DNA has 3 components; phosphate, a sugar called deoxyribose (a 5 carbon sugar as opposed to the sugar in the picture which is a 6 carbon sugar - glucose) and a nitrogenous base (adenine, thymine, guanosine or cytosine). So if you look at those 3 pictures, the only one is the nucleotide that's part of the DNA.

Re-read the question: the presence of phosphorous is the answer!!

According to Thorndike's law of effect,
blagie [28]

Thorndike's law of effect is described below.

Explanation:

  • Operant Conditioning. A form of associative learning in which the consequences of a behavior change the probability of the behavior's occurance. According to Thorndike's Law of Effect. Behaviors followed by bad results are less likely to occur and behaviors followed by good results are more likely to occur again.
  • The law of effect is a psychology principle advanced by Edward Thorndike in 1898 on the matter of behavioral conditioning (not then formulated as such) which states that "responses that produce a satisfying effect in a particular situation become more likely to occur again in that situation, and responses that produce
  • Thorndike's Law of Effect states that a response followed by a pleasant consequence is more likely to be repeated, whereas a response followed by an unpleasant consequence is more likely to be diminished. ... This special stimulus has the effect of increasing the behavior occurring just before the reinforcer.
  • Law of effect. Law of Effect. The law of effect states that if a response in the presence of a stimulus is followed by a satisfying event, the association between the stimulus and the response is strengthened.

Scientific thinking: how can scientists assess the health risks of trans fats
Klio2033 [76]
Scientists can access the risks of trans fats by conducting an appropriate experiment which will show the effects of the fats on the human system.
This can be done by feeding known quantity of trans fats to rats over a specific period of time. During the period, the change in the rat weights will be measured on the daily basis and every other changes that is noted in the rats will be noted down. A control group of rats will be included in the experiment; these rats will be given normal rat feeds and not trans fats.
 When the period of feeding is completed, the rats will be killed, all the organs in the rats such as liver, blood, brains, kidney, etc will be harvested and these organs will then be biochemically analysed in order to compare the changes in them with that of a normal rats.
Rats are usually used in biochemical research because their systems and that of human is comparable. Any negative effect of trans fats that is noted in the rats will also hold true for human beings.
