Beaks of Finches

Building block of Starch
What is a simple sugar or glucose?
100
Site of cellular respiration
What is mitochondria?
100
Three differences between RNA and DNA
What are
1. DNA is a double helix, RNA is single stranded
2. DNA has thymine, RNA has uracil
3. DNA cannot leave the nucleus and RNA can

All of the robins in the courtyard
What is a population?
100
What was the main objective of the Clothespin Lab?
The main goal was to show how traits that help survival can become more common in a population over time.
100
What did Darwin observe about the finches on the Galápagos Islands?
Darwin noticed that finches on different islands had different types of beaks, each suited to the food available on that island.
200
Building block of lipids
What is three fatty acids and a glycerol?
200
Three things a plant cell has that an animal cell does not
What are cell wall, one large vacuole, chloroplasts
200
Describe transcription and translation
What are
Transcription: copying the DNA into mRNA so it can go to the ribosome for protein synthesis
Translation: the ribosome reads the mRNA one codon at a time and the tRNA brings in the correct anticodon with the amino acid attached
200
The processes in the carbon cycle
What are photosynthesis and respiration?
200
Describe how the lab demonstrates the concept of natural selection.
The lab shows that the "fittest" survive and get passed on, just like animals with traits that help them survive in nature.
200
How do beak shapes relate to the diet of finches?
The shape of a finch’s beak helps it eat certain types of food. For example, big beaks help crack seeds, and small beaks help catch insects.
300
Name the parts of the nucleotide below.
What is
A: 5 carbon sugar
B: phosphate group
C: Nitrogenous base
300
Reactants of photosynthesis
What are water and carbon dioxide?
300
The relationship between a honeybee and a flower
What is mutualism?
300
What variables did you control during the experiment?
We controlled things like how fast we picked up the clothespins and the distance, to make sure the results were fair.
300
What is the significance of the finches in the study of evolution?
The finches helped Darwin understand how species change over time, based on what traits help them survive in their environment.
400
Describe what happened in the image below
What is starch indicator moved into the cell causing the inside to turn black?
400
Describe one benefit of the process below and one drawback
What are
Benefit: all animals have the desired trait
Drawback: if one organism is susceptible to a disease, they all will be or you cannot mate the flock because they are all the same gender
400
Three causes of global warming
What are
1. Burning fossil fuels
2. Cow flatulence
3. Deforestation
400
How did the results support or challenge your hypothesis?
The results showed that the easiest-to-grab clothespins were picked more, supporting the idea that traits that make survival easier are more likely to be passed on.
400
Describe how environmental changes can affect finch populations.
Changes in the environment, like a drought, can change what food is available, so finches with beaks that can eat the available food are more likely to survive and have babies.
500
An enzyme only works on one substrate
What is "Lock and Key"?
500
Explain what happened to the cell below
A saline solution was added which caused water to leave the cell so the cell membrane shrunk
500
The process used to diagnose chromosomal mutations during pregnancy
What are amniocentesis and karyotyping?
500
Which organism would be affected the most if toxins were released into the water supply and why?
What is the eagle?
Top level consumers need to eat more to fulfill their energy needs so toxins build up in the bodies.
500
Discuss how this lab relates to real-world evolutionary concepts.
This lab relates to how animals with helpful traits survive better and have more babies, passing on those traits to the next generation, just like natural selection in the wild.
500
Explain how the beaks of finches provide evidence for natural selection.
Finches with the best beaks for their environment are more likely to survive and pass on those traits to their babies, showing how natural selection works.
