Scientific Method
the group in the experiment which allows the experimenter to assess the effect of any unforeseen variable. It usually represents “normal” conditions.
Contol
What percent of the atmosphere is Nitrogen
78%
Cell Membrane
lets certain things in and out of the cell.
Genetics
the study of heredity
What are the different magnifications of a microscope?
4x 10x 40x 100x
Make a hypothesis is what # in the scientific method?
2
True or False?
Hydrogen is present in the atmosphere
False
Vacuole
cleans up all the waste
Genes
section of a chromosome that codes for a specific trait
What is the lowest magnification
The lowest magnification is 4x
Analyze the data is what # step in the scientific method?
5
What is special about the Mesosphere?
where most meteors, or space rocks and metal, burn up before they can crash to the ground.
Mitochondria
makes energy for the cell.
Alleles
form of a trait (dominant or recessive for example, or tall or short)
How do you calculate total magnification?
Multiply the magnification of the microscope by the eyepiece of the microscope.
the variable which responds to the changed variable.
Dependant Variable
What are some known greenhouse gasses
Methane, and CO2
Chloroplast
performs photosynthesis
Homozygous
two of the same alleles (TT or tt)
True of False.
There is a 1000x on our microscopes
False
the variable which is purposely changed by the experimenter.
Independant variable
What is special about the Troposhere?
The air is densest in this lowest layer
Lysosome
breaks down waste
How is codominance different from regular genetics?
Both alleles are not strong enough to cover up the other.
True or False?
There is a 40x on a microscope
True
