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.

How do emulsifiers help oil and water to mix and not separate?
Olin [163]

Answer:

To prevent the mixture from separating substances called emulsifiers can be added. These help to form and stabilise the emulsions, preventing or slowing the water and fat/oil from separating. ... The hydrophilic end of the emulsifier molecule is attracted to the water and the hydrophobic end is attracted to the fat/oil.

Consider the following balanced equation for the following reaction:
balandron [24]

<u>Answer:</u> The amount of carbon dioxide formed in the reaction is 47.48 grams

<u>Explanation:</u>

For the given chemical equation:

15O_2(g)+2C_6H_5COOH(aq.)\rightarrow 14CO_2(g)+6H_2O(l)

To calculate the actual yield of carbon dioxide, we use the equation:

\%\text{ yield}=\frac{\text{Actual yield}}{\text{Theoretical yield}}\times 100

Percentage yield of carbon dioxide = 83 %

Theoretical yield of carbon dioxide = 1.30 moles

Putting values in above equation, we get:

83=\frac{\text{Actual yield of carbon dioxide}}{1.30moles}\times 100\\\\\text{Actual yield of carbon dioxide}=\frac{1.30\times 83}{100}=1.079moles

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Molar mass of carbon dioxide = 44 g/mol

Moles of carbon dioxide = 1.079 moles

Putting values in above equation, we get:

1.079mol=\frac{\text{Mass of carbon dioxide}}{44g/mol}\\\\\text{Mass of carbon dioxide}=(1.079mol\times 44g/mol)=47.48g

Hence, the amount of carbon dioxide formed in the reaction is 47.48 grams
