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.

Answer:
1.31x10¹¹ g/cm³
Explanation:
The mass of the proton is equal to the mass of the neutron, which is 1.67x10⁻²⁴ g, so the mass of the alpha particle is 4*1.67x10⁻²⁴ = 6.68x10⁻²⁴ g.
1 fm = 1.0x10⁻²³ cm, thus the radius of the alpha particle is 2.3x10⁻¹² cm. If the particle is a sphere, the volume of it is:
V = (4/3)*π*r³, where r is the radius, so:
V = (4/3)*π*(2.3x10⁻¹²)³
V = 5.1x10⁻³⁵ cm³
The density of the particle is the how mass exists per unit of volume, so, it's the mass divided by the volume:
d = 6.68x10⁻²⁴/5.1x10⁻³⁵
d = 1.31x10¹¹ g/cm³
Answer: Refrigerator and fire extinguisher
Explanation: Refrigerator:An evaporator fan draws air from the refrigerator and blows it over the evaporator coils. The liquid refrigerant absorbs heat from the air and the air blows back into the refrigerator at a lower temperature, cooling the refrigerator. The liquid refrigerant starts to vaporize as it heats up and moves to the compressor.
Fire extinguisher:They work by smothering the fire: when you put a layer of powder or foam on the fire, you cut the fuel off from the oxygen around it, and the fire goes out. Carbon dioxide (CO2) extinguishers contain a mixture of liquid and gaseous carbon dioxide (a nonflammable gas).
Answer:
Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products.
