Ehh, i dono where to do my revision, so i'll just do it in my blog.
hahas, i'm abit bo liao >< and cause cause i everyday come blog than also can revise mah.
See this method is smart right?
haha jkjk let's start wif my revision !

Science Revision on Adaptation:D
Land Habitats
Coping with temperature
(structural adaptation)
Polar bear lives in arctic cold regions. It has thick fur, a layer of insulating fat under the skin to keep the animal warm and a layer of air close to the skin to prevent heart loss to the surrounding.

Musk ox, Arctic fox and Snow shoe rabbit lives in arctic cold regions. They have thick fur and a layer of fat under their skin to keep themselves warm.

Snowy owl and Ptarmigan (a bird) lives in arctic cold regions. They have thick feathers to keep themselves warm.

Fennec fox lives in desert climates. It has huge ears enabling blood that is pumped through the larger exposed surface to lose heart quickly.
(behavioural adaptation)
Bear and Squirrel live in arctic cold regions. They hibernate, slowing down life processes such as respiration and digestion in order to survive cold and long winter periods.

Coping with light conditions
(structural adaptation)
Owl and Bat have big eyes with special eye cells that are sensitive to small amounts of light, enabling them to see well in the dark.

Rose, Rattan, Bougainvillea, Cucumber, Bittergourd and Watermelon have hooks on their stems to help them climb on a support to reach for sunlight and have tendrils to help them climb up spports for more sunlight.

Morining glory has weak and twinning stems for climbing up supports.

Money plant has clasping roots for climbing up supports.
(behavioural adaptation)
Owl and Bat have nocturnal behavior (active in the night and rest in the day) allows these animals to adapt to the light conditions of their surroundings.

Coping with availability of water sources
(structural adaptation)
Cactus has enlarged stems to store water, few stomata and waxy cells to reduce water loss. Had needle-like leaves reduce water loss through transpiration.
Has hairy leaves to reduce water loss by EVAPORATION.
(behavioural adaptation)
Camel drinks a lot of water.

Cactus had long roots that grow deep into the ground to tap water.

Coping with movement within different land habitats
(structural)
Polar bear has stiff hairs at the bottom of its feet allowing it to walk on ice without slipping.

Camel has large and padded feet enable it to walk on fine sand without sinking.

Money and Orang utan have a long tail and long limbs to swing from branch TO branch.

Aquatic habitats
Adaptation for movement in water
Shark, Barracua, Guppy and Swordtail have streamlined body shapes which reduce water resistance, allowing them to move easily.

Seagull, Frog and Duck have webbed feet for paddling in the water.

Seal, Turtle, Penguin and Dolphin have flippers to move around in water as well as to get on land.

Water boatman and Water bug have oar-like legs to propel forward in water.

(structural)
Cod and Shark store oil in their livers to stay buoyant in water.

Dolphin, Fish and Whale have a powerful tail fin to propel them forward in water.

Seal and Whale have a thick layer of blubber under their skin to stay buoyant.

Adaptations for breathing
(Structural)
Fish, Prawn, Tadpole and Dragonfly numph have gills to absorb dissolved oxygen.

Whale, Dolphin, Seal, Salion and walrus(aquatic mammal) have blowholes to breathe.

Water scorpion, Water stick insect, Mosquito pupa and Mosquito larva have breathing tubes to breathe.

(Structural)
Crab, Hermit crab and Mudskipper have gill chambers to store waterso they can breathe in dissolved oxygen from the water while on land.

Frog, Toad and Tubifex worm have special moist skins for breathing.
(Behavioural)
Water Boatman, Backswimmer, Water Spider and Great Diving beetle trap air bubbles on their bodies to breathe.
