.... The spore germinates and grows into a prothallus which is the gametophyte generation. The antheridia and the archegonia are developed on the bottom of the prothallus. The archegonia are at the notch of the prothallus and the antheridia are located near the tip. Fertilization occurs when outside moisture is present and the sperm from the antheridia swim to the eggs of the archegonia. A zygote is formed on the prothallus and a new sporophyte grows. 4. Flowering plants have unique characteristics that help them survive. One is the flower itself that .....

.... acid being formed. Lactic acid is a waste product of anaerobic cellular respiration within the muscle tissue, which can cause muscle sourness that, usually, is felt after a hard or long workout. Fatigue usually sets in with the onset of lactic acid production. Oxygen is carried to the muscle by two delivery systems. Three percent of oxygen is carried in plasma and ninety-seven percent is in hemoglobin, the principal protein in erythrocytes (red blood cells). If hemoglobin amounts are increased, this will lead to increased oxygen levels that can be transp .....

.... uterus where it will call home for the next nine months. After about two days it has divided to having about eight cells. After four days it is in the uterus and has to "land" somewhere and attach itself to the endometrium. The eighth day is when implantation occurs. The fertilized egg then implants itself on the endometrium, the uterine lining, and begins to grow. The cell begins to grow and develop. By the 12th day the blastocyst has approximately two thousand cells in it. It has had time to attach itself to the endometrium and these anchors .....

.... current tests are time consuming and technically difficult to do, are restricted to women over 35 and those who have a family history of chromosomal abnormalities. Prenatal tests using Willard's probes would be much simpler and faster to perform and could be available to all pregnant women who wish to take advantage of the technology. Current prenatal testing involves growing fetal cells in vitro and examining them, over one or two months, to see if there are two copies of a particular chromosome, which is normal, or one or three, which is abnormal. A test us .....

.... p 3). Whatever the reason of belief or disbelief in Darwin's theories, he astounded the scientific world as well as the public and was able to convince many in the presence of a misguided past belief. This fact alone makes him one of the most important people of science ever. Charles Darwin was born in Shrewsbury-Shropshire, England on Feb 12, 1809 (GEA & RBi p 42). He was the fifth child in a wealthy English family with a history of scientific achievement with his paternal grandfather Erasmus Darwin who was a physician and a savant in the eighteenth centu .....

.... and animation industry is still in its infancy. The future looks bright. How It Was In the beginning, computer graphics were as cumbersome and as hard to control as dinosaurs must have been in their own time. Like dinosaurs, the hardware systems, or muscles, of early computer graphics were huge and ungainly. The machines often filled entire buildings. Also like dinosaurs, the software programs or brains of computer graphics were hopelessly underdeveloped. Fortunately for the visual arts, the evolution of both brains and brawn of computer graphics di .....

.... impacts of acid precipitation is on forests and soils. A lot of damages are being done when the sulphuric acid falls onto the earth as rain. All the nutrients in the soils are washed away making it hard for some plants to grow. The presence of nitrogen oxide and nitric oxide also can force trees to grow even though they do not have the necessary nutrients. The trees are sometimes forced to grow during late autumn when it is actually the time for them to prepare for severe winter weather. One of the direct effects of acid rain is on lakes and the whole .....
