<span>Answer is: atomic number
of resulting atom is 88.
Alpha particle is nucleus of a helium-4 atom, which is made of
two protons and two neutrons.
Nuclear reaction: ²³</span>²Th → ²²⁸Ra + α (alpha
particle).
Alpha
decay is radioactive decay in which an atomic
nucleus emits an alpha particle (helium nucleus) and transforms
into an atom with an atomic number that is reduced by
two and mass number that is reduced by four.
 
        
             
        
        
        
It's adenosine triphosphate !
it has Penrose sugar and phosphate as backbone ! 
and nitrogenous base ... adenine.... in the middle !
        
             
        
        
        
I think the answer is a but I am not for sure
        
             
        
        
        
Answer:
 I would say that it is the bond called complementary hydrogen bonds
Explanation:
The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together.
 
        
             
        
        
        
Explanation:
Given parameters: 
Initial volume V1 = 200cm³
Initial temperature = 60°C 
Final temperature = 120°C 
Unknown: 
Final volume = ? 
Solution: 
According to Charles law, at constant pressure, the volume of a given mass of gas is directly proportional to temperature. 
mathematically;
     
 1 and 2 are the initial and final states 
 V is the volume and T is the temperature
convert the temperature to kelvin
 T1 = 60 + 273 = 333K 
  T2 = 120 + 273 = 393K 
Input the parameters; 

  final volume is 236cm³
