1. Big Idea 2: Adhesion of Water
Adhesion of water is water's ability to adhere to many surfaces due to the hydrogen bonds it contains. This picture depicts this trait because of waters ability to adhere to the leaf it fell on. This picture demonstrates big idea two by showing that water, due to its capabilities, can be used by many organisms to "maintain dynamic homeostasis"
2. Big Idea 2: Cohesion of Water
Cohesion of water is waters ability to adhere to itself via hydrogen bonds. This picture depicts water cohesion because it shows a very important result of water cohesion, and that is surface tension. This picture demonstrates big idea 2 by showing the many uses of water in a biological system.
3. Big Idea 2: Enzyme
An enzyme is a catalyst that is used to accelerate many chemical reaction within a biological system. This picture depicts the enzyme salivary amylase, which is used by human beings to break down carbohydrates entering the body. The picture depicts big idea two by showing that carbohydrates, after being broken down by enzymes in the human body, are necessary building blocks of life.
A taxis is an organism's movement in direct relation towards or away from an environmental stimulus. This picture depicts an bird, which, sensing the current, moves towards the current to counter its effects. The picture depicts big idea two by showing that organisms move towards or away from molecular building blocks.
5. Big Idea 2: Kinesis
A kinesis is an organism's movement in response to a stimulus, but not oriented towards or away from it. This picture shows kinesis in a ant, who, after sensing a disruption in the path, moves around randomly without any rhyme or reason. The picture depicts big idea two by showing that organisms are usually oriented towards food, and when it is broken, some organisms completely lose track of purpose.
6. Big Idea 2: Autotroph
An autotroph is an organism that, using molecules from the surrounding area, uses sunlight to synthesize the elements into useful building blocks. This picture depicts an autotroph, which uses its leaves to absorb carbon dioxide and roots to absorb water, then uses sunlight to create them. The picture depicts big idea two by showing how organisms function mainly to mold molecules into the specific building blocks that an organism needs.
7. Big Idea 2: Fermentation
Fermentation is a metabolic process in which an organism converts carbohydrates into energy without the use of oxygen. This picture depicts alcoholic fermentation, which is used by yeast cells and creates alcohol as a waste byproduct. The picture shows big idea two by showing that organisms utilize free energy and molecular building blocks to create energy for themselves.
Lactic acid is created during lactic acid fermentation, which is used by humans when no oxygen is available for the muscles from the environment. This picture depicts lactic acid fermentation, as many humans utilize it when running, when oxygen is not readily available. The picture shows big idea two by showing the organisms utilize the molecules readily available in the environment to create energy.
9. Big Idea 2: Unsaturated Fat
Unsaturated fat is a fatty acid in which there is a double bond, resulting in a kink in the fatty acid chain. This picture depicts unsaturated fat by depicting olive oil, which is an unsaturated fat, revealed by its liquid form at room temperature. This picture shows big idea two by showing that organisms may have a particular use for unsaturated fats because of its liquid form.
10. Big Idea 2: Saturated Fat
Saturated Fat is a fatty acid where there is no double bond, resulting in a straight chain. The picture shows butter, which is a solid at room temperature, as all saturated fats are because of their condensed form. The picture shows big idea two by showing that animals may have use for saturated fat because of its properties.
11. Big Idea 2: Heterotroph
Heterotrophs are organisms that can cannot create their own food from the surrounding area and are forced to eat their building blocks. This picture shows pure cane sugar, which much be used by heterotrophs, as they cannot make sugars. The picture shows big idea two by revealing that organisms must utilize free energy from the outside area to make building blocks.
12. Big Idea 2: Cellulose
Cellulose is a main constituent of the walls of plant cells and is composed of carbohydrates. This picture depicts a part of the stem of a plant, which is composed mainly of cellulose. The picture shows big idea two by revealing that plants use building blocks to help themselves in creating cell walls.
Catabolic pathways are pathways that break down specific building blocks into monomers using exergonic reactions. This picture depicts catabolic pathways in that a car breaks down gasoline to create energy to power itself. The picture shows big idea two by showing how specific molecules can be used by an organism to power other activities.
Entropy is the universe's leanings toward disorder instead of order. This picture depicts entropy by showing that the forest is naturally in disorder. The picture shows big idea two by revealing that free energy is scattered around and building blocks may be hard to find for organisms, also showing that animals themselves tend towards entropy.
Homeostasis is the ability of a cell to maintain inner equality in itself through regulation of what enters through the cell membrane. The picture shows homeostasis, as the pill represents the cell, for it regulates its internal environment. The picture shows big idea two by revealing that organisms use building blocks, such as phospholipids, to maintain homeostasis in the cell body.
A hypotonic solution is a solution where the solution is not as full as the the thing that is immersed. This picture shows a hypotonic solution, as the thing immersed contains many particles, while the outside does not. It reveals big idea two, for organisms use building blocks to maintain homeostasis in themselves.
A hypertonic solution is a solution where the solution has a higher concentration than what is immersed in it. The picture shows a hypertonic solution, as the item inside has nothing in it, while the outside solution has a much greater concentration. The picture shows big idea two by revealing that dynamic homeostasis can be achieved by use of building blocks to keep unnecessary objects from getting inside a cell.
18. Big Idea 2: Isotonic
A isotonic solution is a solution where the concentration inside and outside the solution is the same. This picture shows that there is no concentration inside or outside the solution, so both have the same concentration. The picture shows big idea two by revealing that dynamic homeostasis can be achieved by the use of simple osmosis, and can be helped by the building blocks used to make the cell membrane.
19. Big Idea 2: Hydrophilic
A hydrophilic molecule is a molecule that can bond to hydrogen atoms and is usually polar. The picture shown depicts a hydrophilic substance, as the piece of bread shown will dissolve inside the water. The picture reveals big idea two by showing that hydrophilic substances, such as several building blocks, can easily enter the cell membrane, due to to the phospholipid bilayer.
20. Big Idea 2: Hydrophobic
A hydrophobic molecule is a molecule that cannot bond to hydrogen atoms in water and is a non polar substance. The picture shown depicts a hydrophobic substance, as vegetable oil will not dissolve in water. The picture shows big picture two by revealing that hydrophobic substances cannot easily pass through the cell membrane.
