Scavenger Hunt #4

Adaptation of an animal--

This is a grizzly bear that lives in Denali national park in Alaska. I saw two the first day that I was there. They  both had somewhat of a blonde coat, more so than one would expect a grizzly bear to have. Later, I found out that this is due to their diet. The grizzlies in Denali do not live near a river; therefore, they have to adapt to their environment and eat only berries and vegetation. The grizzlies in south Alaska have access to the Kenai river, and other rivers, where they eat mostly salmon. This is said to cause the southern grizzlies to have a darker coat.

Mating Behavior--

These are salmon eggs. I went fishing in Kenai, Alaska during the middle of July. This is the time that salmon from the ocean swim up stream of the rivers to lay their eggs. There are so many that each person can catch up to three each day and there will still be enough to have a steady population each year. This is the mating behavior of salmon.. happens every year. I watched the guy fillet the fish and he pointed out the eggs to me.. I was very fascinated. He just thought I was weird to take pictures of the insides of the fish..

Enzyme

The brown organ is the liver--a liver of a salmon fish.The liver secretes a digestive enzyme called bile that is stored in the gall bladder. An enzyme is something produced by a living organism that acts as a catalyst.

Altruistic Behavior

This is Shanook. She is a mom of five alaskan husky puppies in Girdwood, Alaska. They live on a glacier where dog sledding takes place. She shows altruistic behavior when she cares for her pups more before doing anything else. She protects them very well, and always makes sure they are safe before making herself comfortable.

Cuticle Layer of a Plant

This is a flower from Nicaragua. Nicaragua is very hot, with a very strong sun. Water is something that is somewhat scarce in Nicaragua, at least clean water that is. Plants are the least of concern for the people there. Therefore, they do not get watered by hand; they only receive water from the times that it rains. Therefore, this plant develops a cuticle layer that is a waxy coating that helps the plant from loosing water to evaporation.
