The answer is the epididymis. It is a contracted, tightly-coiled tube linking back of the testicles to the deferent duct (vas deferens). The epididymis contains three parts and these are the head, body, and tail. The head of the epididymis is positioned on larger pole of testis. It stocks sperm for maturation.
        
             
        
        
        
A MYSTERIOUS ailment has been devastating the much studied lions of the Serengeti National Park in Tanzania, and scientists said yesterday that it had been identified as canine distemper, a viral disease that causes severe neurological symptoms and death.

Answer & Explanation:
( Rh Factor ) represents the presence of the Rhesus protein in the blood. 
( Rh+ ) blood contains the rhesus protein.
( Rh- ) blood does not contain the rhesus protein. 
( Type O ) blood is the universal donor. 
( Type AB ) blood is the universal recipient. 
( Rh+ ) blood can receive Rh+ or Rh- blood. 
( Rh- ) blood can receive Rh- blood.

Answer:
The changes in the sequence of nucleotides present within a promoter is a prime cause of the defected transcriptional regulation, which may eventually result in disease. However, not every modification within the sequence of a promoter influences the regulation of transcription, it relies upon the nature and the location of the genetic defect.  
When a mutation results within the sequence of a promoter region it may hamper the usual procedures of gene stimulation by affecting the step by step alignment of the transcription factors at the promoter region. Therefore, as a consequence, a mutation within the sequence of a promoter may result in the enhancement or reduction in the level of mRNA and thus protein.
