always be at its high point when you use the coarse adjustment knob. TRUE FALSE You should only use the fine adjustment knob when under which objective power? low medium high Label the parts of the microscope. Your word bank is as follows:revolving nosepiece body tube stage diaphragm scanning power objectivelow power objective high power objective stage clips eyepiecebase arm light source fine adjustment knob coarse adjustment knob body tube revolving nosepiece high power objective stage clips diaphragm light source base fine adjustment knob coarse adjustment knob stage arm eyepiece low power objective scanning objective Written as an IF, THEN statement, this piece of the scientific method is an educated prediction. problem conclusion hypothesis observations When conducting a scientific experiment, it must be: able to be replicated proven true the first time cheap and efficient based on your own thoughts and feelings only observation based on your five senses experimentation trials and error analysis qualitative descriptions and subjective quantitative number-based and measurable If you conduct a scientific experiment and your findings do NOT support your hypothesis, you should quit and disregard the entire experiment. TRUE FALSE What is a theory? scientific thought based solely on observation scientific thought based on minimal experimentation scientific thought based on much observation, research, experimentation, and data scientific thought based on educated predictions Label the independent and dependent variable on the graph.
