No predators exist to eat them and keep the population at a stable size.
        
             
        
        
        
Depends on what type of teeth 
if carnivore teeth than they can be similar by both being sharp and used to test through meat but could possibly be different size. 
or herbivore teeth. can be both a the shape of your front teeth and be different by shape. 
or omnivore teeth. can be different by the sharp and dull teeth. like in your mouth.
        
                    
             
        
        
        
Answer:
A frameshift mutation is a genetic mutation caused by a deletion or insertion in a DNA sequence that shifts the way the sequence is read. ... For instance, if just one nucleotide is deleted from the sequence, then all of the codons including and after the mutation will have a disrupted reading frame.
 
        
             
        
        
        
<u>Answer</u>: 
Chromosomes control cell processes by coding for the production of all a cell's proteins. 
<u>Explanation</u>:
Chromosomes are the complex structures that are made up of DNA and attached histone proteins that stabilize the nucleosome structure. DNA is made up of a sequence of polynucleotides that encodes the genetic information of that organism. 
The combination of three nucleotides known as triplet codon provides a unique code for a particular amino acid. After transcription of the DNA sequence into mRNA, it is sent to the cytoplasm of the cell to be translated into a particular protein. There are many proteins in a cell each having different sequence and hence they differ in their folding which give them a particular structure to perform a particular activity. Hence different DNA sequences encode the information for different sequences of amino acid in a polypeptide chain which makes the protein.
 
        
             
        
        
        
Answer:
Many Middle Eastern countries have been transitioning from largely rural living to urban living. City populations are growing quickly as people move to find jobs. However, environmental problems have come with this rapid urbanization. Many urban areas are experiencing air and water pollution. Air pollution is occurring due to the region's reliance on toxic energy sources, oil and gas. Oil and gas release emissions into the air when consumed by factories or cars. Cities are also experiencing water pollution issues due to a lack of waste treatment options. Without places to dispose of waste, people are dumping sewage and industrial waste into water sources. Finally, urban coastal areas are having problems with coastal degradation. Soil erodes and wildlife habitats are destroyed as land is changed for urban development.
