EXCRETION IN LOWER INVERTEBRATES
EXCRETION IN LOWER INVERTEBRATES :- Every organism possess different mechanisms, organs and different excretory product. For example porifera and hydra can perform excretion through body surface where as platyhelminthes possess a specialised cells known as flame cells. [...READ FULL]

ORGANS AND MECHANISM OF RESPIRATION IN HIGHER INVERTEBRATES
ORGANS AND MECHANISM OF RESPIRATION IN HIGHER INVERTEBRATES :- There are generally three common ways through which invertebrates can perform the process of respiration. These are cutaneous respiration which is mainly performed by lower invertebrates and annelids other is respiration through trachea and gills. [...READ FULL]
ADVANCED NERVOUS SYSTEM IN MOLLUSCA
Nervous system in mollusca has a well developed nervous system. It also bears paired ganglia, nerves and connectives. One important aspect is there that a Circumentric ring is formed by ganglia. A pair of cerebral ganglia (masses of nerve cell bodies) innervate the head, mouth, and associated sense organs. NERVOUS SYSTEM IN MOLLUSCA [...READ FULL]

Mean, median and mode all three are Central Tendency or Averages. The Arithmetic mean lies under Mathematical Average and the other two Median and Mode are types of Positional Averages. A measure of central tendency is a typical value around which the figures congregate". The value of central tendency or average always lies between the minimum and maximum values. [...READ FULL]
