B. an extended period of time with little to no snow or rainfall

Explanation:

Drought is a natural calamity which occur in a region which receives low precipitation or the precipitation may be absent. This result in hot and dry climatic conditions. The drought is responsible for occurrence of desert like conditions such as soil becomes compact or loose, soil losses it's fertility, drying up of natural source of water and tree growth is scanty.

On the basis of the above explanation, B. an extended period of time with little to no snow or rainfall is the correct option.

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.
