Circadian timing was assessed with forced desynchrony (FD) in 10 healthy adolescents (five boys, five girls; mean age 13.7 years). Following 10 days of entrainment to a fixed light-dark (LD) schedule at home, participants were studied under dim light (<20 lux) in the laboratory. A 28-h schedule (FD) was imposed for 12×28-h cycles. Saliva was collected at 30- or 60-min intervals throughout; core temperature was measured in constant routines (CR) before and after FD. Intrinsic circadian period was estimated by linear regression using temperature minimum from CRs and dim-light salivary melatonin onsets and offsets from FD. Average intrinsic circadian period for core temperature (n=7) was 24.30±0.20, for melatonin onset was 24.33±0.21, and for melatonin offset was 24.35±0.21. Intrinsic circadian period in every adolescent was greater than 24 h.
What else can I help you with?
2 kinds of physical changes?
Intensive/Intrinsic and Extensive/Extrinsic:)2 types of physical changes are...1) If you freeze water it turns into ice- it is reversible because you can melt the ice and it turns back into water.2)REMEMBER: not all Chemical reactions are irreversible!!!!!!!!!!!!
In what general way do the intrinsic and extrinsic mechanisms of clotting differ?
extrinsic pathway of coagulation the mechanism that produces fibrin following tissue injury, beginning with formation of an activated complex between tissue factor and factor VII and leading to activation of factor X, inducing the reactions of the common pathway of coagulation.intrinsic pathway of coagulation a sequence of reactions leading to fibrin formation, beginning with the contact activation of factor XII, and resulting in the activation of factor X to initiate the common pathway of coagulation.
All the factors that could affect the outcome of an experiment are called?
Extrinsic variables.
Plasma membranes are a feature of?
Like all other cellular membranes, the plasma membrane consists of both lipids and proteins
What are the examples of intrinsive?
Intrinsic examples refer to qualities or characteristics that are inherent or essential to an object or being. For instance, the sweetness of sugar is an intrinsic property because it is a fundamental aspect of its chemical composition. Similarly, the ability of a diamond to refract light is intrinsic to its structure. In terms of motivation, intrinsic motivation can be seen when a person engages in an activity for the joy of it, such as painting purely for personal satisfaction rather than for external rewards.
What is the difference between intrinsic and extrinsic?
Extrinsic is external; intrinsic is internal.
Is miscibility a extrinsic or intrinsic?
Extrinsic
Is pressure a extrinsic or intrinsic?
Intrinsic
Which is a good conductor (Extrinsic or Intrinsic)?
Extrinsic
What is extrinsic and intrinsic evil?
Intrinsic(inherent,or inborn)evil.
What are the intrinsic and extrinsic properties of matter?
Extrinsic properties can be affected by the factors while Intrinsic is unaffected by the factors... (I'm unsure)
What is the difference between intrinsic and extrinsic sugars?
The difference between intrinsic and extrinsic sugars is that intrinsic sugars are sugars that occur naturally in the cellular structure of food while extrinsic sugars are added or are free in food. Intrinsic sugars are mostly found in fruits and vegetables. Extrinsic sugars are divided into milk sugars or lactose and non milk extrinsic sugars which are added sugar and honey. - Intrinsic motivation is your own personal motivation that comes from inside you. It is self motivation personal gain, satisfaction, or enjoyment. Extrinsic motivation is from external sources, money, coercion, fame, fortune, recognition. - Extrinsic is external; intrinsic is internal Intrinsic is inner or from inside and extrinsic is outer or from outside
Who founded intrinsic and extrinsic motivation?
Skinner
What is the example of intrinsic and extrinsic properties?
density
Difference between intrinsic and extrinsic materials?
Intrinsic materials are found within an area. Extrinsic materials do not exist within, and must be located outside of the area.
What is the opposite of extrinsic?
The opposite of extrinsic (external, unessential) would be intrinsic (innate, inherent, or essential).
Intrinsic and extrinsic motivation?
Intrinsic is the term explaining phenomenon due to internal qunatities. Extrinsic is the term explaining the same phenomenon due to foreign materials added ie external materials. In case of pure Si or Ge, intrinsic conductivity becomes possible as temperature increases. As we add trivalent or pentavalent impurities along with Si or Ge, then we get extrinsic conductivity.
