Phases of meiosis on the lines provided, identify the stage of meiosis i or meiosis ii in which the event described occurs. 9. e
ach replicated chromosome pairs with its corresponding homologous chromosome. 10. crossing-over occurs between tetrads. 11. paired homologous chromosomes line up across the center of the cell. 12. spindle fibers pull each homologous chromosome pair toward an opposite end of the cell. 13. a nuclear membrane forms around each cluster of chromosomes and cytokinesis follows, forming two new cells. 14. chromosomes consist of two chromatids, but they do not pair to form tetrads. 15. a nuclear membrane forms around each cluster of chrom
Meiosis I Prophase I - homologous chromosomes form a tetrad, where they begin cross-over through the process of synapses. Metaphase - homologous chromosomes then align along the metaphase plate. Anaphase I - spindles then separate the homologous chromoses, pulling them to opposite poles of the cell Telephase I - the cell creates a cleavage burrow inwhich the cell divides into two new cells with 46 chromosomes in the process of cytokinesis
Meiosis II The same as mitosis Prophase II - Nuclear envelope disintegrates, Sister chromatids migrate towards the metaphase plate. Metaphase II - Sister chromatids align along the plate by their centromere. Anaphase II- spindles pull the chromatin to opposites poles Telephase II- cleavage burrow forms and cells seperate through cytokinesis
Plants are called producers. This is because they produce their own food! They do this by using light energy from the Sun, carbon dioxide from the air and water from the soil to produce food - in the form of glucouse/sugar.
The given compound is an alkane because all the bonds between carbon are single. Alkanes have all single bonds and are thus called saturated hydrocarbons.
Structuralism is widely regarded as the first school of thought in psychology. This outlook focused on breaking down mental processes into the most basic components. Major thinkers associated with structuralism include Wilhelm Wundt and Edward Titchener.
