Heterotrophs
|
Organisms that depend on other organisms for their food.
|
|
Mutation
|
An abrupt and marked change on other organisms for their food.
|
|
Theory
|
A hypothesis that has been tested with a significant amount of data.
|
|
Photosynthesis
|
The process by which green plants and some other organisjms use the energy of sunlight and simple chemicals to produce their own food.
|
|
Prokaryotic cell
|
A cell that has no distinct, membrane bounded organelles.
|
|
Species
|
A unit of one or more populations of individuals that can reproduce under normal conditions, produce fertile offspring, and are reproductively isolated from other such units.

|
AN ORGANISM IS CLASSIFIED AS A DECOMPOSER. IS IT AN AUTOTROPH OR A HETEROTROPH?
|
Heterotroph
|
|
A tiger develops lockjaw and can no longer open its mouth. Which of the four life functions will it not be able to perform?
|
Unable to eat: It is unable to extract energy from its surroundings and convert it into energy that sustains life

In laboratory studies, organisms from group A produce offspring with subtle differences are compared to the parents. Organisms from group B produce offspring that are identical to the parents, and organisms from group C produce offspring with marked differenes as compared to the parents. Which group reproduces asexually? Which reproduces sexually? Which group is experiencing mutations?
|
Group A - Sexually - slights differences from parents. Group B - Asexually - genetically identifical to parents (clones). Group C - experiencing mutations - mutations lead to abrupt and marked differences between offspring and parent to parents.

A biologist studies two organisms from the same family. She then studies two organisms from the same genus in that family. In which case do you expect the most similarity between organisms?
|
Two organisms from the same genus will probably have the most similarity, as a genus contains fewer species than a family.
|
|
A biologist wishes ot study how two remarkably different plants react to the same changes in their surroundings. Should he choose organisms from different phyla or different orders within kingdom Plantae?
|
He should choose organisms from different phyla, as the differences between organisms with a group are more pronounced the higher the group is in the classification scheme.
|
|
Why did the law of spontaneous generation survive for so many years?
|
It survived because flawed experiments seemed to confirmed it.
|
|
An organism is a multicellular decomposer with eukaryotic cells. To what kingdoms does it belong?
|
Multicellular decomposers are mostly in kingdom Fungi.
|
|
An organism is a multicellular autotroph with eukaryotic cells. To what kingdom does it belong?
|
Multicellular, eukaryotic organisms that make their own food are in Kingdom Plantae.
|
|
An organism has a single, prokaryotic cell. To what kingdom does it belong?
|
Organisms with prokaryotic cells are in kingdom Monera.
