Whitesel Life Science Test Week 14

From the characteristics above, which question can be asked to find out about characteristics of monarch butterflies that are instincts?

• Why do monarch butterflies migrate?
• What stages are in the monarch butterfly life cycle?
• What colors are monarch butterflies?
• How does a monarch butterfly defend itself from predators?

Eelgrass is a major source of food for birds and turtles in an estuary. What will most likely happen to the bird and turtle populations if people remove the eelgrass to build a bridge?

• The turtle population will increase, but the bird population will decrease.
• The bird population and the turtle population will increase.
• The bird population will increase but the turtle population will decrease.
• Both the bird population and the turtle population will decrease.

In a lake ecosystem, how would people catching too many minnows most likely affect the minnows' predators?

• The predators would lose much of their food source.
• The predators would move to a new lake.
• The predators would reproduce more.
• The predators would not be affected.

Orcas living in the Pacific Ocean hunt a variety of sea animals including sea otters. The sea otters eat a diet of sea urchins. Sea urchins eat seaweed called kelp. What would most likely happen to the other organisms if there was an increase in the orca population?

• kelp (decrease) → sea urchin (increase) → sea otter (decrease) → orca (increase)
• kelp (increase) → sea urchin (increase) → sea otter (decrease) → orca (increase)
• kelp (decrease) → sea urchin (decrease) → sea otter (decrease) → orca (increase)
• kelp (decrease) → sea urchin (decrease) → sea otter (decrease) → orca (decrease)

Rabbits eat field grains. Great horned owls eat rabbits. Bacteria break down all these organisms when they die. Which will most likely cause a decrease in the number of great horned owls?

• an increase in the number of field grain plants
• a decrease in the number of rabbits
• a decrease in the number of bacteria
• an increase in the number of rabbits

Which is an acquired trait rather than an inherited trait?

• Eye color
• Skin Color
• Hair color
• Unnatural hair color (ex. pink, blue)

Which is an example of an acquired trait?

• shape of face
• hair color
• scar
• tongue rolling

Which characteristic most likely could not be inherited by the offspring?

• Green leaves
• 25 cm stem
• Yellow center
• Red petals

Whales (orcas) living in the Pacific Ocean hunt a variety of sea animals including sea otters. The sea otters eat a diet of clams and sea urchins. Sea urchins eat seaweed called kelp. Which model represents the relationship of where the organisms get food and energy in the Pacific Ocean?

• kelp → sea urchins → sea otters → orcas
• sea urchins → kelp → orcas → sea otters
• kelp → sea urchins → orcas → sea otters
• orcas → sea otters → sea urchins → kelp

A mother rabbit has a litter. One of the babies is born with one long ear and one short ear. What most likely caused this one rabbit to be born with one short ear?

• The mother rabbit became sick before she gave birth.
• The mother rabbit had previously lost an ear in an accident.
• A mutation occurred during the development of this one rabbit.
• This one rabbit received less nutrition than the other rabbits before it was born.
