Answer:
e. Cognitive Abilities
Explanation:
Based on the information provided it can be said that the influence on perception involved here is cognitive abilities. This refers to an individual's general mental capability which includes reasoning, problem solving, planning, abstract thinking, etc. In other words how well the individual is functioning. Cultural, Social Roles, and Age have nothing to do with this and Physiology focuses on the how different parts of an organism function.
For a long period of time, geneticists believed that one gene codes for one polypeptide. This hypothesis has been re-evaluated for two reasons. Firstly, some genes do not encode polypeptides, but functional RNA molecules. Secondly, due to the phenomenon of alternative splicing, some genes can encode several similar but not identical polypeptides. This phenomenon is present only in eukaryotes and it is based the fact that different parts of some genes can be used during gene expression.
Answer:
Trilobites
Explanation:
The Phanerozoic Eon is characterized by the presence of organisms that possessed hard shells as an adaptation to the environmental conditions. Among these organisms, the most common hard-shelled animals were the trilobites.
Trilobites were present during most of the Paleozoic Era, which belongs to the Phanerozoic Eon. These animals were marine organisms with remarkable and unique phenotypes.
The body of a trilobite was composed of three segments: the cephalon, the thorax, and the pygidium (tail). In addition, they possessed an exoskeleton composed of chitin, which was the reason behind their hard shells. They shed their exoskeletons to be able to grow.
Trilobites are currently extinct.
