Example Question #8 : Plant And Animal Survival

How are plants useful to humans besides food?

Possible Answers:

Humans cannot use plants for anything besides food.

Humans can mimic plants for survival.

Humans can use plants to tell the future.

Correct answer:

Humans can mimic plants for survival.

Example Question #9 : Plant And Animal Survival

The foundation of a house keeps it stable and in place. What part of the plant does the same?

Possible Answers:

Leaves

Roots

Flower

Correct answer:

Roots

Explanation:

The roots of a plant keep it stable and in place. Humans have mimicked or copied this survival strategy and used it to keep our houses in place and stable. Without strong roots or a strong foundation the plant or home would fall over.

Example Question #10 : Plant And Animal Survival

There are no parts of a plant that are similar to something a human uses.

Possible Answers:

False

True

Correct answer:

False

Explanation:

There are many parts of a plant that humans use to solve their own problems and make new items. Rafts, helmets, fencing, and more are all modeled after plant parts.

Example Question #1 : Solve A Human Problem Mimicking How Animals Survive

Motorcycle riders wear special clothing to protect their skin and bones if they crash. This is similar to the _________ on reptiles.

Possible Answers:

legs

gills

scales

Example Question #2 : Solve A Human Problem Mimicking How Animals Survive

The ________ of an animal helps keep it upright and stable. Humans mimicked this solution when we made a tripod.

Possible Answers:

arms

tail

brain

Correct answer:

tail

Explanation:

The tail of many animals keeps it upright and stable when standing on two legs. The tail acts as a third limb to keep it from falling over. The same thing happens with a tripod for a camera or phone. The three legs keep it steady.

Example Question #3 : Solve A Human Problem Mimicking How Animals Survive

Porcupines raise sharp quills on their backs when a predator approaches. Humans can _________ this function to help us survive as well.

Possible Answers:

hate

mimic

approve

Correct answer:

mimic

Explanation:

Humans can mimic or copy the ways animals survive to help us as well. Porcupines raise their quills when a predator approaches to scare them away or even stick them if they get too close. Humans use sharp strips on the ground to pop car tires and warn drivers to stop. We are mimicking animals to solve problems.

Example Question #1 : Solve A Human Problem Mimicking How Animals Survive

Humans have alarm systems with cameras, motion detectors, and lights to keep intruders out of our homes. What features of animals are we mimicking to solve our problem?

Possible Answers:

Ears and eyes

Arms and legs

Noses and feet

Correct answer:

Ears and eyes

Explanation:

Humans are mimicking animals' ears and eyes to help us keep our own houses safe. Many animals have excellent hearing and vision, and this keeps them safe from predators, especially at night. Humans cannot see in the dark, so motion detectors and lights help us to see cameras record what happens so we can watch it. The alarm system acts like eyes and ears to keep us safe.
