This map shows the age of the Atlantic oceans oceanic crust. What does the curving band of red that goes from the top of the map to the bottom indicate

The red curved line in the map provided is the Mid-Oceanic ridge (MOR), which is here known as the Mid-Atlantic ridge, and is the result of the divergent plate boundary where the two plates move away from each other in the opposite direction

Explanation:

D. A divergent plate boundary in the middle of the ocean.

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.
