Study Notes
Item 1
- A turtle retracting its head into its shell when a person approaches is an example of a response.
Item 2
- Offspring inheriting short, curved tails, like their parents is an example of heredity.
Item 3
- A new store and parking lot in a natural area is likely to harm salamanders by taking away their mating and egg-laying habitat.
Item 4
- The ecological levels of organization, from simplest to most complex are: population, community, ecosystem, biome.
Item 5
- A female polar bear giving birth during the Arctic summer is a response to changing environmental conditions. This behavior, as well as other evolutionary adaptations help polar bears survive and reproduce in the Arctic environment.
Item 1 (Page 6)
- Life on Earth requires energy from the sun.
Item 2 (Page 7)
- Metabolism is the collection of chemical reactions an organism does.
Item 3 (Page 8)
- Some aquatic frogs spending the winter hibernating at the bottom of lakes and ponds, is an example of a response to environmental conditions, particularly the cold weather of winter.
Item 4 (Page 9)
- Sweating during exercise helps maintain homeostasis by regulating body temperature.
Item 5 (Page 10)
- Unicellular organisms perform all life functions within their single cell.
Item 1 (Page 11)
- The question "Does the tail length of a male sparrow influence the female's choice of mate?" can be answered with scientific methods.
Item 2 (Page 12)
- The scientific method steps in correct order are: make observations, form a hypothesis, conduct an experiment, gather and analyze data, draw conclusions.
Item 3 (Page 13)
- Experiments measure the dependent variable.
Item 4 (Page 14)
- In a plant experiment testing the effectiveness of fertilizers, plant height is the dependent variable.
Item 5 (Page 15)
- Based on the data in the provided table the conclusion that can be drawn, is; Fertilizer A was more effective than Fertilizer B.
Item 1 (Page 16)
- A scientist using scientific methods might observe, analyze, and conclude patterns in data about a phenomenon.
Item 2 (Page 17)
- Relevant questions about the behavior of female digger wasps include: "How many eggs does she lay at a time?" "How does she know where her nest is located?")
Item 3 (Page 18)
- Scientific methods have evolved over time, with new technologies adding to and improving observation, experimentation, and analysis, leading to a more in-depth discovery of natural phenomena.
Item 4 (Page 19)
- Jane Goodall observed chimpanzees in the wild making and using tools, drawing conclusions about the animals' behaviors.
Item 5 (Page 20)
- Scientists develop hypotheses using observations, experiences and reason.
Item 1 (Page 21)
- Fat cells expanding to store energy is an example of structure relating to function.
Item 2 (Page 22)
- Red blood cells being shaped like smooth discs allows them to flow efficiently through blood vessels, fulfilling their function of carrying oxygen.
Item 3 (Page 23)
- The spongy structure of lungs allows for maximum gas exchange with the environment.
Item 4 (Page 24)
- Broad flat leaves on plants are an example of structure (leaf shape) matching function (light absorption) but not being the best structure for all conditions.
Item 5 (Page 25)
- The stomach’s lining being acid-resistant relates to the function of digesting food in harsh acidic conditions.
