Leopard seals are animals adapted to survive in the freezing conditions of Antarctica. Individual seals vary in their different traits, such as the number of spots on their coats, the thickness of their layer of blubber, and the shape of their heads. Which one of these traits would have the greatest impact of a leopard seal surviving in a cold environment?
number of teeth
thickness of their blubber layer
shape of their head
number of spots on their coats
In a given population of plants there is variation in the time of day when flowers open. Those individual plants with flowers that open at night would be more likely to pass on this trait in an environment dominated by what?
nocturnal pollinators
moist soil
diurnal pollinators
grazing animals
Some plants have developed a thick, waxy coating that helps prevent the loss of water. In order for plants to develop this thick, waxy coating over many generations, what must be true?
The plants must have variation in the amount of waxy coating
The plants must be able to absorb water directly from the air.
The plants must live in an area with heavy rainfall.
The plants must produce wax that animals are able to eat.
This illustration provides information on four variations in the size and shape of antlers in a population of moose. In order to grow antlers, a male moose must use a large amount of the energy it gets from food. In an environment where food resources are limited, which type of antler would be more common?
A
B
C
D
The data provide evidence that best supports the claim that these chickens are being bred for which characteristic?
Fewer white feathers
Larger bodies
Shorter beaks
More tail feathers
Greyhounds are dogs with long, powerful legs and slim bodies that make them very fast runners. Which of the following best describes how humans were able to engineer this breed of dog?
For many generations, these dogs were allowed to run freely in large, open fields.
Dogs that were slower than others were given exercise and trained to run fast.
Over many years, all the dogs were fed diets high in protein and vitamins.
In every generation, only those dogs with the desired traits were allowed to reproduce.
