unit 1
Whhat is used to view very small objects
microscope
What are microscopic infectious particles that may cause diseases in humans
viruses
Which statement describes how the daughter cells could have their own flagella?
Daughter cells inherited the genes for the flagella.
Which of the statements describe how mineral fossils commonly form?
A dead organism settles down on the bottom of the water. It gets covered by sediment. Soft tissues decompose. Hard tissues are preserved.
Which option defines behavioral adaptations?
behaviors performed by an organism that increase its fitness
What is used to view distant objects
telescope
The scientific theory that describes cells and how they operate is called what
The cell theory
What are caused by differences in the structure of the face’s muscles.
Dimples
Ben is a scientist who digs for fossil remains. He finds a fossil in strata. He knows the area suffered multiple earthquakes and the strata are broken.
Can Ben use relative dating to date the fossils?
No. Relative dating assumes the fossils are in the layer they were originally in. Earthquakes may have moved the fossils
Which option correctly defines innate behavior and provides an example of one?
An innate behavior is an activity or behavior that occurs naturally in an organism. Baby sea turtles automatically moving to the ocean after hatching is an innate behavior.
What is used to determine presence and strength of radiation
radiation sensors
All living things are made of what
cells
Which option describes what genes are made up of?
Genes are made up of DNA.
Which option explains how radioactive atoms can be used to determine ages of fossils?
Radioactive atoms break down at a known rate. Scientists can measure the amount of radioactive atom remaining in a sample, and calculate its age.
Which option correctly defines learned behavior and provides an example of one?
A learned behavior is an activity or behavior that is taught to an organism. A dog sitting on command is an example.
What is used to study motion that’s too fast or slow to see, or to view objects in places that people can’t go
cameras
Which scientist published that all parts of a plant were made up of cells in 1838?
Schleiden
Which statement correctly describes how genes and chromosomes are related?
Genes are sections of chromosomes.
Sally is a scientist who searches for fossil remains. She finds a fossil near a major highway.
Can Sally use relative dating to date the fossils?
No, the presence of the highway would affect the outcome.
Which statement defines behavioral cycle?
a behavior that repeats at regular intervals
What is a method of science
observation
Which is a function of the cytoplasm?
helping the cell keep its shape
Which statement describes how DNA, chromosomes, and genes are related?
Chromosomes contain coiled up DNA. Genes are sections of chromosomes.
Which of the given statements is a pattern in the fossil record?
The Earth’s climate changed between hot and cold over time.
Which option is an example of migration?
Green sea turtles periodically move between Ascension Island and the coast of Brazil.
