brain and spinal cord
Answer the following question given this paragraph: Brain and spinal cord injuries most commonly occur because of car crashes or athletic activities. Fortunately, many injuries can be prevented by wearing seat belts and safety helmets (see Figure below ). Avoiding unnecessary risks, such as doing stunts on a bike or diving into shallow water, can also reduce the chances of brain and spinal cord injuries. Q: What are the two most common common ways that brain and spinal cord injuries occur? Choices: - falls and surgical error - sports and household accidents - car crashes and falls - car crashes and athletic activities A:
car crashes and athletic activities
Q: Answer the following question given this paragraph: None of your blood vessels are leaking this badly, or you'd be in the hospital! But your blood vessels do leak a little bit. Water and solutes pass out of the blood vessels and help form the fluid that bathes your body's tissues. Ultimately the fluid that is lost from the blood vessels is returned through the lymphatic system. Q: Ultimately, the fluid that is lost from the blood vessels is returned through what system? Choices: - symptomatic - venous - urinary - lymphatic A:
A: lymphatic
Question: Answer the following question given this paragraph: Yeasts are an exception. They reproduce asexually by budding instead of by producing spores. An offspring cell forms on a parent cell. After it grows and develops, it buds off to form a new cell. The offspring cell is genetically identical to the parent cell. You can see yeast cells budding in Figure below . Q: How do yeasts reproduce? Choices: - homosexual - preferentially - bisexual - asexually A:
Answer: asexually

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:
**Answer**
egg

Answer the following question given this paragraph: Purification of water for drinking and other uses is a complicated process. Heavy metals need to be removed, a process accomplished by addition of carbonates and sulfates. Lead contamination can present major health problems, especially for younger children. Lead sulfates and carbonates are very insoluble, so will precipitate out of solution very easily. Q: Is purifying water a simple or complicated process? Choices: - expensive - impossible - simple - complicated A:
**Answer**
complicated
