The giant tortoise can live up to 175 years.
The giant tortoise can go a year without food.
A giant tortoise sleeps up to 16 hrs. a day.
The Galapagos Islands are special because of where they are and what lives there. They are in the middle of the colliding warm and cold water currents. They are home to marine iguanas, the only sea species of iguana in the world. The waved albatross needs the Galapagos Islands to have a place to breed.Sea lions also migrated there. This is the home to penguins.

Guppy Simulation
1) To attract mates.
2) Guppy or Millions fish
scientific name: Poecilia Reticulate
from Brazil
size: 1.9"
metallic silver in color, blackish blue tail and fins

size: 1.9"
metallic silver in color, blackish blue tail and fins
3) Tigerfish
scientific name: Hoplias Malabrsacus
up to 24"
from Trinidad
sandy brown in color
scientific name: Hoplias Malabrsacus
up to 24"
from Trinidad
sandy brown in color
4) The size of the body of water and the size of the predator fish.
5) John Endler is a biologist that studied guppies in Trinidad.
6) Pool1: Very bright with large spots
Pool2: Medium coloration with medium spots
Pool3: Very drab in color
Pool2: Medium coloration with medium spots
Pool3: Very drab in color
7) Higher in the stream there are few predators so that they are able to be colorful and the lower you get the drabber you get.
% of Brightest Guppies | % of Bright Guppies (10 generations) | % of Drab Guppies (10 generations) | % of Drabbest Guppies (10 generations) | |
Trial 1 Guppy: Even Mix | 61% | 29% | 10% | 0% |
Trial 2 Guppy: Even Mix | 13% | 77% | 11% | 0% |
Trial 3 Guppy: Even Mix | 3% | 4% | 6% | 87% |
Trial 4 Guppy: Mostly Bright | 65% | 24% | 7% | 4% |
Trial 5 Guppy: Mostly Drab | 0% | 0% | 0% | 100% |
8) They eat the easiest to see fish and so the fish become drabber to survive.
9) 1:My hypothesis was correct, less predators=brighter colors.
2: No, my hypothesis was wring because the brighter guppies survived.
3: My hyppothesis was correct because the drabbest survived and the brightest died out.
4: My hypothesis was correct there were few predators and the brightest survived.
5: My hypothesis was correct, with lots of predators, only the drabbest guppies survived.
2: No, my hypothesis was wring because the brighter guppies survived.
3: My hyppothesis was correct because the drabbest survived and the brightest died out.
4: My hypothesis was correct there were few predators and the brightest survived.
5: My hypothesis was correct, with lots of predators, only the drabbest guppies survived.
10) The males are conspicuous to predators and easier to spot by everyone.
11) There are fewer predators higher in the stream allowing the males to be brighter in coloration.
12) They would die out because the brighter guppies get mates.
13) They would die because the predators can see him better.

Biodiversity
1) Okay, say that you switch to recycling, then the amount of waste dumped in the ocean and landfills of the world.
2) If an species with healing properties that we have not yet utilized could die and then we would not know what we could have healed with those properties or an animal like bees could stop moving pollen and the plants and animals that feed on them will die.
3) If we conserve the number of different species on Earth, then we could learn of a new cure for say cancer or AIDS and we would have a larger food source.
