Example Questions

Example Question #1 : Describe Unique Organisms' Life Cycles And Similarities

What does the term organism mean? Example: Each organism has a unique life cycle.

Possible Answers:

A group of different species living together

An individual plant or animal

An unknown creature

An internal body part needed for life

Correct answer:

An individual plant or animal

Explanation:

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 #1 : Describe Unique Organisms' Life Cycles And Similarities

How is the life cycle of a duck different than the life cycle of a human?

Possible Answers:

Humans live to adulthood, and ducks do not live to adulthood.

Humans hatch from eggs, and ducks do not hatch from an egg.

Baby ducks hatch from eggs, and humans do not hatch from an egg.

Ducks live to adulthood, and humans do not live to adulthood.

Correct answer:

Baby ducks hatch from eggs, and humans do not hatch from an egg.

Explanation:

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 #2 : Describe Unique Organisms' Life Cycles And Similarities

Though plants and animals have diverse and unique life cycles, there are some similarities between them.

Possible Answers:

False

True

Correct answer:

True

Explanation:

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 #3 : Describe Unique Organisms' Life Cycles And Similarities

Describe a unique characteristic of the butterfly's life cycle.

Possible Answers:

The butterfly undergoes a metamorphosis.

The butterfly begins life as an egg.

The butterfly pollinates flowers.

The butterfly becomes an adult.

Correct answer:

The butterfly undergoes a metamorphosis.

Explanation:

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 #1 : Describe Unique Organisms' Life Cycles And Similarities

What is a similarity between a snake's life cycle and a butterfly's life cycle?

Possible Answers:

They both build cocoons.

They both have an adult phase.

They both grow legs.

They both go through metamorphosis.

Correct answer:

They both have an adult phase.

Explanation:

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 #4 : Describe Unique Organisms' Life Cycles And Similarities

What is a similarity between a frog's life cycle and a butterfly's life cycle?

Possible Answers:

They both grow wings.

They both build a cocoon.

They both start as eggs.

They both grow long tails.

Correct answer:

They both start as eggs.

Explanation:

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.

Example Question #5 : Describe Unique Organisms' Life Cycles And Similarities

Describe a unique characteristic of the frog's life cycle.

Possible Answers:

A frog starts as an egg and then morphs directly into an adult form.

A frog starts with a tail, then grows legs, and finally, the tail shrinks until it is gone.

Frogs do not have any unique characteristics in their life cycle.

A frog starts with a tail, then grows wings, and finally, the tail shrinks until it is gone.

Correct answer:

A frog starts with a tail, then grows legs, and finally, the tail shrinks until it is gone.

Explanation:

A unique characteristic of the frog's life cycle is its loss of tail and the growth of legs! A tadpole has a tail, and slowly legs grow (two at a time) as the tail shrinks. For quite a while, the frog has a small tail and four legs. Eventually, the tail shrinks until it is gone, and the frog reaches its adult stage.

Example Question #6 : Describe Unique Organisms' Life Cycles And Similarities

Many animals have unique life cycles.

Possible Answers:

False

True

Correct answer:

True

Explanation:

Each organism is unique because they are all different. No two organisms are identical. Each offspring inherits characteristics from their parents, which gives them their make-up. Different organisms move through different life cycles, which put them at different stages. Many animals have different ways of caring for their young, gathering food, or life expectancies. Plants come in varieties of sizes, colors, and shapes. Each organism is unique.

 

Example Question #6 : Describe Unique Organisms' Life Cycles And Similarities

In the photo below, something unique is taking place. A caterpillar will build a cocoon and stay inside for seven to ten days. While inside it is called a(n) _______. When it emerges, it is a butterfly!

Cocoon, Butterfly, Insect, Nature

Possible Answers:

Tadpole

Pupa

Nymph

Egg

Correct answer:

Pupa

Explanation:

The caterpillar forms itself into a pupa or chrysalis, and it remains inside as it transforms into a butterfly. The pupa stage may last a few weeks to several months, depending on the species. The case around the pupa hardens to protect the caterpillar as it grows into the butterfly.

Example Question #2 : Describe Unique Organisms' Life Cycles And Similarities

What is a life cycle? Example: During a frog's life cycle, it changes shape and form.

Possible Answers:

The circle that animals travel in when they migrate.

A type of bicycle that has one wheel instead of two.

The cycle that water travels from the ground to the atmosphere.

The series of changes in the life of an organism.

Correct answer:

The series of changes in the life of an organism.

Explanation:

The life cycle of plant or animal (humans included) is the series of changes that the organism undergoes in its life. It starts at reproduction and moves through the different stages of life until it ends and begins over with the offspring. Different animals have different life cycles, and they are not all the same.
