Answer AND Explanation:
In spite being called the resting phase, many cellular processes take place during this phase. One of the most important of these is chromosomal replication in which each chromosome produces an exact copy of itself. The chromosomes are not visible as discrete structures but instead they appear as diffuse tangle of threads called chromatin.
Another important event is the formation of new organelles like mitochondria. There is also a build up of energy stores which is necessary to drive the mitotic process.
The answer is 'Cambrian' explosion. This took place approximately 541 million years ago. 'Explosion' refers to the evolution of a large range of new major animal phyla. Scientists know this by the large number of diverse fossils from this period. Prior to this period, organisms were single-celled, but over the Cambrian Explosion, lasting about 80 million years, life forms diversified rapidly to resemble the life forms existing today.

Answer:
I don't know the answer to the first one, but I can answer the second question. <em>Cellular respiration </em><u><em>has carbon dioxide and water as waste products</em></u><em>.</em>
Explanation:
<em>Cellular respiration</em> does <u>not</u> form glucose & oxygen and doesn't occur in the chloroplast, but does form <em>ATP energy</em>, <em>carbon dioxide</em>, & <em>water</em> and the process occurs in <em>mitochondria</em>. Photosynthesis on the other hand forms glucose & oxygen and does occur in the chloroplast.
