Name the moon phase.
New moon
How can you determine if you are looking at a prokaryotic or eukaryotic cell under a microscope?
Prokaryotic cells do not have membrane-bound DNA (nucleus) while eukaryotic cells (plants and animal cells) do.
Calculating the rate of decay of a radioactive organism in sedimentary rock is known as what fossil dating method?
Atomic Mass - Atomic Number
How do you know the net direction of an object after calculating the net force?
Name the moon phase.
Full moon
Name the structure and its function.
Mitochondria produces ATP (energy) and carbon dioxide by metabolizing glucose through cellular respiration.
A population of a species that develops its own unique characteristics to help it survive and eventually leads to the development of a new species is called ____.
(THINK: divergent evolution)
Speciation
You calculate the displacement of the water in a graduated cylinder before and after an object is placed inside of it. What property are you measuring?
Volume
What is the net force and direction of the object?
17N to the right
What tide occurs during a full and new moon?
Spring tide
What is the function of this organelle?
It is the site of protein production
The DNA of a shark and goldfish is more similar to the DNA of a shark and dolphin. Which two organisms share a more recent common ancestor? Explain.
The shark and the goldfish because they share more DNA sequences that the dolphin
Neutrons
Which situation(s) shows an object moving upward?
Situation D
What is the moon phase and eclipse shown in the diagram?
New moon; solar eclipse
What structures do plant cells have that animal cells don't?
Cell wall for structure and protection and chlorophyll for photosynthesis.
Which is a more precise way to justify common ancestry between two species: comparing anatomy or comparing genes?
Would an isotope have a greater density if it had more or less neutrons? Explain.
It would have a greater density if it had more neutrons. In order to have more neutrons, the atomic mass would have increased. If the atomic mass increased, then that means the density also increased since the atoms are the same size.
Which situation(s) shows an object at rest?
A and C
Name the moon phase and the tide that occurs during this phase.
3rd quarter moon; neap tide
What does the mitochondria need in order to generate energy?
Glucose
In a field of pea plants that only grow 2 leaves, one pea plant randomly grew 4 leaves. In the next generation, there were more 4-leafed pea plants. How is this possible?
A mutation occurred that gave the pea plant 4 leaves. Since mutations are hereditary, the mutation got passed down to the next generation.
