adaptation
a trait that improves the survival and or fitness of organisms that express a trait compared to alternative traits and especially to the ancestral condition in the population from which the adaptation evolved. natural selection is the only mechanism known to cause the evolution of adaptations
afferent
moving towards a particular structure often the CNS could be action potential or blood flow
amino acid
molecule or monomer of a protein, consist of one or more chains of amino acids, the sequence of the amino acid chain causes the protein to fold into a shape that is physiologically active. the amino acid sequence of proteins are encoded in the genes
bipedalism
walking upright with two feet (humans birds and apes walk bipedally) (humans birds cockroaches lizards run bipedally)
desiccation
the state or process of extreme drying due to the removal of water from the environment or organism
DNA
carries genetic instructions, consists of two strands that wind around eachother to make a double helix
effector
cells, tissue, orgains carrying out the changes necessary the CNS to maintain homeostasis (glands and muscle)
efferent
moving away from a region often the CNS
etiology
the cause or root of a disease
evolution
descent with modification , evolution explain how all life on earth shares a common ancestor
feedback
flow of info along a closed loop could be neg or pos, involves regulated variable, a sensor, the CNS/hypothalms, an effector
feedforward
open loop, predicts change and acts before it happens
genotype
collection of genes, DNA
phenotype
expression of the genotype contributes to individuals observable traits
