Answer:
associated with unstable air and stronger weather disturbance, there is more moisture in the air of a maritime air mass, increasing the possibility of rain, snow, and storms. forms over Canada, move down from North Pole, bring bitterly cold and dry air to the northern United States during the winter.
 
        
                    
             
        
        
        
The sister chromatids are then pulled apart by the mitotic spindle which pulls one chromatid to one pole and the other chromatid to the opposite pole.
The chromosomes line up neatly end-to-end along the centre (equator) of the cell.
The centrioles are now at opposite poles of the cell with the mitotic spindle fibres extending from them.
The mitotic spindle fibres attach to each of the sister chromatids.
The DNA in the cell is copied in preparation for cell division, this results in two identical full sets of chromosomes?.
Outside of the nucleus? are two centrosomes, each containing a pair of centrioles, these structures are critical for the process of cell division.
        
                    
             
        
        
        
A=2 
B=red blood cells rely on catalase, catalase decomposes hydrogen peroxide 
C=The effect of replacing his is that the hydrophobic amino acid would not do well with water 
D= the hydrophobic amino acid is like oil and water and wouldn’t do well decomposing hydrogen peroxide
        
             
        
        
        
Answer and Explanation:
When a cell is freezed, it cytoplasm-which is mostly water- is frozen and its volume expands. In consequence, pressure inside the cell increases and that causes damage to the outer wall. 
The same occur in an unopened softdrink when it freezes. The volume inside the container increases and the pressure increases. If this volume increment is not considered before freezing the liquid, it could cause the container damage or breaking.
