Male widow (Euplectus progne) have very long tail feathers. What evidence would support the claim that these tails are used by the birds to attract mates and lead to reproductive success?

• Male widow birds each possess twelve tail feathers

• In every generation, the small number of males with the longest tail feathers produce the greatest number of offspring

• The males with the longest tail feathers are the easier to locate in their habitat than those with shorter tail feathers.

• Even though the wingspan of males does not exceed 15 centimeters, some males have tail feathers 50 centimeters long

Why are fruits considered to be an advantage for plant reproduction?

• After the fruit is eaten, the seed can be deposited in a new location in the droppings of an animal

• The fruit will eventually fall to the ground and split apart, releasing pollen to cross-pollinate other flowers in the area.

• The fruit attracts insects to the tree where they can feed on it to release the seed.

• The fruit can be carried to other plants and allow for cross-fertilization.

The Articum lappa plant produces prickly burrs that grow on the ends of the stems. These burrs can easily catch on the fur of animals. This plant structure most likely benefits the plant in which of the following ways:

• Keeps the plant warmer

• Attracts animals to come near the plant

• Increases the plant's water absorption

___________ factors are any factor, whether abiotic or biotic, that influences an organism.

• Tropical

• Non Tropical

• Environmental

• Multiplication

• Several seeds from one single parent plant are planted under a variety of conditions and found to grow at similar rates

• Several seeds from one single parent plant are planted under a variety of conditions and found to grow at different rates.

Emperor penguins spend their entire lives in Antarctica, where temperatures can drop as low as -60°C. After a female has laid an egg, she hunts for food in the ocean and leaves the egg in the care of the male penguin. While the female is hunting, the males of the group balance the egg on their feet and surround it with feathered skin. How does this behavior affect the probability of the egg hatching?

• The males fight off predators while holding the egg.

• The female gathers food for the males while they watch the egg hatch.

• The eggs can be huddled together in a large nest until they hatch.

• The males keep the egg warm until the egg is ready to hatch.
