Living Things I
This characteristic of life can be accomplished in two ways: sexual and asexual
What is reproduction?
This is defined as an increase in the number of cells, or an increase in the size of a cell.
What is growth?
This is the mnemonic device to help you remember the 8 characteristics of life.
What is CORD GERM?
Maintaining a stable internal environment is called
Homeostasis
This kingdom is entirely prokaryotic and live in harsh environments
What is Archaebacteria?
This is the basic structure of a virus
When a tadpole becomes a frog, it is showing this characteristic of life.
What is Growth and Development?
False: "Movement" is not a characteristic of life, unless you count responding to a stimulus as movement. Plants will grow toward of source of light, but they aren't mobile, yet we still consider them alive.
Coal is an example of something that is
a. currently alive
b. not alive
c. material that was once alive
c. Was once alive
(coal is compressed, decomposed organic matter)
This is something that causes an organism to respond, such as a loud noise, light, odors, etc...
What is a stimulus?
The organisms in Kingdom Plantae have these three characteristics
What is eukaryotic, autotrophic and multicellular? (also cannot move)
Viruses have these characteristics of life
Has DNA, can evolve, can reproduce (within a host cell), can respond to stimuli
This characteristic of life is seen when an organism has an involuntary reflex, such as when you pull your hand away quickly from a hot stove top.
What is response to stimuli?
If an organism is made of many cells, it is called this.
What is multicellular?
The bacteria that causes staph infections on the skin is:
a. currently alive
b. not alive
c. material that was once alive
a. currently alive
It is a population of bacteria that is actively growing on someone's skin, using their cells for energy, and reproducing.
The type of reproduction which requires two parents; all animals, and some plants and fungi do this.
Sexual reproduction
A new organism is discovered on our planet. It is unicellular and lives in a watery environment. It has organelles and a nucleus, and it swims around using small hairs (cilia). What kingdom does it belong to?
What is Kingdom Protista?
Can viruses carry out metabolic functions such as taking in nutrients and releasing waste to survive?
No, they do not do this.
This characteristic of life is demonstrated when your brain reports that you are hungry when your blood-sugar gets low.
What is Homeostasis? (maintaining a stable internal environment)
This is the smallest unit of a living thing that still has ALL the characteristics of life.
What is a cell?
A granite rock is:
a. currently alive
b. not alive
c. made of materials that were once alive
b. not alive
Granite is made of minerals like quartz, silica and other materials that are NOT alive.
A change in a species' genes over time is the definition of
What is evolution?
This kingdom includes non-mobile heterotrophs that have a cell wall and break down dead/decaying matter.
What is the Fungi Kingdom?
A virus is not made of this, which is the smallest unit of life
What is a cell?
When the gene pool of a species changes over time, it is showing this characteristic of life.
What is evolution?
Give an example of an organism maintaining homeostasis
--Shivering when cold
--Sweating when hot
--Making less urine when dehydrated
A piece of cotton fabric is:
a. currently alive
b. not alive
c. made from material that was once alive.
c. material that was once alive
Cotton comes from a plant.
This is the genetic "code of life" that all living organisms have in common
What is DNA?
E. Coli, Salmonella, and Tetanus are three unicellular, prokaryotic organisms that can cause disease. What kingdom do they belong to?
What is Kingdom Eubacteria?
Viruses do NOT have these characteristics of life
Viruses are not made of cells, do not grow/develop, do not obtain energy, and do not maintain homeostasis
This genetic material is found in ALL living things.
This term is used for organisms that can make their own food to fuel their metabolism.
What is autotroph?
A container of yogurt is
a. currently alive
b. not alive
c. material that was once alive
a. currently alive
There are several different species of bacteria present in the yogurt that are actively using the milk sugar to make something called lactic acid, which makes the milk thicker and tangy.
This term is used to describe an organism that must consume other organisms in order to obtain energy.
What is a heterotroph?
This domain includes 4 kingdoms: Plantae, Animalia, Fungi and Protista
What is the Eukarya Domain?
Provide examples of different types of viruses
Influenza, COVID-19 (Sars CoV2), Measles, Chicken Pox, Common Cold (rhinovirus), HIV
