31-41

This is an example of a niche(Big Idea 4 #13). These mussels on the rocks next to the beach are a niche because it is very abundant in its growth on the sea rocks. There were no other shelled creatures latched onto the sea rocks to grow and receive nutrients. The mussels latch onto the rock for most of their life until they are most likely pulled off the rock to be eaten. :(.

This is an example of an Amniotic egg(Big Idea 1 #4). They are capsules used to continue the growth of appendages of land animals even after the egg has been laid by the mother. The eggs evolved to provide nourishment and survive drier climates. This is an organic chicken egg. 

This is an example of ATP(Big Idea 2 #3). Also known as Adenosine Triphosphate is the energy molecule that allows for all body movements. It is not stable and therefore energy is not stored as ATP is converted when ready for use to ATP. As energy is released ATP degrades to ADP and AMP. ATP synthase is the synthesis of phosphates to form ATP.

This is an example of a catabolic pathway(Big Idea 2 #7). These chocolate labs have catabolic pathways that breakdown the food they eat into carbohydrates that can be used to make ATP. Glycolysis, the Krebs cycle, and oxidative phosphorylation are all catabolic pathways. All the molecules the dogs eat are broken down to gain access to all the nutrients possible.
This is an example of a carbohydrate(Big Idea 2 #6). This rice/pasta mix is full of carbohydrates, because it came from a plant which uses solar energy and carbon dioxide to create sugars and store them in the form of starch(glucose/carb). Animals consume this plant matter and turn it into energy by substrate and oxidative phosphorylation. 

This is an example of fermentation(Big Idea 2 #16). Fermentation is a process that occurs in humans when oxygen is not present and the Krebs cycle is not able to be completed. Specifically, humans do lactic acid fermentation. This process is reversible. The other type of fermentation, yeast based, is not reversible and therefore not as efficient.  

This shows some thing hydrophobic(Big Idea 2 #24). Olive oil is hydrophobic because it does not dissolve in water making it insoluble. The opposite is hydrophilic which is when something is attracted to water . Parts of our cell membrane are hydrophobic so that they do not dissolve in the water in which they are surrounded.

This is an example of the CAC (Big Idea 2 #27). The citric acid cycle occurs after the glucose has been broken down in to a pyruvate. Before entering the cycle it it transformed into acetyl coA. It is part of the process to turn glucose into ATP to be used to fuel our metabolic needs. oxaloacetate is the substance that the cycle uses over and over. 

This is an example of a long day plant (Big Idea2 #29). To be a long day it is measured by the time the plant spends in the cycles of light and dark. Regardless of the season, a long day plant will bloom with enough sunlight. Long day plants bloom at the critical period which occurs in the spring, explaining why most plants bloom then.
This is an example of a stomata(Big Idea 2 #33).The stomata is where H20 exits the plant and CO2 enters the plant. It is surrounded by guard cells which by their name protect the plant from damage and open and close to prevent water loss. On a leaf they are on the bottom side normally to not be in direct contact with the sunlight to reduce evaporation.

This is an example of evidence of different alleles(Big Idea 3 #7). It has a clover leaf shaped leaf as well as an oval shaped leaf.  Different alleles have caused this plant when it breed to cause the shape to differ most likely by crossing over when the cells divided to form gamers.
