Answer:
These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division. Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed to the next generation.
 
        
             
        
        
        
A major disadvantage with molecular phylogeny is the difficulty in making assumptions in a species with variations in their phylogenies yet
they have the same genotype. The emergence
of horizontal gene transfer has also complicated molecular phylogenetics. Making
inferences on positional homology in different organisms is also difficult and complicated. 
 
        
             
        
        
        
Part A: DNA has A paired with T for RNA has U paired with T and DNA stays in the nucleus while RNA goes to get translated into amino acids (proteins). 
Part B: AUG-GCG-AAC-UGU
Part C: The newly synthesized protein as a result will have a different structure and function

Answer:
Wash hands after using the washroom.
Explanation:
Fecal oral transmission also known as oral fecal route, this transmission is defined as the route of the disease where pathogens which are present in fecal particles passes from person to the mouth.
Some common example of fecal oral transmission are fluids, fingers, flies, and food. Main cause of this transmission are poor hygiene practices, and lack of adequate sanitation.
