The organelle in which DNA resides.
What is the nucleus?
The formula mgh calculates this type of energy.
What is gravitational potential energy?
Isotopes of a given element will have a different number of this particle.
What is different number of neutrons?
What is a catalyst?
What is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change?
The scientist credited with coming up with the idea of inheritable traits.
Who was Gregor Mendel?
CxHy + O₂ → H₂O + CO₂ is this type of common reaction.
What is a combustion reaction?
Energy cannot be created or destroyed is a statement of this LAW in physics.
What is the Law of the Conservation of Energy?
Krypton-80 has this many protons and neutrons.
What is 36 protons and 44 neutrons?
The formula for nitric acid.
What is HNO3?
The difference between phenotype and genotype.
What is, genotype is the combination of alleles for a trait that an organism possesses; phenotype is the expression of these alleles.
An acid with a pH of 4 is this many times more acidic than an acid with a pH of 6.
What is 100x?
Heat always flows in this direction.
What is from areas/ objects or higher heat to areas/ objects of lesser heat.
The changes that occur in the parent nucleus during alpha decay.
What is a loss of 2 protons and 4 neutrons?
In order for chemical reactions to occur, particles need to do this.
What is collide?
Darwin's five steps leading to evolution.
What is: Overproduction, Struggle for existence (competition), Variation, Survival of the fittest, and Speciation
What is dinitrogen trioxide?
An example of this type of reaction would be Pb(NO3)2 + 2 KI ---> PbI2 + 2 KNO3
What is a double replacement reaction?
The half-life of an isotope is 12,000 years. If 87.5% of a sample of this isotope contains daughter isotope, how old is the sample?
What is 36,000 years old?
How nuclear fission leads to a chain reaction.
What is, fission can cause neutrons to be expelled as a large particle breaks up. These neutrons collide with large particles and cause them to undergo fission as well. Repeat.
A plant has blue flowers (a dominant trait: C) and tall stems (a dominant trait: S). It is crossed with a flower which also has blue flowers and tall stems. The F1 generation has offspring with blue flowers and tall stems and offspring with yellow flowers (recessive) and tall stems. What is the likely genotype of both parents?
What is CcSS?
The name for PbSO4 is this.
What is Lead (II) sulfate?
C8H18 + O2 ---> CO2 + H20 balanced is this.
What is 2C8H18 + 25O2 ---> 16CO2 + 18H20?
The key difference between nuclear fusion and nuclear fission.
What is, fusion is when two relatively small particles fuse together; fission is the splitting of a relatively large particle into smaller particles.
Write the answer to the following:
You are conducting and experiment where an amount of studying is your independent variable and your test score is your dependent variable. Write a hypothesis for this experiment.
What is: If I study more then my test score will be higher because I will be more familiar with the course material.
