Explanation:
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.
Answer:
cell nucleus has the most DNA
Answer: Meditation
Explanation: Meditation is an exercise where a person uses a method such as intentionally bringing one's awareness to encounters happening in the very period with no judgment or concentrating the psyche on a specific matter, reasoning or training. This is done to teach the mind the skill of the mental action of deeming or taking notice of somebody or something, and perception of reality or circumstance thereby attaining a mentally clear, emotionally quiet and firmly established condition.
