under 10x magnification. The spores have germinated and has begun to develop into a young gametophytes. After water was inserted onto the petri dish, tiny particles appeared to be “swimming”. These particles are sperm, indicating that water was needed to facilitate the fertilization of the eggs. This indicates that the organism could be part of either the Bryophyta or the Pterophyta division. The root like structures, rhizomes, which indicates that this organism has vascular tissue, were sticking out

helps to keep the tips of chromosomes (telomeres) in tact. * How do people get Cri-du-Chat syndrome? * A deletion is caused by a break in the DNA molecule that makes up a chromosome. In most cases, the chromosome break occurs while the sperm or egg cell (the male or female gamete) is developing. When this gamete is fertilized, the child will

develop and help the uterus to get thick and to get prepared for the fertilization of an egg. Each egg leaves the woman’s ovaries and it goes into the fallopian tube, then after this process it gets travelled through to the uterus. It all starts during intercourse, when a man has intercourse with a woman he inserts sperm into her vagina about 250 million sperms would have been ejaculated into the vagina. Every sperm looks the same as it has a long tall to enable it to swim and force itself up to the

Certainly the issue of abortion is not something to be taken lightly because it is the termination of what could, potentially, become a human being. There are very many ways of looking at abortion, which make it hard to decide whether or not you are for it. Although there are many good reasons as to why someone would choose to be against it I, for one, believe abortion could, in some cases, be the right thing to do. Abortion could save women from an experience that could either damage or kill them

A slug will endeavor to locate a mate, encircle each other and sperm is then exchanged through their genitalia which is protruded. It will then take a few days for the slugs to lay approximately thirty eggs in a hole in the ground, or beneath the cover of an object such as a fallen log. These eggs are gelatinous and spherical in shape. They measure approx. 1/8 to ¼ inch in diameter and are either golden or white in color. The eggs will hatch within 10 days. Slugs even have the ability to reproduce

Imagine a world full of “Mini-Hitlers”, genetic replicates of Adolf Hitler, seeking world domination. Picture them starting a second Holocaust on a worldwide scale, killing millions upon millions of people as a “final solution” to establish a superior race. This scenario is far-fetched, but this is the kind of thing people think about when they hear the word “cloning”. Cloning has frequently surfaced within the media, and continues to garner attention. For example, the movie Jurassic Park features

sexually. the sperm and the egg of two separate medusae produce a zygote.. The zygote turns into a planula (larva). The planula larva abandons the adult medusae. It then finds a shaded surface and adheres itself to it. The planula ultimately grows into a new polyp, and the life cycle of the Aurelia aurita begins once again. Adult flukes deliver eggs in the biliary ducts of their hosts. The ducts transfer bile from the liver and gallbladder through the pancreas to the small intestine. The eggs arrive in

disease prior to implanting of the embryos. Only a handful of scientic in the world are capable of deciphering the genetic makeup of an embryo. To examine the embryos, first the women most go through In Vitro Fertilization (I.V.F), I.V.F is mixing sperm and egg in a petri dish to create multiple embryo. Next scientists can perform a P.G.D on the embryos. With P.G.D a scientific breakthrough happened scientists could now see the sex of the embryos instead of waiting the normal 16-20 weeks to know the sex
