Adaptations

3 Adaptions:

1. Resource Conservation: 
For animals that live in areas where resources such as food and water are hard to find. The ability to conserve fat and water in the body can mean the difference between life and death.  A stunning example of resource conservation comes from the Bactrian camel, a two-humped ungulate that lives in the rocky and arid regions of Central and Eastern Asia, where temperatures range from -20°F in winter to 100°F in summer. Bactrian camels have a couple of key adaptations that help them to survive these harsh conditions. First, their humps are filled with fat, which can be converted into energy and water in lean times. Second, they can forgo sweating until their body temperatures reach nearly 105°F
2. Hair: 
For most mammals in the wild, hair offers important protection from the elements. The musk ox is a superb example. It has an important adaptation to its bitterly cold home on the vast Alaskan tundra: Its thick, shaggy hair hangs down to the ground and gives the ox the protection it needs to endure frigid temperatures. Such fur helps the animal survive as winter temperatures drop to an average of -30°F. Some of the hair is shed in time for summer, allowing the musk ox to cool down as temperatures reach 40-50°F.
3. Size:
A lot of species in the animal kingdom try to appear larger in order to ward off predation, but the blowfish, also called a puffer or balloonfish, It has the ability to puff up to about twice its normal size in response to a predator's advance. When threatened, blowfish pump air or water into their extremely elastic stomachs to the point of being nearly spherical in shape with their spines and scales protruding. At that point they can barely move, but it doesn't usually matter since they are virtually inedible in that form.

Lab Observation 4

1.  What do you think kills the fish/shrimp--oxygen or temperature of water,  why?: I think mainly because of low oxygen in water.

2.  Did you find anything interesting in the lab?: Dead fish and Stinky sinks.

3.  what other things could kill the fish?: Starvation.

Dead Fish Piucture

Fish 2


1. Why do you think your fish lived or died: I think the fish died because there was no food.

2.  Groups with fish that are alive, how are their bottles different from yours: My group died.

3.  If you had to do it again, what would you change to keep your fish alive: Give it food.

Fish Lab (Arm)


 
   Fish Lab (Arm)


 1.  describe what happened in the experiment and propose an explanation for your observations: 
        1. Put water into the bottle.
        2. Put blue liquid into the water.
        3. Put seaweat into the bottle.
        4. Put fish into the bottle.
        5. Think up a name for the fish.

2.  explain why some of the jars changed color: 
        The blue will turn into yellow because of carbon dioxide.

3.  describe how plants and animals are dependent on each other:
         Plants provide shelter for animals and they make oxygen for the animals to live. When animals die they decompose and become natural fertilizer for plantsPlants depend on animals for nutrients, pollination and seed dispersal. 

4.  make a prediction about what will happen in one week:
         Nothing.
