Introduction to Bio
Chapter 1... section 1
| Question | Answer |
|---|---|
| Biology means ________ and list things that are studied in biology- page 4 | bio means life and logos is study ( biology= science of life)... origins and history of life, structure of living things (anatomy), how living things interact with each other ( ecology), how they function ( physiology) |
| What do biologist do as part of their career? (5 things) | study diversity of life ( learning about the organisms may help protect them), Research diseases (develop vaccines, look for new medicines), develop technologies such as bionic hands, improve agriculture and seek ways to prevent extinction. |
| Characteristics of living things include the following list ( page 7) | made of one or more cells, has organization (each organized structure has a specific function), grows and develops, reproduces, responds to stimuli, requires energy, maintains homeostasis, and has adaptations that evolve over time |
| What are to possibilities for organisms when it comes to their cells? | they can be unicellular ( 1 cell) or multicellular ( many cells) |
| The basic unit of life is a/an | cell |
| Structures in organisms have a relationship with their.... | FUNCTION ( each organized structure has a specific function...the structure of an anteater's snout relates to its functions... a container for an anteater's long tongue |
| What life characteristic is more important to a species than an individual | reproduction |
| reactions to internal or external stimuli are called | responses |
| When organisms take in food or make their own food this is because.... | Energy is required for all life processes |
| keeping internal conditions stable is a process called | homeostasis |
| When someone perspires to prevent their body temperature from rising too high their body is maintaining | HOMEOSTASIS |
| inherited changes that occur over time that help a species survive are called | adaptations |
| adaptations come from a process called ? .... it occurs over time | Evolution |
| a group of similar organisms that breed with one another and produce fertile offspring ( able to produce another generation) | species |
| when the last member of a species dies, the species becomes.... | extinct |
| something in an environment ( external or internal) that causes some type of reaction by the organism | stimulus |
| blood in the environment of a shark | a stimulus |
| the shark moving toward blood in the environment and attacking any organism present | response |
| metamorphosis or a biology student going through puberty would be an example of | development |
| natural changes that take place during the life of an organism | development |
| addition of mass to an organism ( making new cells in a multicellular organism)... unicellular organismss also grow ( but have a limited size before needing to reproduce) | growth |
| changes in a population over time is called .... this is how an organisms gets ? to help them survive better in their environment | evolution..... adaptations |
| What are two things that happen to the energy taken in by organisms? | energy is used for life processes ( growth, development, maintaining homeostasis, reproducetion etc.)... most of the energy is radiated to the environment as heat |
| processes to restore the normal state | homeostasis |
