If the earth traps more heat, it may cause Global warming.
Note each of them:
Archaea is a single-celled microorganism with no nucleus
Bacteria is a unicellular microorganism with cell walls but lack organelles
Sarcodina is a phylum with temporary extensions of the cell. They can be parasitic.
Protista is an eukaryotic organisms that is not an animal, plant, or fungus.
The organism found is unicellular (rules out Archaea), with cell walls (characteristics of bacteria), and the ability to produce spores.
I believe that Bacteria (B) is your best answer
hope this helps
The movement of nutrients into the vascular stele requires energy, unlike the movement of water that does not require energy. This energy is provided by the phloem. Sugars are produced in the leafs, as part of the photosynthesis process, so whenever a new root is growing, or a fruit needs to grow, the phloem gets in action. With the help of the water the sugars get in the phloem, which can most simply be seen as an elevator inside the plant, that is moving nutrients up and down, on the places in which they are most needed.
