ethics will acknowledge that this is an incredibly controversial area‚ especially when considering the implications of this. For example‚ the right to a child for those who cannot naturally produce may incur or involve such procedures as IVF (in-vitro fertilisation) which remain controversial to many people still today. When looking to Kant’s ethics‚ we can see two main strands derive from his studies‚ nameably the Categorical Imperative and the Hypothetical imperative. With regards the Hypothetical Imperative

The son of Scottish migrants to Manitoba in the early 1900’s‚ Tommy Douglas grew up with a strong Christian underpinning of the ‘Protestant Work Ethic’ and the Christian ‘social gospel’ – a ‘belief that Christianity was above all a social religion‚ concerned as much with improving this world as with the life hereafter’. (Lovick and Marshall) These foundations initially led him to becoming a Baptist Minister in the small country town of Weyburn in Saskatchewan in 1930. However not quite 26 years

disables the sperm from reaching the ovum so fertilisation is not able to proceed‚ while abortion occurs when a new life ALREADY exists and this new life is being killed. Abortion is a ’solution’ for women who have been careless with sex‚ women who are not able to raise a child or women who have been raped. The Church labels abortion as a grave offence against God‚ since a creation of God is being destroyed. The foetus is actually a life‚ since fertilisation has occurred. Every human life has dignity

GENETICS JARGON Alleles (allelomorphs) Alternative forms of a particular gene. There can be several alleles of a particular gene in the population‚ but only 2 alleles can be inherited by a single individual. For simplicity much literature aimed at the general reader uses "gene" where it means "allele". Allelic Series A series of alleles that are all mutant forms of the same gene and are at the same locus (same position on the chromsome). Alternate Heredity Mendelian inheritance involving

embryonic stem-cells for scientific or medical research. This position has been taken as it has been widely reported that stem-cell research has the potential to treat several common diseases and save thousands of lives. The law under the Human Fertilisation and Embryology Act (1990) permits under strict controls the use of an embryo of up to 14 days for research purposes. However‚ the issue lies in the fact that it is impossible to agree with both moral attitudes in the case of embryonic stem cell

The availability of PGD‚ however‚ should not hinge on that fact‚ as the Human Fertilisation and Embryology Authority‚ in the UK‚ now requires.9 A couple that would coitally conceive a child to be a tissue donor should be free to use PGD to make sure that that child will be a suitable match‚ regardless of whether that child is also

Aquatic Adaptation Aquatic plants - also called hydrophytic plants orhydrophytes - are plants that have adapted to living in aquatic environments. -One of the main problems facing submerged aquatic plants is their inability to obtain oxygen. Unlike terrestrial plants‚ these plants cannot obtain the vital gas through their stomata because they are submerged in water. -Therefore‚ the stems‚ roots‚ and leaves of submerged aquatic plants posses aerenchyma cells‚ which supply oxygen to the rest of

It seems that the nitrogen‚ and phosphorus is coming from farm fields‚ and fertilisation.
