This is a picture of Purple Loosestrife. It was introduced to the east coast in the 1800s from Europe and asia. It's seeds spread through water ways which explains why it is a large problem in the northern states with lots of fresh water lakes and rivers like Minnesota and Michigan. Purple Loosestrife forms dense clumps that take over animals feeding areas.

24. Fermentation
This is a picture of bread. Bread rises through a process called fermentation. Fermentation happens when yeast and bacteria inside of the dough change carbohydrates to CO2, causing gas bubbles to form which in turn , rises the bread.

22. Seed Dispersal
These are blueberries. One way that seeds are moved is through animals. Animals would eat these blueberries and then digest everything except the seeds which could then be excreted in a new location.
21. Modified Leaf of a Plant
This is a picture of celery. The stalks in the picture are petioles. Petioles have been modified through selective breeding to be very wide so that they can hold more water.
20. Endotherm
This is my friend Owen. He is a warm blooded mammal which means that he uses his own metabolic processes to create his body temperature, therefore, he is endothermic. One process that controls our body temperature is glycolysis, which is the oxidation of glucose.
19. Cam Plant
This is a picture of a pineapple. It is classified as a Cam Plant because it's stomata stay closed during the day and only open at night to allow CO2 to enter. The CO2 is turned into a four-carbon acid and released during the day for use in the Calvin cycle. This cycle helps to retain water loss during the hottest parts of the day.
