CELLS
Which part of the cell contains the genetic information needed for reproduction?
Nucleus
Which type of reproduction (sexual or asexual) produces diverse offspring? How do you know?
Sexual; asexual reproduction creates offspring who are identical to their parents (clones)
Who developed the first system for classifying organisms?
Artistotle
What does a fossil record allow scientists to develop?
A timeline showing the evolution of life from earlier species
A bee and a flower are an example of what type of symbiotic relationship?
Mutualism, both benefit from the relationship
Osmosis
Both parents passed on a recessive gene for blue eyes.
Who developed the modern system of classification in the 1700s?
Linnaeus
Explain the difference between a body fossil and a trace fossil.
Body fossils were parts of the organism, such as bones or teeth. Trace fossils include foot impressions, eggs, and burrows, and show the activities of an organism.
Name one way that humans have contributed to the extinction of organisms.
Urbanization, pollution, poor water quality, chemical and waste contamination, climate change, deforestation, overpopulation, and overconsumption
List the 5 levels of organization within multicellular organisms from smallest to largest.
Cells, Tissues, Organs, Organ Systems, and Organisms
In garden peas, round seed coats (R) are dominant over wrinkled seed coats (r). What will the result be of a cross between a purebred dominant male and a purebred recessive female? Create a Punnett Square to show your answer.
(See teacher for answer)
What characteristic distinguishes archaebacteria from eubacteria?
Archaebacteria live in extreme environments, while most organisms in Eubacteria live in moderate environments.
Define "survival of the fittest."
Organisms that survive long enough to reproduce must have favorable characteristics for their environment.
An abnormal drought combined with an extended period of hot weather can cause wildfires in some of Earth's biomes. Which biome would be least likely to experience a wildfire caused by these factors?
Tundra
Which 2 organelles are in plant cells but not in animal cells?
Cell walls & chloroplasts
In a specific species of plant, the allele for tallness is dominant over the allele for shortness. What type of plant should a tall plant be crossed with to determine whether it is homozygous or heterozygous?
A short plant
Name the group of single-celled organisms that have a nucleus.
Protists
Why do characteristics that are not beneficial to a species tend to decrease in frequency over time?
These characteristics have a low survival rate and are not passed on to offspring as often.
What is genetic engineering?
The manipulation of an organism's genetic information to produce new, more desirable characteristics for humans
A state of balance among all the body systems needed for the body to survive and function correctly.
In peas, yellow color (Y) is dominant to green (y). What will be the results of cross-pollination of a hybrid female and a hybrid male? Give the phenotype percentages of the offspring.
75% yellow & 25% green
An organism has the following characteristics: eukaryotic cells, cells have a cell wall, cells have chloroplasts, and it does not move. In which kingdom should this organism be classified?
Why are all fossil records considered to be "incomplete?"
Some organisms had soft bodies and did not form fossils.
What is the name for the aquatic ecosystem where freshwater from rivers and streams mixes with salt water from the ocean and nutrients and pollutants are filtered before they enter larger bodies of water?
Estuary
