The correct option is this: THE DISCOVERY OF CODONS.
<span>Codons refers to a sequence of three DNA or RNA nucleotides which corresponds to a particular amino acid or a stop signal during protein synthesis. Thus, the genetic codon is used to translate the information that are encoded within genetic materials into proteins. The genetic codons was discovered by Marshall Nirenberg and Heinrich Matthaeis, who deciphered the entire genetic codes by matching amino acids to synthetic triplet nucleotides.</span>

What do you think about scientists around the world prefer to use SI units instead of other kind of units?
vlada-n [284]

Answer: I think scientist prefers to use SI because it’s much easier and you can covert between units.

Explanation:

Its is easier for scientists to communicate with one another if they all use the same units. In addition, it is very easy to convert between different SI units

lana66690 [7]

The given question is incomplete, the complete question is:

One of Loraine's friends, Marie, started purchasing raw, unpasteurized milk for her children. Marie insists that pasteurization reduces the nutritional quality of milk and raw milk contains phytochemicals that are destroyed during pasteurization. What should Loraine tell her friend about pasteurization?

A: The pasteurization process heats foods to kill pathogenic microorganisms and reduce the total number of bacteria.

B: The pasteurization process denatures protein and kills harmful prions.

C: The pasteurization process evenly distributes fat particles throughout the milk so the cream doesn't rise to the top of the milk.

D: The pasteurization process releases bound calcium and increases absorbable dietary calcium in cow's milk.

Answer:

The correct answer is option A, that is, by the process of pasteurization food is heated in order to eliminate the pathogenic microbes, which eventually diminishes the bacterial number.

Explanation:

The process by which some of the components of food like dairy products and juice are heated slightly so that the harmful bacteria and pathogens get eliminated from the food is known as pasteurization. It is important to kill such bacteria and pathogens as it may cause certain diseases after consumption.  

Pasteurization is the process of treating non-packaged and packaged foods with a mild heat, which is generally less than 100 degree C. The process helps in extending the shelf-life of the food product by eliminating the harmful bacteria and pathogens from it.

You have been studying a large lake ecosystem. You learn that toxins have been dumped into the water. You predict that the popul
Shtirlitz [24]

The correct answer is predatory birds.  

The flowing of toxic chemicals and heavy metals into the water body when the agricultural, industrial, and human wastes run off or are discharged intentionally into the water body is known as biomagnification. These pollutants result in genetic mutations, disease, reproductive difficulties, birth defects, death, and behavioral modifications in various marine species.  

However, the extremity of the destruction varies significantly among the species. In various circumstances, the animals close to the top of the food chain are most influenced by the procedure of biomagnification.  

Several of the harmful toxins get settle at the lower level in a water body and are then consumed by the species, which feed or live on the bottom dwellers. As these constituents are not digested, they gathered inside the bodies of the species, which consumes them.  

It signifies that the higher level predators, like fish, birds, or marine mammals accumulate more harmful concentrations of toxic substances in comparison to the animals lower on the food chain. Thus, in the given case, the more concentrated amount of toxins would be found in the predatory birds.
