out some part of their arms to gather food. The mucus covered arms have tiny tube that flick edible bits into the pinnacle and arm. Reproduction Crinoids are dioecious‚ with separate male and female. They are producing their gametes from genital canals found inside some of the pinnules. The pinnules eventually rupture to release sperm and eggs into sea water. The fertilized eggs hatch to release a free swimming vitellaria larva. While both feeding and non-feeding larvae exist

Gregor Mendel 1. Who was Gregor Mendel? Mendel was a scientist who gained a substantial amount of fame from his study of genetics. He studied the pea plant and its inheritance of certain traits. 2. What contributions did he make to science? His study of genetics led to an increase interest in the study of genetics. His biggest contribution to the study of science was his discovery of particulate inheritance‚ dominant and recessive traits‚ genotype and phenotype‚ and the concept of

said Ovenden. Hybridization is common among many animal species‚ including some fish‚ but until now it has been unknown among sharks. In most fish species‚ fertilization takes place outside the body‚ with the males and females each releasing their gametes into the water where they mix. Blacktip sharks‚ by contrast‚ give birth to live young and actively choose their mates‚ which‚ as the scientists discovered‚ can sometimes be of a different species. Ovenden speculated that the two species began mating

Results: Somatic cells multiply through mitosis resulting in diploid‚ identical cells and meiosis provides for genetic variability along with haploid daughter cells‚ gametes‚ or sex cells. Most of the cells observed on the root tip were in interphase. Table 3.1 helped analyze the number of cells that are going through each phase of the cell cycle and helped estimate the amount of time it took for each cell to complete that phase. Table 3.2 compared and contrasted mitosis and meiosis. Conclusion:

that an unwitnessed oral exchange between husband and wife can be seen as formal consent to something as momentous as the posthumous creation of a child. Moreover‚ it can be argued that one simply cannot give valid consent to the extraction of one’s gametes for reproductive purposes after one falls permanently unconscious‚ or after one dies. (Compare the case of sexual acts performed on a person in a coma: morally‚ these would constitute rape of that person with or without prior consent to such acts
