Science Unit 8 adaptations and inherited traits

What type of adaptation would be idea for an aquatic environment?

• Oil Coated Feathers

• Suppering tunneling ability

• short soft fur

• migrates by flying

The shells of sea turtles are flatter then the shells of land turtles.

Sea turtles are different from land turtles because

sea turtles cannot pull their head or limbs into their shell to protect them from predators.

Instead the head, shell shape, and flippers of sea turtles help them escape from predators mainly allowing them to_.

• Dig deep holes

  for their eggs.

• Swim and

  dive easily.

• Blend into their

  surroundings.

• Hold their breath for several minutes.

A snowshoe hare has many structural adaptations that help it survive in its environment.

Which adaptation of the snoeshoe hare provides warmth and camouflage in its cold and snowy environment?

• long, flexible ears

• large, brown eyes

• thick, white fur

• wide, strong feet

Which two traits best help a cactus conserve water in the dry conditions of a West Texas desert ecosystem

• The spines shade the plants from the suns heat and waxy stems

• large flowers help conserve water and sweet fruit

• sweet fruit conserves water and sharp spines

• waxy stems conserve waterand large flowers

A group of students make observations about fish in a small aquarium.

Which observations are about inherited traits?

• Observation 1,3, and 6

• Observation 1,2, and 4

• Observation 2,3, and 5

• Observation 2,5, and 6

Fox squirrels live in the trees of city parks through out Texas. Each spring they build nests of twigs and leaves in the tops of the trees. Fox squirrels are often found near park benches, waiting to be fed by visitors.

For fox squirrels, which of these is a learned behavior?

• Having sharp claws

• Having a long bushy tale

• building a nest each spring

• taking food from people

A snowshoe hare has many structural adaptations that help it survive in its environment.

Which adaptation of the snow shoe hare provides warmth and camouflage in its cold and snowy environment

• Large, brown eyes

• thick, white fur

• long, flexible ears

• wide, strong feet

Which two traits best help a cactus reserve water in the dry conditions of a West Texas desert ecosystem.

• The spines shade the plants from the sun's heat and waxy stems

• Large flowers and sweet fruit conserves water

• Sweet fruit and sharp spines conserves water

• Waxy stems and large flowers conserves water

For a science assignment a student was asked to observe some organisms and then make a table to classify the organisms traits as inherited or learned. The student's table is shown below.

How many of these observations describe learned behavior and how many describe inherited traits.

• 3 learned behaviors, 5 inherited traits

• 1 learned behavior, 7 inherited traits

• 4 learned behaviors, 4 inherited traits

• 2 learned behaviors, 6 inherited traits.

Some traits of living organisms are inherited, while some behaviors must be learned. Which statement related to inherited traits or learned behaviors is not correct?

• The ability of a figure skater to spin on ice is related to both inherited traits and learned behaviors

• The ability of lions to use camouflage to hide in grassy fields is an inherited trait only

• The number and type of legs a cricket has is an inherited trait only

• The behavior of a dog guiding a blind person on a walk through a neighborhood is an inherited trait only.
