What is the first step of the Scientific Method?
Observation
Evolution is just a guess
True or False?
False - In science, a theory is a well-substantiated explanation based on evidence, experimentation, and repeated testing. The theory of evolution is supported by vast amounts of data, including fossils, genetics, and observable phenomena. It is not a "guess" but a comprehensive framework for understanding how species change over time.
What does the theory of evolution explain?
A) How species change over time
B) The origin of life
C) Why some organisms are perfect
D) None of the above
A - How species change over time
There is not a lot of scientific evidence for evolution.
True or False?
False - There is an overwhelming amount of evidence supporting evolution, including fossils, genetic data, comparative anatomy, and observable changes in populations. Evolution is one of the most well-supported ideas in science.
What is the difference between abiotic and biotic factors?
Biotic are living components of an ecosystem and Abiotic and are the non-living components of an ecosystem
What is the correct format to write hypothesis in?
If... then... because...
Evolution is still happening today.
True or False?
True - Evolution is still happening today. An example is the way cockroaches have evolved to survive in different environments, including developing resistance to certain pesticides over time.
Evolution is primarily concerned with the origin of humans.
True or False?
False - Evolution is the study of how populations of organisms change over time through processes like natural selection, mutation, and genetic drift. While human evolution is a part of this larger field, it is not the main focus. Evolution applies to all life forms, not just humans.
Evolution takes thousands of years to occur.
True or False?
False - While some evolutionary changes take thousands or millions of years, others can happen much more quickly. For example, bacteria can evolve resistance to antibiotics in just a few generations, and observable changes in species, like Darwin’s finches, have occurred in just a few decades.
In a food chain, what do we call organisms that produce their own food, such as plants and algae?
Producers
What is the name of the variable that is purposefully changed? (the "mess around" variable)
Independent Variable
Natural selection is one mechanism of evolution.
True or False?
True - Natural selection is a process where organisms with traits better suited to their environment are more likely to survive and reproduce, passing those traits on to the next generation. It is one of the key mechanisms that drive evolution.
What drives evolution?
A) Random mutations
B) Natural selection
C) Environmental changes
D) All of the above
D - All of the above
What type of molecular evidence supports shared ancestry between humans and chimpanzees?
A) Fossil evidence
B) Similar DNA sequences
C) Vestigial structures
B) Similar DNA sequences -
In which biome would you find animals like polar bears and seals?
Tundra
Why is it important to repeat experiments multiple times?
Repeating experiments ensures reliability and helps verify the results.
Evolution is something that happens to individual organisms.
True or False?
False - Evolution occurs at the population level, not the individual level. Individuals do not evolve; instead, the frequency of traits in a population changes over generations due to natural selection, mutations, and genetic drift.
Evolution involves individuals changing in order to adapt to their environment.
True or False?
False - Evolution doesn’t happen during an individual’s lifetime; it occurs over many generations in a population. Individuals with traits better suited to their environment are more likely to survive and pass those traits to future generations. Over time, this leads to the evolution of populations, driven by natural selection, while adaptation helps drive this process.
Which of the following provides evidence for the evolutionary relationship between species?
A) Analogous structures
B) Embryological development
C) Homologous chromosomes
B – Embryological development.
Similarities in embryonic development across species suggest a shared evolutionary history. For example, early embryos of vertebrates look remarkably similar before developing into distinct species.
What is the process by which plants use sunlight to absorb carbon dioxide from the air and produce oxygen?
Photosynthesis
What are constants in an experiment? Provide an example.
Constants are factors that remain the same throughout an experiment to ensure a fair test. Example: Using the same type of plant in a plant growth experiment.
According to evolution, people came from monkeys a long time ago.
True or False?
False - Evolution does not say that humans came from monkeys. Instead, humans and modern monkeys share a common ancestor that lived millions of years ago. Over time, different evolutionary paths led to modern monkeys and humans as separate species.
Which of the following is not part of the theory of evolution?
A) Genetic variation exists in populations
B) Organisms inherit traits from parents
C) Species are fixed and unchanging
D) Natural selection occurs
C - Species are fixed and unchanging
Which of the following is an example of homologous structures providing evidence for evolution?
A) The wings of a bat and the fins of a dolphin
B) The similar arm bones in humans, cats, and whales
C) The eye of a squid and the eye of a human
B – The similar arm bones in humans, cats, and whales.
Homologous structures are body parts that are similar in different species due to shared ancestry. The arm bones of humans, cats, and whales show a common evolutionary origin.
What is the term for the process in the water cycle that involves water turning into gas and rising into the atmosphere?
Evaporation
