Schizophrenia is a mental disorder defined as chronic and severely debilitating as the patients usually are "lost in touch with reality."
Schizophrenia has both positive symptoms (added) and negative symptoms (lack of). Positive symptoms include hallucinations (<em>adding </em>unreal imagery) and uncontrollable thoughts. Negative symptoms include apathy <em />(<em>lack of </em>concern or enthusiasm), alogia (<em>lack of </em>speech), and blunted affect (<em>lack of </em>facial expression). Both positive and negative symptoms affect the intellectual functioning of an individual with schizophrenia.
Mitosis goes in the order of PMAT, or Prophase, Metaphase, Anaphase, and Telophase.
Prophase is when the nuclear envelope breaks down and the chromosomes are visible. Metaphase is when the chromosomes line up in the middle. Anaphase is when the spindle fibers pull the centromeres apart. Telophase is when the chromosomes go to the opposite sides and the nuclear envelope reappears.
Los seres invertebrados y los vertebrados tienen más elementos en común de lo que se pensaba. Un estudio, con participación del Consejo Superior de Investigaciones Científicas (CSIC), prueba que existe gran similitud entre los sistemas excretores de ambos grupos de animales. Según la investigación, las células encargadas de filtrar la sangre en la formación de orina, alojadas en los riñones de vertebrados, son similares a las que realizan una función análoga en invertebrados.
