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.

the discovery of new evidence
Explanation:
Accepted theories may be modified or overturned as new evidence and perspective emerges. Scientists are likely to accept a new or modified theory if it explains everything the old theory did and more. The process of theory change may take time and involve controversy, but eventually the scientific explanation that is more accurate will be accepted.

Answer:
A) Turkey feet grass
Explanation:
Grassland biome is one of the biomes that makes up the Earth's biosphere. Due to the characteristics of this biome (grassland), it favours the abundance of grass species over trees and shrubby plants. These characteristics include a low annual rainfall, soil's susceptibility to wind erosion etc.
Based on these characteristics, an organism that will thrive in this biome must be structurally adapted to it. This is the case of the Turkey feet grass mentioned in the question. The Turkey feet grass possess very deep roots to prevent soil loss in windy areas, and to help anchor the plant. This is as a result of soil loss common to the soil of grassland biomes.
