Answer the following question given this paragraph: Regulation of Blood Glucose Levels by Insulin and Glucagon Glucose is required for cellular respiration and is the preferred fuel for all body cells. The body derives glucose from the breakdown of the carbohydrate-containing foods and drinks we consume. Glucose not immediately taken up by cells for fuel can be stored by the liver and muscles as glycogen, or converted to triglycerides and stored in the adipose tissue. Hormones regulate both the storage and the utilization of glucose as required. Receptors located in the pancreas sense blood glucose levels, and subsequently the pancreatic cells secrete glucagon or insulin to maintain normal levels. Q: What does the body derive from the breakdown of the carbohydrate-containing foods and drinks we consume? A:
****
A: glucose

Answer the following question given this paragraph: The stability of an ecosystem depends on the actions of the decomposers. Examples of decomposers include mushrooms on a decaying log. Bacteria in the soil are also decomposers. Imagine what would happen if there were no decomposers. Wastes and the remains of dead organisms would pile up and the nutrients within the waste and dead organisms would not be released back into the ecosystem. Producers would not have enough nutrients. The carbon and nitrogen necessary to build organic compounds, and then cells, allowing an organism to grow, would be insufficient. Other nutrients necessary for an organism to function properly would also not be sufficient. Essentially, many organisms could not exist. Q: The stability of an ecosystem depends on the actions of what, exemplified by mushrooms on a decaying log and bacteria in soil? A:
OPTIONS:
- whitefly
- fluxes
- aphids
- decomposers
decomposers

Answer the following question given this paragraph: Many animals have a relatively simple life cycle. A general animal life cycle is shown in Figure below . Most animals spend the majority of their life as diploid organisms. Just about all animals reproduce sexually. Diploid adults undergo meiosis to produce sperm or eggs. Fertilization occurs when a sperm and an egg fuse. The zygote that forms develops into an embryo. The embryo eventually develops into an adult. Q: What causes fertilization to occur? A:
OPTIONS:
- accumulation and an egg fuse
- tissue and an egg fuse
- genetic and an egg fuse
- sperm and an egg fuse

Answer:
sperm and an egg fuse
