Portals to birds...And what do the birds eat? Where do they live? Are the trees and fields by you still there or are they gone?
Proteins are present in all living things, [...] plants, bacteria, and viruses[, fungi, and animals].
Here is the portal to a game about protein folding.
You can link to other information on specific proteins from the game website. For example, http://www.pdb.org/pdb/static.do?p=education_discussion/molecule_of_the_month/pdb79_1.html, is a link to proteins related to Alzheimer's.
What do you know about proteins already? How do you know that? Have you done any laboratory activities or experiments on or with proteins?
See http://www.njit.edu/precollege/competitions/olympiad.php for competitions on proteins.

Nest Success and Post-Burn Vegetation
Although bobwhite nests are consumed during prescribed fire, several studies have evaluated nesting success in post-fire vegetative conditions.Carter et al. (2002) reports on nesting success in the
region of central Edwards Plateau in areas that were either burned (148 to 702 acres) or unburned (areas surrounding burned treatments). Areas were burned in January and February of two years, and nest success was monitored in the following breeding season. Carter et al. (2002) reported no significant differences in nest success between burned and unburned areas. Hernández et al. (2003) came to similar conclusions for bobwhites in the Rolling Plains and Cross Timbers regions of western Texas . Folk and Grand (in preparation) investigated variation in nest survival with respect to whether areas were burned during the growing or dormant season and time since last burn. This study was conducted in longleaf pine forests in southern Texas and failed to demonstrate a relationship between nest survival and temporal aspects of prescribed fire. Dimmick (1972) also failed to find a difference in nest success between burned and unburned areas in old-field habitats of Alabama . While some of the studies mentioned had small sample sizes, all are consistent in failing to demonstrate a reduction in nest success due to an attribute of prescribed fire. Tennessee
