transport the pollen from the stamen to the pistil (Lambers 2014). An angiosperm ovule, located in the pistil, contains an egg cell and a diploid fusion nucleus, when pollen comes into contact with the top of the pistil it sends it down into the ovary at the pistil's base (Lambers 2014). As the pollen penetrates the ovule, it releases two sperm cells, one fuses with the egg to create a diploid zygote, while the other joins with the fusion nucleus to form a triploid nucleus (Lambers 2014). This triploid

A couple decades ago, when abortion was illegal, thousands of women died because they did not want to bear an infant and attempted to terminate the child's life by themselves or with an unprofessional approach. After 1973's Supreme Court decision, which allowed women to have the choice to abortion, thousands of women were saved. Abortion can save thousands of lives of women and thus, should remain legal in the United States. Imagine you have a balance beam. On one side you have the physical life

TOPIC “Designer Babies” Introduction We all know that designer babies are likely to become the 'thing' of the future. The rich will be able to change their child's eye color, hair color or possibly even how intelligent they are. Medicine will be able to advance to an all new high, with Downs syndrome, Huntiongton's disease and Tay-Sachs being all but distant memories. Designer babies Since the discovery of DNA in the late 1950's, the possibility of genetic modification of animals and plants

Hypogonadotropic hypogonadism Main article: Isolated hypogonadotropic hypogonadism Deficiency of sex hormones can result in defective primary or secondary sexual development, or withdrawal effects (e.g., premature menopause) in adults. Defective egg or sperm development results in infertility. The term hypogonadism is usually applied to permanent rather than transient or reversible defects, and usually implies deficiency of reproductive hormones, with or without fertility defects. The term is less

cell’s nucleus and are shaped from filaments of DNA. Genes (sections of DNA) are the elements in chromosomes. Each genetic code incorporates a special protein to the code. The proteins mobilize, monitor, and sustain your body. Indifference to human egg and sperm cells, dog offsprings are created through the mother’s dam chromosome and the father’s sire chromosome. Dog breeds are much more hereditarily differing in comparison to human races. There is a huge difference in size between different breeds of

the stages of meiosis in a plant were and which stages were present in a lily anther. The first generation of lily anther will always produce spores and then this grow and produce gametes, leading the male structure to produce sperm and the female structure to produce eggs. This process leads to the “transmission of traits” from one generation to another. We hypothesized that all the lily anther cells will be in the stages of Telophase I and Telophase II. We also predicted that if the cells were

aorta create a weak circulatory force. In fertilised queens the ovaries are activated when the queen lays her egg. It passes along the oviduct to the vagina. In the vagina there is a chamber called the spermatheca. This is where the queen stores sperm from her mating. The queen, depending on need, may allow her egg to be fertilised. Non-fertilised eggs become males, and only fertilised eggs grow into females and queens. As in all animals, hormones play a significant role in the growth and development

Hazelle Anne M. Garces BSA 2-23 Nutritional Requirements Eating is one of life’s pleasures. However, there is more to eating than sensory gratification. Food is needed to provide the nutrients required for the maintenance of normal structure and function of the body. Digestion can never serve its purpose without the body absorbing the nutrients it needs to maintain life. These nutrients however come in various types and forms and that an ideal amount of each should be taken to
