Q: 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:
A: hypoglycemia

Q: Answer the following question given this paragraph: Vertebrates. From the smallest of fish to us. One of the main features we all have in common is our backbone. Vertebrates describes main biological features of fish, amphibians, reptiles, birds, and mammals. Q: Vertebrates. from the smallest of fish to us. one of the main features we all have in common is our what? Choices: - hair - warm blood - laying eggs - backbone A:

Q: Answer the following question given this paragraph: because of interactions between the electrons of the outermost shell of different atoms, called the valence shell electrons. Electrons in inner shells are called core electrons. Elements are grouped together by similar chemical properties into a chart called the periodic table. Vertical columns of elements are called groups or families. Some of the groups of elements have names, like the alkali metals, the alkaline earth metals, the halogens, and the noble gases. A horizontal row of elements is called a period. Periods and groups have differing numbers of elements in them. The periodic table separates elements into metals, nonmetals, andsemimetals. The periodic table is also separated into main group elements,transition metals, lanthanide elements, and actinide elements. The lanthanide and actinide elements are also referred to as inner transition metal elements. The shape of the periodic table reflects the sequential filling of shells and subshells in atoms. The periodic table helps us understand trends in some of the properties of atoms. One such property is the atomic radius of atoms. From top to bottom of the periodic table, atoms get bigger because electrons are occupying larger and bigger shells. From left to right across the periodic table, electrons are filling the same shell but are being attracted by an increasing positive charge from the nucleus, and thus the atoms get smaller. Q: Electrons in inner shells are called what? Choices: - inner electrons - surface electrons - valence electrons - core electrons A:
A: core electrons

Q: Answer the following question given this paragraph: Figure 10.5 The cell cycle consists of interphase and the mitotic phase. During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase. During the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei. The cytoplasm is usually divided as well, resulting in two daughter cells. Q: What two phases does the cell cycle consist of? Choices: - antecedent and mitotic - mitosis and mitotic - outerphase and mitotic - interphase and mitotic A:
A: interphase and mitotic
