Biology
What is the term of the characteristics of life
DR.R COG
How many characteristics of life are there
6
What are all 6 characteristics of life
DNA, Reproduction, Responds to environment, Cell’s (pro and Eu), Obtains energy, Grows and develops
How can you tell the different of pro and Eu karyotic cells
The living organisms
What are the 2 main cells categories
Prokaryotic and Eukaryotic
Where is DNA stored
Nucleopalsm or Nucleolus
What happens to the DNA after a new child is born or organisms
DNA is inherited from an organism’s parent
What does “prokaryotic” mean
Pro=before kary=nucleus
What does “Eukaryotic” mean
“true” nucleus
Does prokaryotic have nucleus true or false
False
Where does prokaryotic keeps its DNA
The DNA is in cytoplasm
Where does Eukaryotic keeps it’s DNA
DNA is keep in it’s nucleolus
What are examples of organisms that are made up of
prokaryotic cells?
Bacteria
What are 2 types of cells are both eukaryotic cells?
Animal and fungi
Prokaryotic cells are the most complex cells. True or False
False
Eukaryotic cells evolved from prokaryotic cells. True or False
True
Which category of cells makes up unicellular organisms
((Prokaryote, Eukaryote, or both)?
Prokaryotic
How does cell multiplying
Reproduction
What are the two categories of reproducers?
Asexual and sexual reproduction
Which type of reproducer is made up of only one parent?
Asexual
Offspring from which type of reproducer develops from the
combination of receiving 50% chromosomes from a female
parent and 50% chromosomes from a male parent?
Sexual reproduction
Which type of reproduction requires 2 parents from each
gender (1 male, 1 female) to create offspring?
Sexual reproduction
How does offspring develop from asexual reproductions?
Asexual reproduction produces offspring that are genetically identical to the parent
What are cells?
The building blocks of all living things.
What are the 3 rules of Cell Theory?
- All living thing come form one or more cells 2. Cell are basic unit of life 3. All cell’s arise form a pre-exising cells
What does autotrophic mean?
requiring only carbon dioxide or carbonates as a source of carbon and a simple inorganic nitrogen compound for metabolic synthesis of organic molecules (such as glucose) autotrophic plants — compare heterotrophic.
Whats a food chain
Any organism that consumes other
organisms for food in order to create
energy for the body.
Define the characteristic: Obtains energy
to gain possession of; acquire; get
2 ways different organisms can obtain energy
Autotrophism and heterotrophism
Plants are heterotrophic. True or False
False
What type of organisms are heterotrophic?
organisms who cannot produce their own food are called as heterotrophs.
Define biotic
relating to or resulting from living things, especially in their ecological relations.
Define abiotic
physical rather than biological; not derived from living organisms.
What is growth/ developments
The increase of size and mass of an organism.
Define development
involves transformation of an organism as it goes through the growth process.
what is sensitivity?
The ability for any organism to respond to internal or external stimulus.
What does Homeostasis
The internal balance of an organism.
Define adaptations
the action or process of adapting or being adapted.
The classroom thermostat is broken and the room is very hot
and stuffy. How will your body internally respond to this
external stimulus?
the act of sweating to cool the body down is a response
Your day has been busy and you forgot to have breakfast
and then missed lunch. How will your body internally alert
you that it requires nourishment (food)?
Low blood sugar causes people to feel irritable, confused and fatigued.
What are membrane-bound organelles?
Membrane-bound organelles are cellular structures that are bound by a biological membrane. The membrane may be a single layer or a double layer of lipids and typically with interspersed proteins.
Which category of cells does not contain membrane-bound
organelles?
Prokaryotic
All categories of cells contain DNA. True or False
True
Which category of cells can create unicellular and
multicellular organisms?
Eukaryotic organisms
What is the formula for total magnification when looking
through a microscope?
Multiply the power of the ocular lens by the power of the objective being used.
What is the total magnification if the ocular lens is 10x and the objective being used in 40x?
400X magnification
