Answer: Ptolemaic system, also called geocentric system or geocentric model, mathematical model of the universe formulated by the Alexandrian astronomer and mathematician Ptolemy about 150 CE and recorded by him in his Almagest and Planetary Hypotheses. The Ptolemaic system is a geocentric cosmology; that is, it starts by assuming that Earth is stationary and at the centre of the universe. The “natural” expectation for ancient societies was that the heavenly bodies (Sun, Moon, planets, and stars) must travel in uniform motion along the most “perfect” path possible, a circle. However, the paths of the Sun, Moon, and planets as observed from Earth are not circular. Ptolemy’s model explained this “imperfection” by postulating that the apparently irregular movements were a combination of several regular circular motions seen in perspective from a stationary Earth.

Answer:
Species
Explanation:
Species is the most specific and basic taxonomic level of classification and also the basic unit of biodiversity. Species is defined as group of highly closely related organisms that mate or breed to produce fertile offspring. After species genus is specific, and mostly organisms names are identified by species names and genus names as in binomial nomenclature, all scientific names are derived from genus and species e.g. the scientific name of frog is <em>Rana tigrina, </em>here '<em>Rana</em>' is genus name that is always capitalized and '<em>tigrena</em>' is species name that starts with small letter but both are always written in italics or underlined.
Answer;
Seedless plant.
The fossil of a plant reveals that it produced spores that were used for reproduction. It was a seedless plant.
Explanation;
-Seedless vascular plants are plants such as fern and horsetails, liverworts, mosses; which contain vascular tissues, but do not produce flowers or seed.
-These plants reproduce using haploid , unicellular spores instead of seeds.
-These plants have life cycles with two distinct stages; one in which spores are produced and one in which sex cells are produced.
