erica [24]

Answer:

The development I found was "the creation of a 100% artificial cell"

Explanation:

In 2010 scientists led by the American Craig Venter were able to develop a 100% artificial cell. This was a great scientific advance that can improve many things in our future and guarantee a better quality of life, once it is perfected.

The experiment that allowed this development used a synthetic genome created by a computer equal to the genome of the bacteria Mycoplasma mycoides implanted in a cell of another bacteria (2) that had its entire genome removed, but that until then, had not been genetically modified. Upon receiving the genome of the bacteria Mycoplasma mycoides, bacteria 2 was reinitialized and continued its life cycle in a normal way, managing to replicate and give rise to other bacteria containing the synthetic genome.

The advantage of developing this discovery is that in the future, synthetic genomes can be used to create beneficial microorganisms that can be used in the creation of drugs, vaccines, fuels, biological molecules, among others.

If 0.60 L of a solution contains 6.6 g of NaBr, what is its molar concentration?
-BARSIC- [3]

Answer:

Molarity = moles ÷ liters

to get moles of NaBr divide grams of NaBr by its molar mass (mass of Na + mass of Bromine)

Na = 22.989769

Br = 79.904

molar mass of NaBr = 102.893769

6.6g ÷ 102.893769 = 0.064143826 moles of NaBr

0.064143826 moles ÷ 0.60 liters = 0.1069 molar concentration or 11 %
