Ques:Answer the following question given this paragraph: Eukaryotes have three different versions of the sexual life cycle : a haploid life cycle, a diploid life cycle, and a life cycle known as the alternation of generations ( Figure below ). A life cycle is the span in the life of an organism from one generation to the next. All species that reproduce sexually follow a basic pattern, alternating between haploid and diploid chromosome numbers. The sexual life cycle depends on when meiosis occurs and the type of cell that undergoes meiosis. Q: What is the term for the span in the life of an organism from one generation to the next? Choices: - time consumption - era - life span - life cycle A:

Ans:life cycle

Ques:Answer the following question given this paragraph: Fertilization Fertilization, pictured in Figure 43.23a 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. Q: In mammals what does the zona pellucida protect? Choices: - testes - sperm - fetus - egg A:

Ans:egg
