Pitch and Frequency are basically the same thing, but frequency can be quantified more easily. (Quantified is assigning a value). A piano may play a pitch of C, but the freque â¦ ncy could be 512 hertz.
Definition of speciesism. 1  1 : prejudice or discrimination based on species; especially : discrimination against animals. 2  2 : the assumption of human superiority on which speciesism is based.
A species is often defined as the largest group of organisms where two hybrids are capable of reproducing fertile offspring, typically using sexual reproduction. While in many cases this definition is adequate, the difficulty of defining species is known as the species problem.ractically, biologists define species as populations of organisms that have a high level of genetic similarity. This may reflect an adaptation to the same niche, and the transfer of genetic material from one individual to others, through a variety of possible means.
