The results of Meiosis I are two diploid cells with genetic differences on the chromosome. These differences are a result of crossing-over. Crossing-over is a process that happens after both homologous chromosomes in a pair join up to form a structure called a tetrad. Tetrads form through a process called synapsis.
A tide is the periodic rising and falling of Earth's ocean surface caused mainly by the gravitational pull of the Moon acting on the oceans. Tides cause changes in the depth of marine and estuarine (river mouth) waters. Tides also make oscillating currents known as tidal streams (~'rip tides'). This means that being able to predict the tide is important for coastal navigation.
Red tides are caused by algal blooms. Certain types of algae in the ocean multiply at rapid rates, typically by excess nutrients found in the water. The algae die and the deca â¦ y process consumes the oxygen in the water -- one of the reasons these red tides are so destructive. By the way, not all algal blooms are red.
