9. Territorial Behavior

8. Introduced Species
This picture is of two Mute Swans (Cygnus olor). The mute swan is an introduced species here in Ohio, outside of its native range of Eurasia. An introduced species is a species which has been placed, or introduced, outside of its native range. Mute swans are a good example because they were introduced to this continent as ornamentals by europeans, and are an established invasive.
7. Genetically modified organism
This is a cornfield. This picture represents a genetically modified organism, Corn (Zea mays). A genetically modified organism is one whose genes have been manipulated using genetic engineering techniques. 88% of agricultural corn in the US is GM. Most corn is genetically modified to make it more resistant to pests and pesticides, and grow more vigorously.
6. Fermentation
I toured the Canton Brewing Company today, where Beer is brewed. Fermentation is the metabolic process by which sugars (carbohydrates) are broken down into acids, gases, or alcohols. This picture represents fermentation because in this facility, yeast breaks sugars in grain down into ethanol, or drinking alcohol through fermentation.
5. Gymnosperm cone
This is the cone of a Sugar Pine (Pinus lambertina). The Sugar Pine Cone is an example of a female gymnosperm cone. Coniferous gymnosperms have exposed seeds, as opposed to the fruity seeds of angiosperms. The Sugar Pine cone is an excellent example of a female cone, as it has the longest cone of all the conifers.
4. Parasitism
This is a picture of an Oak Apple-Gall. This is an example of parasitism. Parasitism is a symbiotic relationship in which a parasite benefits at the expense of the host. The gall wasp lays its eggs inside a host oak leaf, and the hatched eggs eat the leaf causing it to form a growth around the insects.
3. Gymnosperm Leaf
This is a fossilized Gymnosperm leaf. A gymnosperm is a vascular plant that reproduces without use of a fruit, using exposed seeds (Gymnosperm translates to naked seed). The leaf pictured here is a fossilized Redwood, within the Conifers, which are within gymnosperms.
Gymnosperms often have needle-like leaves.

2. Adaptation of an animal
This is a picture of a Rainbow Darter (Etheostoma caeruleum). The Rainbow darter is an example of an adaptation of an animal. An adaptation is where a trait is modified to better suit an animal or plant's living conditions. Percid fish typically have a swim bladder to help them maintain their position in the water column. The Rainbow Darter, though a percid, has done away with its swim bladder so that it can live in riffles.
1. Radial symmetry
This is a picture of a starfish. Starfish are an example of radial symmetry. Radial symmetry is a feature in which an organism has no left or right side, only top and bottom. The pieces of this organism are roughly identical in all directions. This starfish has five roughly identical lobes centered around the mouth.
