Q: Answer the following question given this paragraph: You can see how Mendeleev organized the elements in the Figure below . From left to right across each row, elements are arranged by increasing atomic mass. Mendeleev discovered that if he placed eight elements in each row and then continued on to the next row, the columns of the table would contain elements with similar properties. He called the columns groups . They are sometimes called families, because elements within a group are similar but not identical to one another, like people in a family. Q: Mendeleev organized what basic units into rows and columns? A:
Answer: elements

Problem:OPTIONS:
- exothermic
- hydrostatic
- autotrophic
- endothermic

Answer the following question given this paragraph: Endothermic reactions absorb energy from the surroundings as the reaction occurs. When 1 mol of calcium carbonate decomposes into 1 mol of calcium oxide and 1 mol of carbon dioxide, 177.8 kJ of heat is absorbed. The process is shown visually in Figure above (B). The thermochemical reaction is shown below. Q: What kind of reactions absorb energy from their surroundings as they occur? A:
****
A: endothermic

Answer the following question given this paragraph: Mollusks have a circulatory system with one or two hearts that pump blood. The heart is a muscular organ that pumps blood through the circulatory system when its muscles contract. The circulatory system may be open or closed, depending on the species. Q: The heart is a muscular organ that pumps blood through which system? A:
OPTIONS:
- endocrine
- pulmonary
- nervous
- circulatory
circulatory

Answer the following question given this paragraph: 55.3 Energy transfer between trophic levels is typically only 10% efficient. Q: Energy transfer between what kinds of levels is generally rather inefficient? A:
OPTIONS:
- producer
- secondary
- apex
- trophic

Answer: trophic

Question: Answer the following question given this paragraph: Environmental scientists study the effects people have on their environment. This includes the landscape, atmosphere, water, and living things. These scientists ask all sorts of questions about how Earth systems are changing as a result of human actions. They try to predict what changes will come in the future. Q: What type of scientists study the effects people have on their environment? A:
OPTIONS:
- biological scientists
- ecological scientists
- integrated scientists
- environmental scientists
Answer: environmental scientists

input: OPTIONS:
- Maxillary sinus
- Sphenoid sinus
- Frontal sinus
- superior sagittal sinus Now, answer this question: Answer the following question given this paragraph: Venous Drainage of the Brain Circulation to the brain is both critical and complex (see Figure 20.37). Many smaller veins of the brain stem and the superficial veins of the cerebrum lead to larger vessels referred to as intracranial sinuses. These include the superior and inferior sagittal sinuses, straight sinus, cavernous sinuses, left and right sinuses, the petrosal sinuses, and the occipital sinuses. Ultimately, sinuses will lead back to either the inferior jugular vein or vertebral vein. Most of the veins on the superior surface of the cerebrum flow into the largest of the sinuses, the superior sagittal sinus. It is located midsagittally between the meningeal and periosteal layers of the dura mater within the falx cerebri and, at first glance in images or models, can be mistaken for the subarachnoid space. Most reabsorption of cerebrospinal fluid occurs via the chorionic villi (arachnoid granulations) into the superior sagittal sinus. Blood from most of the smaller vessels originating from the inferior cerebral veins flows into the great cerebral vein and into the straight sinus. Other cerebral veins and those from the eye socket flow into the cavernous sinus, which flows into the petrosal sinus and then into the internal jugular vein. The occipital sinus, sagittal sinus, and straight sinuses all flow into the left and right transverse sinuses near the lambdoid suture. The transverse sinuses in turn flow into the sigmoid sinuses that pass through the jugular foramen and into the internal jugular vein. The internal jugular vein flows parallel to the common carotid artery and is more or less its counterpart. It empties into the brachiocephalic vein. The veins draining the cervical vertebrae and the posterior surface of the skull, including some blood from the occipital sinus, flow into the vertebral veins. These parallel the vertebral arteries and travel through the transverse foramina of the cervical vertebrae. The vertebral veins also flow into the brachiocephalic veins. Table 20.13 summarizes the major... Q: What is the largest of the sinuses? A:
A:
output:
superior sagittal sinus
