How does water reach the oceans

Often, water is carried into the ocean by the flow of rivers, this wave of movement is known as delta. At other times, groundwater can make its way to the ocean by seeping out of tiny cracks made. The final way water can reach its way to the ocean is when it rains, water droplets will fall onto the body of water, depending on the force of rain this can be a large addition to the ocean.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.

satellites are frequently used to make observations of the orbit on earth
