Answer:
Zooxanthellae only
Explanation:
Zooxanthellae is a colloquial term for single-celled dinoflagellates that are able to live in symbiosis with diverse marine invertebrates including demosponges, corals, jellyfish, and nudibranchs.
In evolutionary biology, phylogenetic trees are used to exhibit and illustrate the evolutionary relationships of two or more organisms, and identify the origins of life altogether. To achieve this, there are three methods of classification which are phonetics, cladistics, and taxonomic groups.
The main difference between a prokaryotic cell and a eukaryotic cell is that the prokaryotic cell have no true nucleus instead its genetic material is just suspended in its cytoplasm termed as nucleoid. The nucleus when viewed under the microscope is a membrane bound which is easily distingushable compared to the nucleoid.
Another distinguishing feature is that prokaryotic cells are usually smaller than eukaryotic cells.
Answer:
3 characteristic
Explanation:
1- it contains sulfur when bacteria found sulfur in the media then it produces H2S (hydrogen sulfate). It causes the blackening of the media which acts as an indicator that bacteria can produce H2S.
2- Indol is the second characteristic. If bacteria is indol positive than it changes color from yellow to pink when the reagent is added.
3- Motility: if bacteria are motile than it's motility is easily visible in the media.
The scientists should conclude that other data must be considered in order to make a valid conclusion.
<h3>What is Archaefructus?</h3>
Archaefructus is an extinct genus of herbaceous aquatic seed plants with three known species. Fossil material assigned to this genus originates from the Yixian Formation in northeastern China, originally dated as late Jurassic but now thought to be approximately 125 million years old, or early Cretaceous in age.
Even with its revised age, Archaefructus has been proposed to be one of the earliest known genera of flowering plants.
Because of its age, lack of sepals and petals, and the fact that its reproductive organs (carpels and stamens), are produced on an elongate stem rather than condensed into a flower as in modern angiosperms,
Archaefructaceae has been proposed as a new basal angiosperm family.
An alternative interpretation of the same fossil, however, interprets the elongate stem as an inflorescence rather than a flower, with staminate (male) flowers below and pistillate (female) flower above.
