Living things Vocabulary
The increase in size of a living thing is called this.
Growth
This is the tendency of organisms to maintain a stable internal environment or "steady state".
Think: Balance
Homeostasis
An activity carried on by every living plant and animal is
(1.) reproduction
(2.) respiration
(3.) photosynthesis
(4.) transpiration
(2.) respiration
This is the removal of wastes from an organism.
Excretion
This is the taking in of food.
Ingestion
This is the energy molecule used by all cells.
ATP (adenosine triphosphate)
Homeostatic regulation of the body is made possible through the coordination of all body systems. This coordination is achieved mainly by
(1.) skeletal and excretory systems
(2.) respiratory and reproductive systems
(3.) nervous and endocrine systems
(4.) circulatory and digestive systems
(3.) nervous and endocrine systems
A characteristic of all known living things is that they (1.) use carbon dioxide
(2.) use atmospheric oxygen
(3.) carry on metabolic activities
(4.) are capable of locomotion
(3.) carry on metabolic activities
This is the one life process not necessary for any individual organism.
With this life process organisms make more of their own kind.
reproduction
This is the process by which food is utilized to provide energy in a form the organism can use.
Respiration
This is the sum TOTAL of all life processes or activities.
metabolism
This is the coordination of activities that MAINTAIN homeostasis in a constantly changing environment.
Regulation
Which term includes all the activities required to keep an organism alive?
(1.) metabolism
(2.) growth
(3.) nutrition
(4.) excretion
(1.) metabolism
In an ameba, materials are taken from the environment and then moved throughout its cytoplasm. These processes are known as
(1.) absorption and circulation
(2.) coordination and regulation
(3.) energy release and synthesis
(4.) food processing and energy release
(1.) absorption and circulation
This is the movement (circulation) of materials throughout an organism.
Transport
The study of living things is called this.
biology
Control of all physiological activities of an organism is necessary to maintain that organism's stability in its environment.
This life activity is known as
(1.) nutrition
(2.) regulation
(3.) transport
(4.) respiration
(2.) regulation
A characteristic of all known living organisms is that they
(1.) have complex nervous systems
(2.) require oxygen for respiration
(3.) carry on heterotrophic nutrition
(4.) originate from preexisting life
(4.) originate from preexisting life
Which activity is an example of the life process known as synthesis?
(1.) A large molecule is broken down into small molecules.
(2.) Starch is formed from the chemical bonding of glucose.
(3.) An organic compound is broken down and energy is released.
(4.) Oxygen moves into a cell through the cell membrane.
(2.) Starch is formed from the chemical bonding of glucose.
This is the making of larger more complex compounds from smaller compounds.
Synthesis
Respiration using oxygen.
aerobic
Explain how temperature homeostasis is maintained within the body when we get too cold or too warm.
When we get too cold, our muscles make extra energy to heat us by doing extra contractions (shivering). When we get too hot, our blood vessels carry blood closer to the surface of our skin, allowing us to lose heat more easily. Sweating and the evaporation associated with this also aids us in cooling our body. All these physiological mechanisms allow us to maintain temperature homeostasis.
Which life function provides substances that may be used by an organism for its growth and for the repair of its tissue?
(1.) nutrition
(2.) excretion
(3.) regulation
(4.) reproduction
(1.) nutrition
This is the overall process of taking in AND breaking down food to more soluble forms.
This is the breakdown of food particles to smaller, more soluble forms.
Digestion
