Question | Answer |
Which group contains single-celled organisms? | fungus |
What conclusion can be made about earthworms because they do NOT have an internal skeleton? | They are invertebrates. |
Organisms can be separated by their most basic characteristics into the broadest groups known as | domains |
The classification of some organisms has changed. What new process is used to reclassify organisms? | Structures are now examined at the molecular level. |
Single-celled organisms that cause disease can be found in which domain? | Bacteria and Eukarya |
Some prokaryotes once classified in the domain Bacteria are now classified as | Archaea |
How are organisms classified as Eukarya different from organisms classified as Archaea and Bacteria? | They all have membrane-bound nuclei. |
Prokaryotes that live in extreme environments. | Archaea |
Which system groups life forms by Domains? | Archaea, Eubacteria, Eukaryota |
Which cellular organelle modifies fatty acids? | endoplasmic reticulum |
Statements that are TRUE for plant cells and FALSE for animal cells. | Plant cells make their own food, but human cells do not. |
Which body system is responsible for breaking down food into molecules that it absorbs? | digestive |
What part of the body receives information from the senses? | brain |
Which two human body systems are MOST responsible for getting oxygen to cells? | circulatory and respiratory |
Which of these is a function of all cells? | to transfer genetic information from one generation to the next |
Which of these is the basic building block of complex organisms? | a cell |
How do muscles and bones work together to create body movement? | The muscles pull on the bones. |
The nucleus of the cell controls cell activity. Which body system performs a similar function in humans? | central nervous system |
A child's sex is determined by the sex chromosomes of which person? | father |
Which of these cell parts contain instructions for the passage of traits from one generation to the next? | chromosomes |
DNA stores the genetic instructions transferred from one generation to the next. What is DNA? | a molecule |
Which of these cell parts store genetic instructions for the entire organism and transfers them from one generation to the next? | DNA molecules |
What is the definition of heredity? | The passage of genetic information from one generation to the next. |
Some fungi can reproduce either asexually or sexually, resulting in offspring with different characteristics. Sexually produced offspring have | a combination of genetic material from each parent cell. |
This is a part of the process of sexual reproduction. | pollination |
Potatoes reproduce by growing sprouts on their surfaces. When planted, these sprouts grow into new plants. This is an example of | asexual reproduction |
A statement which describes a characteristic of both sexual and asexual reproduction | New cells are produced |
What is a benefit of sexual reproduction? | Ability to produce genetically different offspring. |
What structure is found in producers in nearly all ecosystems? | chloroplasts |
A statement that explains why photosynthesis is the foundation of most food webs. | Sunlight is the source of energy for nearly all ecosystems. |
How does the water in an estuary compare to the water in the open ocean? | Estuaries have more concentrated nutrients and less concentrated salt. |
A true comparison of ecosystems. | Grasslands get more rain than deserts. |
What is a true of mutualistic relationships among organisms? | The organisms cooperate with each other. |
In a completely cooperative relationship, each organism benefits equally. What sequence lists these relationships in order of increasing cooperativeness? | predation, parasitism, commensalism, mutualism |
A statement that describes two species of animals that live in biological coexistence with each other. | They live in the same area but have different food and nesting needs. |
Animals depend on plants for many things, including food. What do plants depend on from animals? | carbon dioxide |
This statement best describes biomes. | Large ecosystems that have distinctive organisms and a particular climate. |
As members of a food web, humans are considered to be | consumers |
What has to happen for an inherited trait to increase in a population? | Organisms with the trait need to bear more offspring than organisms without the trait. |
As some organisms die, their remains become buried by mud and are eventually compressed into a type of rock. What rock type forms from this process? | sedimentary |
Fossil records indicate that species changes generally.\ | take place over many generations |
What factor MOST accurately describes the statement "survival of the fittest" in relation to natural selection? | The ability of offspring to reproduce |
In what scenario would natural selection MOST likely occur? | centuries of gradual climate change |
While digging in the side of a hill, students found fossils in the rock layers. From the fossils they uncovered, what was the MOST likely progression of environments in that area? | It was first a forest and then became a lake. |
Diversity among members of a species is important because diversity | increases the chances of survival under changing conditions. |
In what type of rock would a geologist MOST likely find evidence of ancient life? | sedimentary |
Sedimentary rock helps scientists piece together the history of Earth MOST likely using clues from | fossils |
What would help determine the changes in a plant species over geologic time? | examining the fossil record of the plant |
