What is it?
The sum total of all processes in an organism which convert energy and matter from outside sources and use that energy and matter to sustain the organism’s life functions
What is Metabolism?
Organisms that eat only organisms other than plants
What are Carnivores?
1. All life forms contain DNA and reproduce.
2. All life forms have a method by which they extract energy from the surroundings and convert it into energy that sustains them (metabolism).
3. All life forms can sense changes in their surroundings and respond to those changes.
4. All life forms are made of cells.
5. All living things grow.
6. All living things maintain a stable internal environment by regulating the chemical processes occurring in them (homeostasis).
What are four of the six criteria for life?
A suggested, testable answer to a well-defined scientific question or a testable explanation of observations.
What is a Hypothesis?
Living creatures that are too small to see with the naked eye.
What are Microorganisms?
The sum total of all processes in an organism which use energy and simple chemical building blocks to produce large chemicals and structures necessary for life.
What is Anabolism?
Organisms that eat both plants and other organisms.
What are Omnivores?
An organism is classified as a carnivore. Is it a heterotroph or an autotroph? Is it a producer, consumer, or decomposer?
It is a heterotroph and a consumer
An explanation of the natural world that has been tested with a significant amount of data/evidence from multiple experiments/observations.
What is a Scientific Theory?
The idea that long ago, very simple life forms spontaneously appeared through chemical reactions.
What is Abiogenesis?
The sum total of all processes in an organism which break down chemicals to produce energy and simple chemical building blocks.
What is Catabolism?
Organisms that eat only plants.
What are Herbivores?
An organism has receptors on tentacles that come out of its head. If those tentacles were cut off in an accident, this life function would be most hampered.
What is sensing changes in their environment and responding to those changes (or stimuli)?
A description of a natural relationship or principle, often expressed in mathematical terms, and supported by a significant amount of evidence.
What is a Scientific law?
A microscope that shines light through a specimen using two lenses to magnify an image.
What is a compound light microscope?
The process by which green plants and some other organisms use the energy of sunlight and simple chemicals to produce their own food.
What is Photosynthesis?
Organisms that produce their own food.
What are Autotrophs?
A parent and offspring are studied. Although there are many similarities between the parent and the offspring, there are also some differences. This is the method in which these organisms reproduce.
What is sexual reproduction?
TA logical interpretation based on prior knowledge, experience or evidence.
What is an Inference?
A microscope that transmits a beam of electrons through a thinly sliced specimen.
What is a transmission electron microscope?
Special structures that allow living organisms to sense the conditions of their internal or external environment.
What are Receptors?
Organisms that depend on other organisms for their food.
What are Heterotrophs?
An abrupt and marked change in the DNA of an organism compared to that of its parents.
What is a mutation?
The variable manipulated by the experimenter (aka changed by the scientist).
What is the Independent (or manipulated) Variable?
The most widely used system of measurement in science using meters, grams, liters and degrees Celcius.
What is the metric system (or SI, or the international system of units)?
