stamen
ovary
pistil
petal

water
Choose TWO things that can scatter the seeds of different plants.
wind
rocks
water
sunlight
soil
Mosses produce _________ in order to reproduce.
flowers
spores
cones
seeds
A spore is different from a seed because it is
much smaller in size.
scattered by wind and water.
unable to create offspring.
all of the above
When a male and female structure combine, it is called
circulation
fertilization
multiplying
sprouting
Pine, fir, and spruce trees do not have flowers with pistils and stamens, so they reproduce using
spores and petals
seeds that float on water
seeds that have tiny hooks
male cones and female cones
Kellan finds some seeds from a maple tree like the ones shown in the picture. How are these seeds scattered? Use evidence from the picture to make your claim.
The seeds have tiny hooks for clinging to animal fur.
The seeds have a hollow inside for floating on water.
The seeds have “wings” for getting carried away by wind.
The seeds have “parachute” structures for floating in the air.
What do seeds and spores have in common?
They both are used by mosses to reproduce
They both are only transported by the wind.
They both can eventually grow into new plants.
They both come from conifer trees.
Choose THREE reasons that it is important for seeds to be able to scatter.
so they can grow in a new area that may better sunlight
so they can grow in a new area that may have more water
so they can grow in a new area with more nutrients
so that animals and insects can eat them
Choose ALL things the digestive system of an animal does.
mashes food into tiny pieces

Anthony has a pet turtle. He gives the turtle some food. The turtle sees and smells the food, and then eats it. After the turtle sees and smells the food, where does the message go?
along nerves to the legs
to the turtle’s sense receptors (like nose and eyes)
along nerves to the turtle’s brain
to the chewing muscles of the mouth

Both have sense receptors to detect sound.
Both have sense receptors to detect light.
Both have sense receptors to detect smell.
You see this sunflower in a field. What is the correct path of light that makes it possible for you to see the flower?

The light from your eye bounces off the flower and then reflects into the sun.
The light from the sun bounces off your eye and then reflects into your flower.
The light from the sun bounces off the flower and then reflects the colors into your eye.
Engineers help solve problems. They design the hearing aid shown in the picture. Engineers follow steps when they solve problems. Which list shows the correct order of steps that engineers follow to solve a problem?
identify the problem -> test the solution -> improve the solution -> design a solution
design a solution -> test the solution -> improve the solution -> identify the problem
identify the problem -> design a solution -> test the solution -> improve the solution
design a solution -> identify the problem -> test the solution -> improve the solution
Which type of joint, like the one in human hips, rotates?

Your garden attracts many different kinds of butterflies. You observe a butterfly use its feet to taste nectar on the flower as shown in the picture. Which of the following BEST models how the butterfly senses nectar in the flower?
The feet are a stimulus and the taste is the response.
The nectar is a sense receptor that responds to stimuli.
The feet have sense receptors that detect the stimulus, which is taste.
The nectar is a sense organ that can detect the stimulus, which is taste.
Nathan is visiting the zoo. He sees a mother zebra and her offspring. Which BEST describes memory in the two zebras?
The mother and the offspring have similar memories because they are related to each other.
The mother and the offspring have weak memories because they do not have to hunt for food.
The mother has stronger memories because she has repeated behaviors more times than the offspring.
The offspring has stronger memories because he has repeated behaviors fewer times than the mother.
