century‚ development of ice harvesting and the insulated icehouse made ice more accessible to the general public. In the early 20th century ‚ electric power and mechanical refrigeration were brought by the industrialization that improved production. Nowadays ice-cream also offered by the upscale restaurant on their dessert lists. Making ice-cream goes through seven main processing stages. The seven stages are blending‚ pasteurizing‚ homogenizing‚ ageing‚ freezing‚ packaging and hardening.

New techniques for procreation include Artificial Insemination‚ Surrogacy and In-Vitro Fertilization‚ all which have brought about happiness to families. Unfortunately‚ at the same time many of these new reproductive techniques may bring about ethical considerations and debates‚ causing pain and legal arguments

and can be used to replace or even heal damaged tissues and cells in the body. Embryonic stem cells come from living‚ human embryos and can be harvested from two sources‚ embryos and fetuses. Embryonic stem cells are obtained by harvesting living embryos which are generally 5-7 days old. The removal of embryonic stem cells invariably results in the destruction of the embryo. Fetuses are another type of stem cell called an embryonic germ cell can be obtained from either miscarriages or aborted fetuses

A single sperm fertilizes the egg; the others are locked out. ’ (Time‚ 1997‚ pg. 66) Once the egg has been fertilized‚ cell division begins and the embryo drifts down the Fallopian tube. The embryo reaches the uterus in about a week. The embryo anchors itself to the wall of the uterus where it develops into a foetus. The foetus feeds off nutrients and oxygen provided by the placental lining in the uterus. There are several conditions in both

The issue of stem cells has led to controversy because embryos are generally used and they have to be destroyed for the cells to be used. However‚ a number of researchers believe thatstem cells will eventually change the face of medicine as we know it. Given the fact that the cells can be manipulated to mimic

Brief History of In Vitro Fertilization In Vitro Fertilization is a fertility procedure in which medical physicians remove eggs from the ovaries of a female‚ fertilize them in a laboratory‚ and then replace the embryos back into the female’s uterus where they implant and mature. In Vitro literally mean "in glass" meaning the Petri dishes that the eggs are placed into for fertilization. This procedure first came into place in England about 25 years ago by the late
