<u>Bacterial growthon the  agar in a Petric dish:</u>
Nutrient agar gives these assets to numerous sorts of organisms, from parasites like yeast and form to basic microorganisms, for example, Streptococcus and Staphylococcus. 
The microorganisms that can be developed on complex media, for example, supplement agar can be depicted as nonfastidious life forms. Microscopic organisms are found in each natural surroundings on Earth: soil, rock, seas and even cold day off. Some live in or on different life forms including plants and creatures including people. 
There is around 10 fold the number of bacterial cells as human cells in the human body. In the two people and microorganisms, a codon made of three thymine DNA-letters will code for an amino corrosive called Phenylalanine. This code is regular to the two people and microscopic organisms, and surely, for most living things.

Answer:
Toucans disperse seeds of key forest species such as juçara palms by eating the fruit and defecating the seeds in new locations, sometimes more than a kilometer away. If there are no toucans, is the genetic diversity of palms likely to increase or decrease within forest fragments (and why)?
The genetic diversity of palm will totally decrease as a result of absence of Toucans dispersal of palms seeds which would not allow the seeds to be randomly grown anywhere. Dispersal has great impact on biodiversity of fruits because it enables the distribution of seeds to be grown everywhere

 Correct answer: A). The current hypothesis of the evolutionary relationships between organisms
The tree of life is a metaphor that expresses the idea that how life is related to ancestors. Charles Darwin first uses this in the modern biology. It is an evolutionary tree that depicts the relationship between various biological entity. It holds the data that are collected from RNA, DNA and protein analysis. It shows the current hypothesis about the evolutionary relationship among the taxa.
Hence, the correct answer would be option A.
 
        
                    
             
        
        
        
DNA stands for Deoxyribonucleic acid which means it is a nucleic acid. RNA stands for Ribonucleicacid. RNA produces proteins
DNA replicates and stores genetic information. 
RNA converts the genetic information contained within DNA to a format used to build proteins.
I would have to say the answer is A based off the information above. 
Please correct me if I'm wrong.
