Between 2000 and 2013, fatalities from measles decreased by approximately 75%.
<h3>What do you mean by Measles?</h3>
Measles may be defined as an acute and highly contagious viral disease that is commonly caused by a single-stranded RNA virus known as measles virus.
Fatalities caused by measles in 2000 = 582,800
Fatalities caused by measles in 2013 = 145,700
Total differnce = 437100.
Now, the percentage = 437100/582800 ×100 = 75%.
Therefore, between 2000 and 2013, fatalities from measles decreased by approximately 75%.

Correct answer is option D.
Transcription activators accelerate transcription, while transcription factors assist RNA polymerase binding.
<h2><u>
</u></h2><h2><u>
Explanation</u></h2>
Transcription factors are the proteins which help in proper binding of RNA polymerases in the promoter region of DNA so as to facilitate transcription.
Activators on the other hand, help in the enhancement of the transcription rate.
Transcriptional activators are basically proteins which bind to the regulatory elements known as enhancers so as to increase the rate of transcription. Enhancers are specific DNA sequences, which may be present in the upstream or downstream region of the gene which is going to be transcribed.
It may be noted here that transcription factors are only present in eukaryotes. In prokaryotes, sigma factors are present instead of transcription factors to facilitate proper binding of RNA polymerases on the DNA.
A drug that interacts directly with receptor sites to cause the same activity that a natural chemical would cause at that site is the instructors best response.
Explanation:
Receptors are Macromolecules which involved in chemical signalling within cells. It is possible that receptors are located in the cell surface membrane. Cellular biochemical process is regulated by Activated receptor. The drugs are capable to affect to receptor who is related to the drug’s affinity and also intrinsic efficacy.
The affinity and activity of drug is related to its chemical structure. its effect is decided by the time duration where complex persistence of drug-receptor.
Answer:
The correct answer is letter C.
