An introduction to Biology (Chapter 1)

What is the basic unit of life in biology? DNA cells molecules breathing and growing When using a triple beam balance, what unit is used? Meter Liter Gram Micrometer Throughout an experiment information is provided like a plant is 22 cm tall, it has 8 leaves, and 2 blooms. What type of data is this? quantitative data qualitative data irrelevant data biased data If someone was to measure the height of a stop sign, which metric unit would be the best to use? millimeters centimeters meters kilometers What is the dependent variable in this graph? Light Intensity lumens The Rate of photosynthesis The rate and light intensity Analyze this graph. What conclusion can be made? Light intensity does not affect the rate of photosynthesis The rate of photosynthesis increases indefinitely The rate of photosynthesis decreases as the light intensity increases The rate of photosynthesis increases until it reaches a certain intensity If plants are exposed to blue light, then the plants growth will increase the most. This statement is an example of A question A hypothesis A conclusion Qualitative data Plants that grew in blue light obtained the greatest growth compared to other colors. This statement is an example of A question A hypothesis A conclusion Qualitative data Chloe celebrated her birthday with cake, cupcakes, and ice cream. One hour after her celebration she noticed her blood sugar was 120 mg The ability for her body to recover from this and reach a normal sugar level of 80 mg is an example of homeostasis adaptation cell organization growth and development What characteristic of life is MOST concerned with the molecule of DNA? cellular basis of life hereditary information matter and energy maintaining homeostasis Matching key terms Match the term on the left with the best phrase or definition on the right observation The spider has hairy legs inference The ground will be soggy after the rain hypothesis An educated prediction about the investigation investigation studies only one variable at a time Conclusion According to the data, fertilizer does help produce more fruit Matching Body systems Connect the body system with the function or organs respiratory system lungs, diaphragm, trachea; exchange of gases within the cells circulatory system blood vessels and heart; create pathways for blood and nutrients to travel to every cell nervous system brain, spinal cord, nerves; sending messages to the cells of the body muscular system muscles, tendons, ligament; allows for movement in the body skeletal system bones; provides a framework for the body
