Most nitrogen in commercial fertilizer comes from ? - CORRECT ANSWER -Urea
Enantiostasis - CORRECT ANSWER -
allow the internal environment to change with their surrounding environment (invertebrates
)
Ecological Physiology - CORRECT ANSWER -
the study of the interaction between an organism's biochemistry and/or general physiology
and its environment
Homeostasis and enantiostasis categories of function - CORRECT ANSWER -
1. structural integrity (shape/structure)
2. Provision of adequate energy supplies (ATP)
3. Maintenance of reactions for regulation of metabolism
,Basic mechanisms of biochemical adaptions - CORRECT ANSWER -
1. change of concentrations of macromolecules (ex: amount of enzymes being made)
2. change in microenvironments (ph and lipid of cell membrane)
3. changes in outputs/macromolecular systems (synthesis and degradation pathways)
Genetic adaptions - CORRECT ANSWER -occurs over many generations (ex: mutations)
Adaptations - CORRECT ANSWER -
Occur over 1 generation usually in one lifetime (ex: phenotypic changes like membrane lipid
composition)
Acclimation - CORRECT ANSWER -type of adaptation to one environmental factor
Acclimatization - CORRECT ANSWER -
type of adaptation of an animal to many environmental parameters like temperature, light,
humidity
Immediate adaptions - CORRECT ANSWER -
rapid; adjustments in enzyme activity like enzyme modulation
Homeostasis - CORRECT ANSWER -consistency of internal environment
Conformity - CORRECT ANSWER -
internal state of cell or organism may conform to an environment
Regulation - CORRECT ANSWER -an organism controlling its internal state
, Spacial Heterothermy - CORRECT ANSWER -Ex: body core kept than surface of tissues
Temporal Heterothermy - CORRECT ANSWER -
animals that have a constant body temperature during activity, but let their body drop with
dormancy or hibernation
Steno and Eury - CORRECT ANSWER -
these terms refer to narrow and wide ranges of tolerances
Capacity adaptions - CORRECT ANSWER -
functional properties that permit relative constancy of biological activity over varying enviro
nments
Resistance adaptions - CORRECT ANSWER -
functional properties that permit the animal to adapt to environmental extremes. (more co
mplex of an animal, less range of tolerance)
Vitamin A - CORRECT ANSWER -
for growth and development, maintenance of immune system, and good vision
Vitamin B - CORRECT ANSWER -cofactor for enzymes NAD, FAD
Vitamin C - CORRECT ANSWER -prevent scurvy; tissue repair and formation
Limies - CORRECT ANSWER -British sailors who ate limes to prevent scurvy
Vitamin D - CORRECT ANSWER -
relationship to evolution of skin pigmentation; calcium metabolism
