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.
The answer to this question should be: Calvin cycle
Calvin cycle is a chemical reaction that was done in the chloroplast of a plant. This is one of the reactions in photosynthesis. In Calvin cycle, carbon dioxide and water will be used to make carbohydrates(glucose). This reaction is forming energy using the sunlight so only autotrophic organism capable that will be able to do it.
The answer is A. - Prokatyotic cells lack a defined nucleus while eukaryotic cells do have one :) I loved learning about the cells in biology! But I noticed your question is worded a little differently so the nucleus would be the one thing a eukaryotic cell has that a prokatyotic cell does not...
