Life Sciences Test Scope For Cycle Test Flashcards
To prepare for my Cycle Test this week
Biodiversity
The term used to describe the variety of organisms on earth, the interactions between them, and all of the natural processes.
Genetic Diversity
Refers to the variety and variation in a species
Species Diversity
The number of different species that are represented in a certain area
Key Species
A species that has a large effect on its environment relative to its abundance. Such species play a critical role in maintaining the structure of an ecological community.
Endemic Species
A species that is found only in a certain area
Ecosystem Diversity
The interaction within a specific ecosystem or between different ecosystems.
Symbiosis
Organisms that live co-dependently with one another and are unable to survive without the other
Mutualism
Both organisms benefit from the relationship
Obligate mutualism
When one of the organisms can’t survive without the other
Non-obligate mutualism
When the organisms don’t have to live with each other
Commensalism
Only one organism benefits from the relationship, the other is unaffected
Parasitism
One organism benefits from the relationships while the other is harmed
Taxonomy
A sub-division of systematics that is the science of defining groups of organisms on the basis of common characteristics and naming those groups
Domains
Eukaryotic, Archaea, Bacteria
Kingdoms
Monera, Protoctista, Fungi, Plantae, Animalia
TRUE or FALSE: The kingdom Animalia is divided into the invertebrates and the vertebrates.
TRUE

FILL IN THE BLANK: Whether typed or handwritten these scientific names must be __________.
underlined
FILL IN THE BLANK: If typed, because they are in Latin, they must be typed in _______.
italics
FILL IN THE BLANK: When first referring to the organism, ___ ______ ___ ___ ____ __ ____.

Q&A: Relative dating is the science of determining the relative order of what, without necessarily determining what?
A. future events, old age
B. dinosaurs, absolute age
C. past events, prehistoric age
D. past events, absolute age
D. past events, absolute age
Q&A: Absolute dating is the process of….?
A. falling in love
B. determining an approximate age in archaeology and geology
C. using chemical to break down organic materials of prehistoric time
B. determining an approximate age in archaeology and geology
Q&A: Which definition is the real meaning of radiometric dating (an absolute dating method)?
A. convert (a substance, molecule, etc.) into a radioactive form.
B. reproduction by means of a cell or organism dividing into two or more new cells or organisms.
C. a technique used to date materials such as rocks that contain elements. It is based on radioactive decay.
D. the branch of geophysics concerned with the magnetism in rocks that was induced by the earth’s magnetic field at the time of their formation.
C. a technique used to date materials such as rocks that contain elements. It is based on radioactive decay.
Q&A: Paleomagnetic dating is a type of dating method that is based on changes in the ___________ and intensity of the earth’s magnetic field that occurred over time.
A. orientation
B. sex orientation
C. life orientation
D. prehistoric orientation
A. orientation
TRUE or FALSE: (the list on the ‘formation of fossils’)
1. The organisms dies where it can be preserved into rock
2. The quickly-covering sediment occurs by sand or clay for aquatic and sand or mud for terrestrial
3. The soft part of the organisms are either slowly replaced by minerals or formed into a sponge
4. The cavity or impression could be filled with lava, leaving bread mould
FALSE.
- The organisms dies where it can be COVERED IN SEDIMENT AND IN ANAEROBIC CONDITIONS.
- The quickly-covering sediment occurs by sand or clay for aquatic and sand or mud for terrestrial.
- The soft part of the organisms are either slowly replaced by minerals or DISSOLVED LEAVING AN IMPRESSION OF THE NATURAL FORM
- The cavity or impression could be filled with MINERALS, LEAVING A MOULD
READ: The Cambric explosion gave the abundance of fossils from the Cambrian period, the event that began around 540 mya in that period, and the event during which most major phyla appeared, could have happened due to the changes in the atmosphere such as the increased oxygen levels.
The economically important minerals, coal and oil, can be explored for in the process of finding fossils since they are needed. Fossils are also used in the tourism industry to bring in tourists.
I have read the text section.
Types of Fossils
- Body fossils (skeletons, bones, wood, shells)
- Form fossils (sediments harden around an organism soon to be dissolved in acidic water)
- Mould fossils (cavity in form of fossils)
- Trace fossils (footprints, nail marks, tail marks)
- Unchanged fossils (insects in resin)
