BIOL 1902 FINAL EXAM (WITH COMPLETE SOLUTIONS)
Mobility and Adaptations

1. What does "mobility" refer to in animal adaptation?

 A) Ability to climb steep surfaces

 B) Ability to move freely through snow

 C) Ability to swim through icy waters

 D) Ability to leap across rivers
Answer: B) Ability to move freely through snow
Rationale: Mobility, in this context, refers to how animals adapt to moving efficiently through
snow-covered terrains.



2. What is a unique physical adaptation of moose to navigate snowy environments?

 A) Webbed feet for swimming

 B) Long legs up to 2 meters high

 C) Fur that repels snow

 D) Antlers to clear pathways
Answer: B) Long legs up to 2 meters high
Rationale: Moose have long legs that help them step over deep snow, ensuring efficient
movement.



3. How do snowshoe hares adapt to snowy environments?

 A) White fur for camouflage

 B) Sharp claws to dig through snow

 C) Large hind feet to walk above the snow

 D) Hollow bones to reduce weight
Answer: C) Large hind feet to walk above the snow
Rationale: Snowshoe hares have large hind feet that distribute their weight and prevent them
from sinking into the snow.

4. Which animal is a northern weasel with large hind feet adapted for snow?

 A) Mink

 B) Marten

 C) Fisher

 D) Wolverine
Answer: C) Fisher
Rationale: Fisher's large hind feet aid in movement across snow-covered terrains.



5. What adaptation helps the northern grouse move easily in snow?

 A) Feathers on its feet act like snowshoes

 B) Longer legs for stepping over snow

 C) Sharp talons for gripping icy surfaces

 D) Lightweight body for floating on snow
Answer: A) Feathers on its feet act like snowshoes
Rationale: The feathers on the feet of northern grouse increase surface area, enabling
movement over snow.



Behavioral Adaptations in Winter

6. What behavioral adaptation do white-tailed deer exhibit during heavy snowfalls?

 A) Hibernate in caves

 B) Move to a sheltered area called a yard

 C) Dig through snow for food

 D) Travel south to avoid snow
Answer: B) Move to a sheltered area called a yard
Rationale: White-tailed deer gather in areas with less snow, called "yards," to conserve energy
and access food.



7. What is a "browse line" in relation to white-tailed deer?

,ESTUDYR


 A) The highest point a deer can reach to feed on a tree

 B) A trail created by deer movement in the snow

 C) A behavioral signal for gathering in herds

 D) A natural marker for deer territories
Answer: A) The highest point a deer can reach to feed on a tree
Rationale: Deer feed on tree branches within their reach, creating a visible browse line.



8. How do otters and minks move across snow?

 A) Leap and bound through the snow

 B) Toboggan on their stomachs

 C) Glide across icy surfaces using their tails

 D) Use their paws to dig tunnels
Answer: B) Toboggan on their stomachs
Rationale: Otters and minks use their short legs and stomachs to slide across snowy surfaces
efficiently.



Migration in Animals

9. Where do monarch butterflies migrate during the winter?

 A) Canada

 B) Southern United States

 C) Mexico

 D) Northern Africa
Answer: C) Mexico
Rationale: Monarch butterflies migrate to Mexico to escape cold winter conditions.



10. Which insect migrates to the Cape Cod area over winter?

 A) Ladybugs

 B) Locusts

, ESTUDYR


 C) Green darner dragonfly

 D) Fireflies
Answer: C) Green darner dragonfly
Rationale: The green darner is one of the few dragonflies known to migrate.



Adaptations in Birds

11. What makes the Arctic tern unique in terms of migration?

 A) It travels over 20,000 km in a year

 B) It migrates solely during the daytime

 C) It navigates exclusively using Earth's magnetic field

 D) It remains in the Arctic during winter
Answer: A) It travels over 20,000 km in a year
Rationale: The Arctic tern's migratory journey is among the longest in the animal kingdom.



12. What physical adaptation allows semipalmated sandpipers to prepare for migration?

 A) Faster flight speed

 B) Doubling body weight in 10 days

 C) Long legs for running

 D) Specialized wing feathers
Answer: B) Doubling body weight in 10 days
Rationale: Sandpipers store energy by increasing their body weight rapidly before migration.



Navigation in Migration

13. What visual cues do birds use for navigation during migration?

 A) Ocean, sun, and mountains

 B) Air pressure and temperature gradients

 C) Star clusters and constellations
