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.

Two common methods to generate an aldehyde is by oxidation of an alcohol and through ozonolysis.
kotykmax [81]

Answer:

<u>a</u><u>.</u><u> </u><u>True</u><u>.</u>

Explanation:

Only primary and secondary alcohols can oxidise to give an aldehyde. But a weak oxidizing agent must be used to prevent formation of a carboxylic acid or ketone.

weak oxidizing agents: Chromyl chloride, silver/oxygen/500°C

take an example of <u>e</u><u>t</u><u>h</u><u>a</u><u>n</u><u>o</u><u>l</u><u>:</u>

<u>{ \bf{CH _{3} CH_{2}OH \:  \:  \frac{Ag/O_{2} }{500 \degree C}  >  \:  \:CH _{3} CHO}}</u>

<u>{ \sf{CH _{3} CHO \:  \: is \: ethanal}}</u>

<u>B</u><u>y</u><u> </u><u>o</u><u>z</u><u>o</u><u>n</u><u>o</u><u>l</u><u>y</u><u>s</u><u>i</u><u>s</u><u>:</u>

Here, reactants are Ozone gas, Carbon tetrachloride at a temperature (<20°C), ethanoic acid, zinc and water.

take an example of propanol:

if it undergoes ozonolysis, it gives ethanal and methanal.
