Answer the following question given this paragraph: This animation (http://openstaxcollege. org/l/insulin) describe the role of insulin and the pancreas in diabetes. Impaired insulin function can lead to a condition called diabetes mellitus, the main symptoms of which are illustrated in Figure 37.10. This can be caused by low levels of insulin production by the beta cells of the pancreas, or by reduced sensitivity of tissue cells to insulin. This prevents glucose from being absorbed by cells, causing high levels of blood glucose, or hyperglycemia (high sugar). High blood glucose levels make it difficult for the kidneys to recover all the glucose from nascent urine, resulting in glucose being lost in urine. High glucose levels also result in less water being reabsorbed by the kidneys, causing high amounts of urine to be produced; this may result in dehydration. Over time, high blood glucose levels can cause nerve damage to the eyes and peripheral body tissues, as well as damage to the kidneys and cardiovascular system. Oversecretion of insulin can cause hypoglycemia, low blood glucose levels. This causes insufficient glucose availability to cells, often leading to muscle weakness, and can sometimes cause unconsciousness or death if left untreated. Q: Oversecretion of insulin can cause what? Choices: - hyperglycemia - inflammation - hypoxia - hypoglycemia A:
hypoglycemia
Answer the following question given this paragraph: Algae play significant roles as producers in aquatic ecosystems. Microscopic forms live suspended in the water column. They are the main component of phytoplankton. As such, they contribute to the food base of most marine ecosystems. Q: What is the main component of phytoplankton? Choices: - amoebas - seawater - cells - algae A:
algae
Q: Answer the following question given this paragraph: Primary Batteries Primary batteries are single-use batteries because they cannot be recharged. A common primary battery is the dry cell (Figure 17.10). The dry cell is a zinc-carbon battery. The zinc can serves as both a container and the negative electrode. The positive electrode is a rod made of carbon that is surrounded by a paste of manganese(IV) oxide, zinc chloride, ammonium chloride, carbon powder, and a small amount of water. The reaction at the anode can be represented as the ordinary oxidation of zinc: Zn(s) Zn 2+(aq) + 2e . Q: Primary batteries are single-use batteries because they cannot be what? Choices: - UP ticked. - refreshed - plugged - recharged A:
A: recharged
Question: Answer the following question given this paragraph: Matter is anything that has mass and takes up space. Matter is everywhere. The air we breathe, the water we drink, the food we eat, and the ground we walk on are all comprised of matter. Matter can take on a variety of different forms which all have a variety of different properties. In this chapter, we will introduce the characteristics of matter and study how these characteristics vary in different types of matter. Q: Anything that has mass and takes up space is considered what? Choices: - energy - light - power - matter A:
Answer: matter

Answer the following question given this paragraph: Soil type also influences the type of vegetation that can grow in the region. We can identify climate types by the types of plants that grow there. Q: Along with climate, this also influences the type of vegetation that can grow in the region? Choices: - gravity - fertilizer use - population density - soil type A:
**Answer**
soil type
