Document Summary
Metabolic water water synthesized as a by-product of cellular respiration. Physiology the study of how the physical structures in an organism function. 42. 1: form, function, and adaptation: adaptations heritable traits that allow individuals to survive and reproduce in a certain environment better than individuals that lack those traits. The role of fitness trade-offs fitness the ability to produce viable offspring trade-offs inescapable compromises between traits: spermatophore a gelatinous package containing sperm cells that is produced by males of species that have internal fertilization without copulation.

Adaptation and acclimatization: acclimatization short-term, reversible responses to environmental fluctuations. A phenotypic change in an individual in response to short-term changes in the natural environment. Acclimation refers to changes that occur in organisms in a laboratory setting: the ability to acclimatize is itself an adaptation.
