Example Question #1 : Animal Effects On Plant Pollination
Which answer choice correctly uses the term mimic?
Marge has to mimic the garlic into tiny pieces for the spaghetti recipe.
She loves to mimic her brother and do the opposite of him.
To mimic a butterfly pollinating flowers, I need to have wings and fly around.
When I mimic my flowers, I always make sure to space them out and give them water.
To mimic a butterfly pollinating flowers, I need to have wings and fly around.
To mimic means to copy, impersonate, or imitate something or someone. "To mimic a butterfly pollinating flowers, I need to have wings and fly around." is the correct answer choice because it uses the word correctly. In the sentence, the author is trying to copy a butterfly pollinating flowers and would need wings to accomplish this. The other sentences use mimic incorrectly.
Example Question #1 : Animal Effects On Plant Pollination
One way that seeds travel from place to place is through animal poo! How does animal poo help to transport seeds and allow new plants to grow?
The seeds pass to the poo and new plants can grow in that spot.
Animal's poo out the seeds which then go deep underground to be dug up and planted later.
The seeds start to form new plants in the animal, so they poo out the tree or flower.
Animal poo does not help transport seeds to new locations or help plants to grow.
The seeds pass to the poo and new plants can grow in that spot.
Animals that spread seed through their excrement (or poo) have first to eat fruits, vegetables, or plants with seeds. Bears, bats, monkeys, and turtles would be the types of animals that would spread seeds through their poo. As they move around their environment, the seeds exit their digestive system and land in a new place. When this happens, the seeds are relocated and may form new plants where they land.
Example Question #2 : Animal Effects On Plant Pollination
The image below is of a spiky seedpod often nicknamed a "hitchhiker" because it attached to clothing or an animal's fur and is dispersed through the environment.
Wanda is building a model of an animal that would help disperse these spiky seeds. Which animal should she design her model after to mimic the same effect?
Bear
Catfish
Bald Eagle
Alligator
Bear
If a seed is a hitchhiker, it needs to attach to something to be carried around. If creating a model that mimics an animal that helps with this process, it must have the necessary features. Fish live underwater and are unlikely to come across these seeds. Scales are slick, so the seed would not attach as well to an alligator. Bald eagles primarily live in trees or high nests and eat meat. Fur or hair would be a more critical feature because it gives the seed something to get stuck to so it can be carried around so a bear would be the best animal to mimic.
Example Question #4 : Develop A Model Mimicking An Animal Dispersing Seeds
Animals cannot help disperse seeds unless they eat them.
False
True
False
The statement in the question is false. There are more ways animals can disperse seeds than just eating them. Examples of animals dispersing seeds without eating them include seeds getting stuck to an animal's fur and carried around, animals may bury seeds and plant new trees accidentally, or pollinators carry pollen from flower to flower. Animals do spread seeds by eating them and then excreting them in a new location in their poo, but it isn't the only way.
Example Question #11 : Animal Effects On Plant Pollination
What is pollination? Example: Pollination is an important part of the life cycle.
When a adult animal teaches a baby animal something
When caterpillars emerge from their cocoon
Littering or releasing chemicals into the environment
The transfer of pollen to create new plants
The transfer of pollen to create new plants
Pollination is the transfer of pollen to new plants for fertilization. Bees, hummingbirds, and butterflies are just a few animals that help the pollination process. The animals go from plant to plant, spreading the pollen.
Example Question #12 : Animal Effects On Plant Pollination
Miranda's teacher asked them to draw a model of an animal pollinating plants. Which of the following should she draw?
Bee
Butterfly
All of the animals are pollinators
Bat
All of the animals are pollinators
If Miranda is drawing an animal that pollinates plants, she could draw any from the list; they are all pollinators! Bats, bees, and butterflies all move from flower to flower, spreading pollen to help fertilize plants so new ones can grow.
Example Question #13 : Animal Effects On Plant Pollination
Hummingbirds pollinate tube-shaped flowers that have nectar and pollen. Their beak picks up pollen from one flower while they feed, and it is dropped into another flower when they move to the next plant to eat.
If humans wanted to use something that mimicked a hummingbird to pollinate their flowers, which item would be best?
Your hand
A cup
A spoon
A straw
A straw
The best tool to use for mimicking a hummingbird's beak would be a straw. It is thin and can fit inside the tubular flowers to collect pollen or nectar. It could be moved easily from plant to plant for fertilization.
Example Question #4 : Develop A Model Mimicking An Animal Pollinating Plants
Michael is creating a model of an animal that pollinates plants. He knows that while the animal stops at a flower to eat, it gets covered in pollen. The pollen sticks to the animal as it flies to the next flower. There the powder is rubbed into the flower, and new material is picked up to be spread.
Which material would be best for building his animal to transport pollen?
Tinfoil
Paper
Felt
Plastic wrap
Felt
Michael should select felt as the material to make his animal. Felt is soft, textured, and made of cloth so the pollen dust would stick to the fabric. Plastic wrap, tinfoil, and paper are all flat and slippery, so the pollen would not stick so it can be carried around.
Example Question #14 : Animal Effects On Plant Pollination
Heidi is making a model of a bumblebee for her pollinator project. She knows the bee moves from plant to plant spreading pollen dust, so what it is made of is very important. The pollen has to stick to the body so it can be flown around.
Which item would be right to use to mimic the body of a bumblebee?
Magnet
Cottonball
Golf ball
Rock
Cottonball
The body of a bumblebee gets covered in pollen as it moves from flower to flower. The dust sticks to their soft, fuzzy hair. A cotton ball would be the best choice for a material that mimics the body of a bee. It is also fuzzy and soft, so dust will stick to it. A golf ball, rock, and magnet are smooth, and pollen dust would be less likely to hold.
Example Question #31 : Life Science
What does the term mimic mean? Example: I can use a straw to mimic the beak of a hummingbird.
A type of plant used to season food
Extremely small or tiny
The theatrical technique of moving silently
Imitate, copy, or impersonate
Imitate, copy, or impersonate
To mimic means to copy, impersonate, or imitate something or someone. If I want to mimic the behavior of a hummingbird and model a tool that is similar to its beak, the straw would be a good fit. It is a similar shape, size, and has the same function. I could copy or mimic a hummingbird's actions and collect liquid.
