A short chain of the cyanobacterial cells found in the Bitter Springs Chert in northern Australia (about 1 billion years old). The bulk of modern genera really resemble cyanobacteria that are closely related to those that are living today. Unlike this fossilized cyanobacterium.
The fact that microorganisms can even leave fossils may surprise you. The oldest cyanobacteria-like fossils, which are among the oldest fossils ever found, are from the Precambrian, but one specific type of bacterium, the cyanobacteria or "blue-green algae," has left a fossil record that extends all the way back to that time. Larger than other bacteria, cyanobacteria have the ability to produce a thick cell wall. More crucially, cyanobacteria have the ability to form enormous, layered structures known as stromatolites or oncolites, depending on whether or not they resemble domes (if round).

Chemical bonds.
Chemical bonds hold the atoms of a molecule together thereby forming covalent bonds, when two atoms share electrons.
<h2>Gametophyte and Sporophyte Generations</h2>
Explanation:
- <em>The sexual stage, called the gametophyte generation,</em> produces gametes, or <em>sex cells, and the abiogenetic stage, or sporophyte age, </em>produces spores abiogenetically
- As far as chromosomes, the <em>gametophyte is haploid</em> (has a solitary arrangement of chromosomes), and the <em>sporophyte is diploid (has a double set)</em>
- All aquatic plants have alternation of generations. In mosses and their <em>family members (Bryophytes), the haploid gametophyte is the predominant age,</em> and the diploid sporophytes are sporangium-bearing stalks developing from the gametophytes
If the image shows a hand nurturing a plant, with the purpose to persuade people to take care of Earth, this is a visual example of C. rhetoric, or to be more precise, visual rhetoric.
Rhetoric is used with one purpose mostly - to persuade. So this would be the correct answer.
Semiotics is simply the study of meaning, whereas logos visual are just logos.
