A laboratory technician is required to prepare a quarter normal saline solution (0.22% w/v) from the stock normal saline solution. 1. What is the dilution factor required? I have 4-fold dilution - is that correct? 2. Ise this dilution factor to calculate...

Which is the correct base pairing: Adenine - Guanine Adenine - Cytosine Thymine - Guanine Thymine - Adenine Cytosine - Thymine

Thanks to SraJMcGin for the links but I really don't understand this and am hoping someone can give me a really simple explanation so I get get my head around the question..... Describe the cellular specialisation that has occured in muscle cells.

OK third time lucky - hoping someone out there knows the answer to this one.... Describe the cellular specialisation that has occured in muscle cells.

If a radioactive isotope has half life of 5 days,how long will it take for its radioactive strength to be a maximum of one thousandth,(1/1000) of its original value? Can anyone give me a VERY SIMPLE explanation of this please? Thank you.
