A carbohydrate that yields many monosaccharides when hydrolyzed is a disaccharide . 2. A simple sugar is composed of equal parts carbon and water, which gave rise to the general name of any sugar as a carbohydrate . 3. Lactose, the sugar in milk, is a monosaccharide, because it can be split into two monosaccharides. 4. A polysaccharide cannot be hydrolyzed any further.

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.

explanation:

mammal

explanation:

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.

straight probes are used primarily for measuring flow as it is approaching the test area. its geometry allows the probe to be mounted so that it is in the direct line of airflow.
