1. Exchange materials with its environment efficently
I just had this answer but it hasn't been graded. I put 1. Meteor impacts, 2. volcanic gases and 5. Milankovitch cycles. I didn't put earthquakes because I wouldn't think it would affect the climate changing since they just affect ground movement.
A. External sex organs form
Answer:
Unicellular - Archaea and Bacteria
Multicellular - Eukarya
Explanation:
Domain is the highest taxonomic rank in the hierarchical biological classification system, above the kingdom level. There are three domains of life, the Archaea, the Bacteria, and the Eukarya.
It is crucial to study ocean microbes because THEY CONTROL THE MAJOR BIOGEOCHEMICAL CYCLES THAT KEEP EARTH'S BIOSPHERE IN BALANCE.
The ocean is made up of many microbes, which play important role in the process of biogeochemical cycling of various elements. For instance, microbes play very important role in the biogeochemical cycling of carbon and nitrogen. In the nitrogen cycle, the microbes are responsible for breaking down the protein molecules that are found in the body of dead plants and animals. The proteins are broken down into constituent amino acids, which are then released back into soils. The soil used these ammonia as sources of nitrogen for growing plants.
