Mitochondria with extensive cristae are generally found in aerobic tissue cells that produce large quantities of ATP, such as muscle cells. Which of the following best describes how the increased amount of cristae in mitochondria leads to more efficient ATP production? The volume of the mitochondria matrix is increased.
The volume of the intermembrane space is increased.
The total number of ribosomes that synthesize ATP-producing protein complexes is increased.
The total number of main ATP-producing protein complexes on the inner mitochondrial membrane is increased.

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:

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
