Meiosis I Prophase I: - nuclear membrane dissolves * centrioles move to poles * spindle fibres forming * DNA has been replicated and forms chromosomes made of 2 identical chromatids * Homologous chromosomes line up to form a bivalent‚ 2 chromosomes or 4 chromatids (TETRAD)‚ this process is called SYNAPSIS * Where chromatids overlap is called a CHIASMATA‚ and it allows for CROSSING OVER of genetic information between chromosomes Metaphase I: - homologous chromosomes

A concrete batching plant‚ also known as a concrete mixing plant‚ is a device that combines various ingredients to form large amount of concrete. It can have a variety of parts and accessories‚ including but not limited to: mixers‚ cement batchers‚ aggregate batchers‚ conveyors‚ radial stackers‚ aggregate bins‚ cement bins‚ heaters‚ chillers‚ cement silos‚ batch plant controls‚ and dust collectors (to minimize environmental pollution). Next‚ we will talk about how these accessories work together

There are four stages of sleep‚ stage 1 occurs when the person decides it’s time to fall asleep. Initially in stage 1 alpha waves start waxing and waning bursts of 8-12 Hz’s EEG. This is when we are alert at our wake fullness. Stage one sleep RRG is low voltage but high frequency signal. As the stages progress into stage 2 there’s a gradual increase in EEG voltage and decrease in EEG frequency. Stage 2 has a higher amplitude and lower frequency and also has two wave forms‚ k complexes and sleep spindles
