COMPLETE ANSWERS RATED 100%
CORRECT
What are characteristics of living things - correct answer ✔✔1. Living things contain nucleic
acids, proteins, carbohydrates, and lipids.
2. Living things are composed of cells
3. Living things grow and reproduce
4. Living things use energy and raw materials
5. Living things respond to their environment
6. Living things maintain homeostasis
7. Populations of living things adapt and have adapt traits
Metabolism - correct answer ✔✔refers to all chemical reactions that occur within the cells of
living things. Metabolic activities extract energy from various nutrients and transform it to do
different types of work.
Homeostasis - correct answer ✔✔the relatively constant and self correcting internal
environment of a living organism. Homeostasis keeps body temperature within its limits for
survival.
Adaptive traits - correct answer ✔✔traits that help it survive and reproduce in its natural
habitat
Population - correct answer ✔✔individuals in the same species living in distinct geographic area
, example: four-eyed butterfly fish living in a coral reef
Community - correct answer ✔✔all living species that can potentially interact in a particular
geographic area
example: all species living in a coral reef
Ecosystem - correct answer ✔✔all the living organisms in a community along with their physical
environment
Biosphere - correct answer ✔✔The part of the earth that supports life. The layer of the earth
where life lives.
Example: If the earth were a basketball the biosphere would be the orange paint
Science - correct answer ✔✔A systematic approach to answering those questions, a way of
acquiring knowledge through carefully documented investigation and experimentation- the
scientific method
The Scientific method - correct answer ✔✔1. Make careful observations, and ask a question
about the observation
2. Develop a testable hypothesis as a possible answer to your question
3. Make a prediction based on your hypothesis, and test it with a controlled experiment
4. Draw a conclusion based on the result of the experiment
5. Make new predictions and test them.
Controlled Experiment - correct answer ✔✔An experiment where the subjects being tested are
split into two groups; the control group and the experimental group
