Ap bio summer hunt

1. This tree has a woody stem, clearly visible as its trunk; they are used as a strong, sturdy structure to grow and also as a type of defense
2. Fish are an example of an r-strategist; these type of organisms are adapted to reproduce quickly after birth and produce large amounts of offspring because the environment is unstable

3 .This mushroom, like any other fungus, uses spores to reproduce; they are released like seeds, but differ from seeds in the amount of stored food energy inside them.
4. Hair, fingernails, toenails, etc. are all made of keratin, a type of fibrous protein that is used as a structural component for hair and nails.
5 .This is an insect; insects are a type of arthropod characterized by their exoskeleton, three pairs of jointed legs, and segmented body 6. My cat is an example of a k-strategist; these types of animals are adapted to a stable environment that does not change, so they late maturity onset, and a relatively small amount of offspring when they mate
7. This slug is an example of a hermaphrodite, a type of organism that has no separate sexes in the mating process, and have both sexual organs associated with male and female
8. This cross section of a former tree, there is a darker region in the middle named the heartwood; when the tree is alive; heartwood grows from the inside out and is more resistant to decay
9. Flowers exhibit radial symmetry, meaning they have multiple lines of symmetry extending from one fixed center
10. This is a fungus. Fungi are characterized by spores used for reproduction, and chitin used in cell walls rather than cellulose 11. Fermentation is an anaerobic process used by some organisms like yeast to convert carbohydrates into simpler compounds. One compound produced from this process is ethanol, or more commonly known, alcohol
12. This orange is an example of a fleshy fruit - characterized by a thick pulpy wall 13. One defining characteristic of an insect is its exoskeleton, a skeleton outside of an animal's body rather than inside. They support and protect the animal
14. All animals have a specific diploid chromosome number associated with their chromosomes that is always even. Since I am human, my hand has a diploid chromosome number of 46 chromosomes 15. This is an example of a deciduous leaf - meaning these leaves will be lost once a year in a process called abscission
16. This is an example of a conifer leaf - in contrast to deciduous leaves; conifers do not fall off the tree at any time in the year, and stay there the whole time. Hence their name, evergreen
17. This worm is also an example of an annelid - a large phylum meaning "ringed worm" that contains mainly segmented worms from all types of environments
18. Since this spider is an arthropod, one defining characteristic is its exoskeleton. In this case, the exoskeleton is made of chitin - a large carbohydrate 19. This spider is an example of an arthropod. Arthropods are invertebrates that have exoskeletons, a segmented body, and jointed appendages 20. This is the thorn of a plant; these structures are used on plants and other flowers as a defense mechanism against predators or other dangers
21. In all plants, there is a hormone called ethylene with formula C2H4. Ethylene acts as a stimulant to start fruit ripening, opening of flowers, or shedding of leaves

22. These are female pine cones - cones are used as reproductive structures in conifers, with the females producing the seeds in the easily recognized shape
23. Since a spider is an arthropod, one defining characteristic is its segmented body. Each section of the body is in a separate spot 24. This bug living on the stem of a plant has a tiny probe in its anus that it uses to absorb the water traveling in the stem, thus taking the plants water supply invoking parasitism
25. These snakes are examples of ectotherms. Ectotherms are a type of animal that must regulate their body temperature through external means, such as the sun
26. A mouse is an example of an endotherm. Being the opposite of an ectotherm, endotherms can self-regulate their own body temperature at a comfortable temperature 27. This plant grows in a environment with little water so it has adapted to store it, demonstrating adaptation of a plant 28. This rock has a collection of lichen on it - lichen is a type of collection of organisms working together in a symbiotic relationship. It is a composite of fungus and another photosynthetic partner 29. In your stomach, there are types of bacteria that help to digest the food you eat. They gain energy from you, and you benefit from their aid in digestion - this is an example of mutualism, where organisms live in a symbiotic relationship that benefits both parties

30. In your saliva, there are enzymes which start the digestion process as soon as food enters your mouth. Enzymes are proteins in your body that catalyze necessary chemical reactions for your health
