A
B is wrong because mitochondria would likely absorb the stain even if it was dead.(And most cells that have been treated are dead anyway). C and D are just throwaway answers, you usually want to avoid the word "always" when drawing conclusions.
        
                    
             
        
        
        
The options provided for the question above are as follows:
A. Respiratory tract illnesses
B. Skin infection
C. Acute infectious diaherea
D. Intestinal infections.
The correction option is A.
Respiratory tract illnesses account for the majority of sickness that occur in child care settings. Such infection include those that affect the lower and the upper respiratory tracts; examples include: otitis media, sinusitis, bronchiolitis, pneumonia, etc. Children who attend out of home child care has greater risk of contacting these diseases. 
        
                    
             
        
        
        
Following two cycles are the most closely related in their role in sustaining life  are <span>carbon and oxygen 
 all</span><span> living thing need carbon because  to perform properly. because carbon is found everywhere from the ocean to the sky to rocks. The movement of carbon is known as the carbon cycle
</span><span>Oxygen is very important to living organisms. The oxygen cycle  have following steps. The oxygen cycle is  interconnected with the carbon cycle because carbon and oxygen are  combined in a molecule. The oxygen cycle  consists of animals who inhale oxygen from the atmosphere and plants that release oxygen in the atmosphere.</span>
        
                    
             
        
        
        
Answer:
Lining up of chromosomes in the cell
. 
Explanation:
Prophase begins with the Thickening of chromosome. Chromosomes are clearly visible inside the nucleus. each chromosome splits longitudinally to form two chromatids. 
The centriole in the centrosome of animal cell divides into two. The centrosphere set the centrioles free. Centrioles develop very fine eye-lash like thread called aster rays. the two asters start moving towards the opposite poles. By the end of prophase they reach at the opposite poles. 
 
        
             
        
        
        
Proteins (Polypeptides with a unique amino acid sequence) are required to guarantee that the accuracy of replication is compatible with the low frequency of errors that is needed for cell reproduction Helicases unwind the two strands of parental DNA and creates the replication fork; single strands binding proteins keep the single strands from reuniting
