Carbon dioxide goes through plants, which they turn into oxygen. Humans and animals take in the oxygen and breathe out carbon dioxide. Then it repeats.

The addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes because they help to condense it into chromatin.
<h3>What is the relationship between histones and DNA?</h3>
Histones are a family of basic proteins that associate with DNA in the nucleus and help to condense it into chromatin. Nuclear DNA does not appear on free linear strands; it is highly condensed and involves histones to fit inside the nucleus and participate in the formation of chromosomes.
<h3>How does DNA compact with histones?</h3>
Each chromosome is made up of a single molecule of double-stranded DNA wrapped around histones, the nucleosome. This fiber rewinds into a second level of compression, known as the solenoid. Most of the time, cells keep the DNA compacted in the selenoid loops attached to the chromosomal backbone.
Whit this information, we can conclude that the addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes because they help to condense it into chromatin.

Answer:
The condition of the Earth had to become favourable before it could support any form of life.
The formation of the different layers around the earth like the ozone layer was necessary before life could originate. Primitive species such as some prokaryotes were able to live in hydrothermal conditions during the initial times. With the passage of time, as the concentration of oxygen increased due to photosynthetic prokaryotes, situations became favourable for eukaryotic organisms to arise.
