Who Knows The Answer ?

Water consumption rises because suburban communities use  more water.

Explanation:

Urban sprawl can be described as a wide growth of the urban areas without proper planning. When such a large population starts to live in an urban area then the water consumption would be more. Even the construction process to support the urban sprawl will require adequate amounts of water. Hence, option C is correct.

Other options like option D id false because the usage of more water will lead to an increase in water consumption. The water consumption will not drop.

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.
