nuclear membrane disintegrates. Chromosomes join at points called chiasmata where crossing over takes place. Metaphase I The nuclear membrane completely disappears. Spindle fibres attach to the chromosome’s centromeres and homologous pairs move together and line up along the metaphase plate. Anaphase I Spindle fibres pull homologous chromosomes towards opposite poles of the cell. This separates the chromosomes into two haploid set. Telophase I The homologous chromosomes arrive at there

evolved through the introduction of modern technology and knowledge on certain events. In modern times the perfect crime is almost impossible to commit as a direct result of hair fibres. In order to commit a perfect crime every hair fibre would have to be removed (Mr Sanchez‚ 2011). This essay explores the importance of hair fibres in forensic science and strives to grasp concepts of such a field. Aim The aim of this investigation was to closely examine three different hair types and reflect on the similarities

In this essay I will include information regarding: cell differentiation‚ the functions of various cell organelles‚ tissues and a comparison of different tissue types. Cellular differentiation is the process by which a less specialised cell becomes a more specialised cell type. Differentiation happens a number of times during the development of a multicellular organism as

spiral turns given to yarn in order to hold the fibres or threads together. Twist is necessary to give a yarn coherence and strength. Twist is primarily instructed in to a staple yarn in order to hold the constituent fibres together‚ thus giving strength to the yarn. False twist is used in textured yarns. The effects of the twist are twofold: As the twist increases‚ the lateral force holding the fibres together is increased so that more of the fibres are contributed to the overall strength of the

Silkworm larvae are fed mulberry leaves‚ and‚ after the fourth moult‚ climb a twig placed near them and spin their silken cocoons. This process is achieved by the worm through a dense fluid secreted from its gland structural glands‚ resulting in the fibre of the cocoon. The silk is a continuous-filament fiber consisting of fibroin protein‚ secreted from two salivary glands in the head of each larva‚ and a gum called sericin‚ which cements the two filaments together. The sericin is removed by placing

Connective Tissue As the name implies‚ connective tissue serves a "connecting" function. It supports and binds other tissues. Unlike epithelial tissue‚ connective tissue typically has cells scattered throughout an extracellular matrix. Loose Connective Tissue In vertebrates‚ the most common type of connective tissue is loose connective tissue. It holds organs in place and attaches epithelial tissue to other underlying tissues. Loose connective tissue is named based on the "weave" and type
