Interphase-intermediate phase, DNA replicates
Prophase -coils into chromosomes, chromosomes are made of two chromatids, which join at the centromere at this stage.
Metaphase -Chromosomes line up in the middle of cell on spindles
Anaphase - Chromosomes are pulled apart to opposite ends of the cell by the spindles
Telophase - The cell splits into two cells, and the chromosomes uncoil and begin from the interphase stage again
        
                    
             
        
        
        
Normal proteins allow the substances Na + and Cl- to move correctly through the cells of the skin, the pancreas and the lungs.
In contrast, the mutated proteins prevent them from moving through the cell, this causes mucus to accumulate in the skin, in the lungs and the pancreas, a medical condition called cystic fibrosis.
        
             
        
        
        
Answer:
1. In the dispersive model, each strand of both daughter molecules contains a mixture of old and newly synthesized DNA, and in the semiconservative model, each new double helix consists of one old and one new strand.
Explanation: it helps to remember that dispersive means to disperse your DNA molecules! And semi conservative means you keep one of your old strands! Hope this helps!
 
        
             
        
        
        
Answer: Option A 
Explanation: 
The effector response that increases the body is not associated with vasodilation of dermal blood vessels.
The skins's immense blood supply helps in temperature regulation of the body. The dilated blood vessels helps in heat loss and lowers the body temperature.
Unlike, them the vasoconstriction retains heat and increases the body temperature.
So, the correct answer is option A
