Example Question #1 : Diverse Life Cycles Of Organisms
Samantha and Gordon are creating a model of an organism's life cycle. They choose the butterfly as their project focus. The project is due in one month. Samantha says they should create sculptures and paint pictures of butterflies as their model. Gordon thinks they should watch a butterfly transform from an egg, to caterpillar, to chrysalis, and finally to butterfly and take photos along the way.
Whose model (if any) is more realistic and why?
There is not enough information to tell who has the best plan for a model. More details would need to be given to make a selection.
Neither; Both of their ideas for a model are terrible. Sculptures, pictures, and photographs are not models.
Gordon; He is correct because his model is most reasonable to complete in a month and would show the complete life cycle.
Samantha; She is correct because her model is artistic, reasonable and would be the most attractive.
Gordon; He is correct because his model is most reasonable to complete in a month and would show the complete life cycle.
In this scenario, Gordon's model is the most realistic and would be the best choice for the project. A month is enough time to watch the butterfly move through its life cycle, and taking detailed photographs would show others what they witnessed. The photos could be put in a ring or a timeline to show the progression over time.
Example Question #6 : Diverse Life Cycles Of Organisms
Gage has to create a life-size model of an organism during its life. He has selected the grasshopper. Which stage(s) of life would be most realistic to use for his model?
Egg
Nymph
All answer choices are correct.
Adult
All answer choices are correct.
Gage can make a life-size model of any of the grasshopper's stages of life. The grasshopper starts as an egg, then a nymph, and finally an adult. Each is a reasonable size and can be recreated. A grasshopper's egg can be tiny, but it is possible to make a model.
Example Question #2 : Develop Models Of Organisms' Life Cycles
Carol has to make a model of a palm tree's life. What would be the worst title for her project?
"How the Palm Tree Grows"
"The Life Cycle of a Palm Tree"
"A Day in the Life of a Palm Tree"
"From Seed to Tree; The Story of a Palm Tree"
"A Day in the Life of a Palm Tree"
The worst choice for a title would be "A Day in the Life of a Palm Tree" because it is only is focused on one day of the tree's life rather than the entirety. The other names encapsulate what the project is about and focus on the lifespan on the tree. Carol has to make a model of the palm tree's life, so the title needs to include all parts from life to death.
Example Question #6 : Diverse Life Cycles Of Organisms
Which photograph models an organism that is in the middle of a change during their life cycle?
Models of organisms' life cycles can be made in numerous ways, and one is through a photograph. The image showing a tadpole as it develops legs and is losing its tail. As it matures, it will become a froglet and finally an adult frog. Frogs move through multiple stages before reaching their final adult form.
Example Question #1 : Describe Unique Organisms' Life Cycles And Similarities
What does the term organism mean? Example: Each organism has a unique life cycle.
An internal body part needed for life
An individual plant or animal
A group of different species living together
An unknown creature
An individual plant or animal
The term organism refers to an individual plant or animal. An organism is a living thing. An organism can be as simple as a single-celled life form or as complex as a human. Each organism does have a unique life cycle or stages that it travels through from birth to death.
Example Question #2 : Describe Unique Organisms' Life Cycles And Similarities
How is the life cycle of a duck different than the life cycle of a human?
Ducks live to adulthood, and humans do not live to adulthood.
Humans hatch from eggs, and ducks do not hatch from an egg.
Humans live to adulthood, and ducks do not live to adulthood.
Baby ducks hatch from eggs, and humans do not hatch from an egg.
Baby ducks hatch from eggs, and humans do not hatch from an egg.
There are both similarities and differences between the life cycle of a duck and a human. Both humans and ducks are born, go through a juvenile stage, move into adulthood, and then have offspring of their own. There is a difference to the start of their life cycles though, humans have live births, and ducks hatch from an egg.
Example Question #3 : Describe Unique Organisms' Life Cycles And Similarities
Though plants and animals have diverse and unique life cycles, there are some similarities between them.
True
False
True
The statement presented is accurate. The life cycles of plants and animals are diverse and different, but there are similarities to be found. The life cycle of plants and animals is the stages they follow from birth to death.
Example Question #4 : Describe Unique Organisms' Life Cycles And Similarities
Describe a unique characteristic of the butterfly's life cycle.
The butterfly pollinates flowers.
The butterfly undergoes a metamorphosis.
The butterfly becomes an adult.
The butterfly begins life as an egg.
The butterfly undergoes a metamorphosis.
A unique characteristic of the butterfly is that it undergoes a metamorphosis. The butterfly begins as an egg, then a larva (a caterpillar), a pupa in the cocoon, and finally will emerge as a butterfly. Metamorphosis is the change of shape or form, a transformation.
Example Question #5 : Describe Unique Organisms' Life Cycles And Similarities
What is a similarity between a snake's life cycle and a butterfly's life cycle?
They both go through metamorphosis.
They both grow legs.
They both have an adult phase.
They both build cocoons.
They both have an adult phase.
At first glance, a snake and butterfly don't seem to have a lot in common, but they do have some similarities. One example is that they both have an adult phase. The path to get to adulthood may be different for a snake and butterfly, but eventually, they both reach the final stage and become adults.
Example Question #1 : Describe Unique Organisms' Life Cycles And Similarities
What is a similarity between a frog's life cycle and a butterfly's life cycle?
They both build a cocoon.
They both grow wings.
They both grow long tails.
They both start as eggs.
They both start as eggs.
At first glance, a frog and butterfly don't seem to have a lot in common, but they do have some similarities. One example is that they both start as eggs. The path to get to adulthood may be different for a snake and butterfly, but in the beginning, they are both just eggs. Their lives take different paths after the eggs hatch, but this is a similarity between the two animals.
