There are some certain points when discussing about living and non-living things. They are mostly specific on living things such as cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development and adaption through evolution. Things which have these characteristics

single orifice which functions as both the mouth and anus (Steinbach, 1962). They are usually hermaphroditic species that are able to reproduce both sexually and asexually. Sexual reproduction occurs by exchanging the gametes between two separate organisms. The planaria usually divides into half during asexual reproduction, and regenerates the missing body parts. This

living organisms. In humans, there is an X chromosome and a Y chromosome that determines the sex of the offspring. A male has an X and Y chromosome, whereas a female has two X chromosomes. The sex of an offspring is determined by whether the sperm cell that fertilizes the egg is made up of an X or a Y chromosome; ultimately the male is the determining factor of the sex of the offspring. Even though the Y chromosome determines if the offspring will be male, the X chromosome has genes that control

Snap! Sperm cell Sexual reproduction occurs when offspring result from the joining (fusion) of a male reproductive cell and a female reproductive cell. These special reproductive cells are called gametes and are made in the reproductive organs of organisms. In animals, male gametes are called sperm and female gametes are called ova (singular = ovum) or egg cells. Reproductive systems are designed to bring the male and female gametes together. The joining of sperm and egg cells is called fertilisation

My project involved the observation of planarian . My primary question concerned the impact that magnesium chloride played on the regrowth and/or reproduction process of planarian. * Before I began my research I was not very knowledgeable about the subject or these organisms. * From previous experiments too much chloride caused the cell to dry up. * My first reference was an abstract based on an experiment by Wolfgang Schurmann and Roland Peter. Their findings led me to believe

Reproduction is a means of a species’ survival. Over time, having children has become viewed as a gift and a very special occasion that only happens a few times in one’s life, not just a means of survival. The idea of reproduction and what it means and does for society has become increasingly important. Everything an expectant mother eats, drinks, and puts into her body goes directly into her fetus’ bloodstream. The actions a mother takes during pregnancy sets the course of her baby’s entire life

nervous system does the opposite decreasing heart rate. Both systems work together to regulate involuntary bodily functions and behaviors. One example of regulatory behavior is human reproduction and sexuality, and sexuality leads to reproduction in order for humans to reproduce and pass on genes. Sexual reproduction enables evolutionary adaptations and corrects errors. Two parents that both carry disadvantageous genes can have a child that then carries

Basic Processes SCI/230 January 30, 2012 Reproduction Germs reproduce asexually by using a method called binary fission in the prokaryotic cells and in mitosis. Germs split into two different creatures within the colony each cell exist apart from the other. Grasshoppers reproduce by copulating end to end and insert its aedeagus into the ovipositor to deliver his sperm. They reproduce by laying eggs, which are fertilized within the female grasshopper. The eggs contain a yoke for
