Answer:
Tectonic plates.
Explanation:
The continents are embedded in the plates, like logs in the ice of a frozen river. As the plates move, the continents move with them. When two continental plates meet, one is dragged down beneath the other.
<span>It is believed that in the evolutionary history of life on Earth, there was the RNA world before DNA and proteins.</span> <span>RNA is a self-replicating molecule that can store and replicate genetic information and catalyze (ribozymes-RNA enzymes) reactions that are important for life. Because of these characteristics, it is possible that RNA world really existed. Because of the better stability and durability than RNA DNA later it became the predominant storage molecule.</span>
Answer:
Saprotroph, also called saprophyte or saprobe, organism that feeds on nonliving organic matter known as detritus at a microscopic level. The etymology of the word saprotroph comes from the Greek saprós (“rotten, putrid”) and trophē (“nourishment”).
Explanation:
Physics tell us how something was made because of the atoms that we have come from.
They vary on shape reproduction patterns in species. Traits that affect a organism's schedule of reproduction, selective pressures vary so life histories are very diverse. Life history traits are products of natural selection and an organisms life history comprises the traits that affect schedule of reproduction and survival, and also the traits are evolutionary outcomes reflected in the envelopment, physiology and behavior.
