type 2 diabetes mellitus

Front

Diabetes in which the body produces insulin, but not enough, or there is insulin resistance. The patient usually is not dependent on insulin for survival.

Back

taxis

Front

Automatic, oriented movement toward or away from some stimuli.

Back

phytochrome

Front

A class of light receptors in plants. Mostly absorbing red light, these photoreceptors regulate many plant responses, including seed germination and shade avoidance.

Back

critical night length

Front

The number of hours of darkness that determines whether or not a plant will flower.

Back

hibernation

Front

long-term torpor that is an adaptation to winter cold and food scarcity

Back

thermoregulation

Front

Process of maintaining an internal temperature within a tolerable range.

Back

vasoconstriction

Front

Reduces blood flow and heat transfer by decreasing the diameter of superficial blood vessels.

Back

photoperiodism

Front

A physiological response to photoperiod, the relative lengths of night and day. An example of photoperiodism is flowering.

Back

negative feedback

Front

A type of regulation that responds to a change in conditions by initiating responses that will counteract the change. Maintains a steady state.

Back

estivation

Front

Summer torpor. Enables animals to survive long periods of high temperatures and scarce water supplies.

Back

type 1 diabetes mellitus

Front

Diabetes in which no beta-cell production of insulin occurs and the patient is dependent on insulin for survival.

Back

day-neutral plants

Front

A plant whose flowering is not affected by photoperiod.

Back

homeostasis

Front

"Steady state" or "constant internal milieu".

Back

chemotaxis

Front

The phenomenon whereby somatic cells, bacteria, and other organisms direct their movements according to certain chemicals in their environment.

Back

migration

Front

Relatively long-distance movement of individuals, usually on a seasonal basis.

Back

short-day plants

Front

A plant that flowers only when the light period is shorter than a critical length. Usually fall or winter.

Back

daily torpor

Front

In small mammals and birds, daily lowering of metabolism that allows them to survive on stored energy.

Back

phototropism

Front

Growth of a plant shoot toward or away from light.

Back

kinesis

Front

A simple change in activity or turning rate in response to a stimuli.

Back

vasodialation

Front

Increases in the diameter of superficial blood vessels; cools the body.

Back

positive feedback

Front

A type of regulation that responds to a change in conditions by initiating responses that will amplify the change. Takes organism away from a steady state.

Back

long-day plants

Front

A plant that flowers only when the light period is longer than a critical length. Usually spring or early summer.

Back

ethylene

Front

Plant hormone that promotes leaf abscission and fruit ripening.

Back

auxin

Front

Indoleacetic acid (IAA), a natural plant hormone that has a variety of effects, including cell elongation, root formation, secondary growth, and fruit growth.

Back

circadian rhythms

Front

A physiological cycle of about 24 hours that is present in all eukaryotic organisms and that persists even in the absence of external cues.

Back

torpor

Front

Physiological state in which activity is low and metabolism decreases.
