Nocturnal Being That Survives on Blood

Darwin's Natural Selection Worksheet Name "ead the following situations below and identify the 5 points of Darwin's natural selection. There are 2 types of worms: worms that eat at night (nocturnal) and worms that eat during the day (diurnal). The birds eat during the day and seem to be eating ONLY the diurnal worms. The nocturnal worms are in their burrows during this time. Each spring when the worms reproduce, they have about 500 babies but only 100 of these 500 ever become old enough to reproduce. a.

The temperatures are dropping rapidly and the bears must be kept warm, or they will freeze to death. Many of the bears have had ~2 cubs each but due to the extreme temperatures, many mothers only have one cub left. L. What bear will natural selection select AGAINST? Thin coats FOR?

The fast birds can reach up to 40 kilometres an hour. Dingo love to eat emu, and they can reach speeds of up to 35-40 kilometres per hour. A flock of emu will lay-10 eggs (each mother only lays 1), but many rodents break into the eggs and eat the fetus before they hatch. a.

Certain kinds of worms that live in the Arctic   also make antifreeze proteins that help them live in icy water.   | | | | ✓ | | Ants are the correct size and weight needed to open the flowers for the peony plant. The peony plant provides food for the ant and the ant fertilizes the peony's flowers.   | | | ✓ | | | A kit fox lives in the desert and has large ears with greater surface area that keep the fox from getting overheated. The red fox lives in the forest and has a red coat that keeps it camouflaged.   | | ✓ | | | | Hummingbirds have a beak just the right length to reach the nectar in a cardinal flower and as they feed their foreheads bump into the pollen structure. Cardinal flowers are red which hummingbirds can see but bees can't. Cardinal flower's pollen structure is just the right length for the hummingbird to pick up pollen as it feeds.   | | | ✓ | | | The Galápagos tortoises share a common ancestor, but have necks of different lengths to best reach the food they feed on in their environment. | | ✓ | | | | Whales, sharks, and penguins all have streamlined bodies and fins/flippers for moving in water even though they belong in different classes of animals (mammals,   fish, and birds). | ✓ | | | | | The Galápagos tortoises share a common ancestor, but have necks of different lengths to best reach the food they feed on in their environment. | | ✓ | | | **Note:** The last two rows seem to be duplicates.
