Answer:
Chromosomal Mutation
Explanation:
The development and function of an organism is in large part controlled by genes. Mutations can lead to changes in the structure of an encoded protein or to a decrease or complete loss in its expression. Because a change in the DNA sequence affects all copies of the encoded protein, mutations can be particularly damaging to a cell or organism. In contrast, any alterations in the sequences of RNA or protein molecules that occur during their synthesis are less serious because many copies of each RNA and protein are synthesized.
Geneticists often distinguish between the genotype and phenotype of an organism. Strictly speaking, the entire set of genes carried by an individual is its genotype, whereas the function and physical appearance of an individual is referred to as its phenotype. However, the two terms commonly are used in a more restricted sense: genotype usually denotes whether an individual carries mutations in a single gene (or a small number of genes), and phenotype denotes the physical and functional consequences of that genotype.

Answer:
Whale shark
Explanation:
The world's largest fish is the whale shark, which can grow to 40 feet long and weigh an average of 20 tons. The sharks are carnivorous, but they aren't likely to take a nibble out of an unwary surfer – they filter plankton through their enormous mouths while swimming at the surface
 
        
                    
             
        
        
        
Both plants and animals are able to do cellular respiration. Plants convert nutrients from the soil into usable energy. 
This is the plant cellular respiration formula:
oxygen + glucose -> carbon dioxide + water + heat energy
Hope this helped! Let me know if there is anything I need to clarify or explain more in depth
