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  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
