Which solution of ethyl alcohol is more effective at inhibiting microbial growth: a 70% solution or a 100% solution? Why?
Triss [41]

Answer:

70% solution is more effective

Explanation:

The 70% solution is more effective at inhibiting microbial growth than the 100% solution of the ethyl alcohol.

This is because the pure ethyl alcohol coagulates the protein that is in contact with it.

Also, pure alcohol will tend to evaporate faster than the 70% solution of the ethyl alcohol and it will not be that much effective.

STatiana [176]

The organisms which appeared on earth first was bacteria.

<u>Explanation:</u>

  • The first-ever living organism on Earth was a bacteria known as cyanobacteria. It is believed by scientists that it first formed around 3 billion years ago.
  • When the Earth was first formed, it was inhospitable for a long time until 3.8 billion years ago approximately, the core cooled down and the level of oxygen had risen. This, along with photosynthesis resulted in the formation of Cyanobacteria.
  • These organisms were capable of carrying out the process of photosynthesis by which they prepared their food. These were known as common ancestors. All the living organisms thereafter are known to be their descendants.
