One of the components of the auditory system is the malleus incus and stapes that make up the auditory ossicles. Osteogenesis Imperfacta is a genetic disorder that affects the proper formation of connective tissue in the body. 
Bones, on the one hand, are constituted by connective tissue. The disorder will consequently affect the formation and integrity of the auditory ossicles, therefore, leading to hearing loss.
        
             
        
        
        
Answer 
The main reason being the amount of food available.
Explanation:
Think of it this way:
If an animal is trying to find food but another species is looking for the same prey then its going to be increasingly difficult for the species to find prey and if there's not enough of the prey species then the population of the predator to go down.
That is why its considered a limiting factor.
 
        
             
        
        
        
During cellular respiration, carbon dioxide is released to the atmosphere during the formation of acetyl coenzyme A<span>. This step involves the oxidative decarboxylation of pyruvic acid, the result of which is carbon dioxide. This carbon dioxide is uptaken by plants and used in the process of photosynthesis to produce glucose.</span>
        
                    
             
        
        
        
The type of mutation that would cause the most dramatic change in the polypeptide or protein product of a certain gene is the base-pair deletion.  A deletion is a mutation in which the part or the base is lost during the process of replication. Any number of nucleotides can be deleted from a single base to an entire piece of chromosome. 
        
             
        
        
        
The correct answer is b. no additional nucleotides would be added to a growing strand containing that nucleotide.

Nucleotides without a 3’hydroxy group are called dideoxynucleotides (ddNTD). Dideoxynucleotides are inhibitors of DNA polymerase because after being added in PCR reaction no further nucleotides can be added as no phosphodiester bond can be created (usually 3' hydroxyl group of the previous nucleotide attaches to 5' phosphate of the current nucleotide).</span>
