The metric system is a decimalized system of measurement used exclusively in the united states. a. true b. false

The correct answer is False

Explanation:

The metric system includes a set of decimalized units such as kilogram (Kg), meter (m) or second (s) used internationally to measure different variables such as weight, energy, time or distance. The purpose of this system is to guarantee all around the world people use the same units and therefore measurements can be understood and used by everyone. For example, in trade, a kilogram of cheese represents the same amount of cheese all around the world. According to this, it is false the metric system is used exclusively in the United States because the main purpose of this is that is used all around the world.

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.
