The process which planetesimals combine with other planetesimals is called Accretion.
There are other names which refer to as accretion. For example, Accretion geology is termed as the increase in the size of a tectonic plate by addition of materials which convergent boundary.
Accretion atmosphere is termed as the process by which water vapor which is in clouds forms water droplets around nucleation sites.
Accretion astrophysics is termed as the formation of planets and other bodies through a collection of material through gravity.
If this is for the scientific process unit, the answer is passing laws to prevent certain types of scientific research. I know because I had this question in biology.
Explanation:
they are all related to CO2 in a way
Reduce carbon dioxide emissions, pollution, and deforestation
reuse materials rather than throwing them away and needing to create more
recycle materials like metals, paper, and plastics
replace non-biodegradable materials with biodegradable
oak tree DNA is much longer than that in human and the number of chromosomes also differ
