Answer the following question given this paragraph: Figure 19.4 Dual System of the Human Blood Circulation Blood flows from the right atrium to the right ventricle, where it is pumped into the pulmonary circuit. The blood in the pulmonary artery branches is low in oxygen but relatively high in carbon dioxide. Gas exchange occurs in the pulmonary capillaries (oxygen into the blood, carbon dioxide out), and blood high in oxygen and low in carbon dioxide is returned to the left atrium. From here, blood enters the left ventricle, which pumps it into the systemic circuit. Following exchange in the systemic capillaries (oxygen and nutrients out of the capillaries and carbon dioxide and wastes in), blood returns to the right atrium and the cycle is repeated. Q: Blood flows from the right atrium to the right ventricle, where it is pumped into the what? Choices: - bronchial circulation - respiratory system - kidneys - pulmonary circuit A:
pulmonary circuit
Q: Answer the following question given this paragraph: After leaves turn color in the fall, they may all fall off the plant for the winter. Plants that shed their leaves seasonally each year are called deciduous plants . Shedding leaves is a strategy for reducing water loss during seasons of extreme dryness. On the downside, the plant must grow new leaves in the spring, and that takes a lot of energy and matter. Some plants may "bank" energy over the winter by storing food. That way, they are ready to grow new leaves as soon as spring arrives. Q: What do we call plants that shed their leaves seasonally each year? Choices: - perennials - annuals - lush plants - deciduous plants A:
A: deciduous plants
Question: Answer the following question given this paragraph: During anaphase I the spindle fibers shorten, and the homologous chromosome pairs are separated from each other. This occurs as the chiasmata are severed, pulling homologous chromosomes apart. One chromosome from each pair moves toward one pole, with the other moving toward the other pole, resulting in a cell with 23 chromosomes at one pole and the other 23 at the other pole. Each chromosome still contains a pair of sister chromatids; the sister chromatids remain attached at the centromere. Q: How many pairs of chromosomes are there? Choices: - 16 - 25 - 24 - 23 A:
Answer: 23
*Question*
Answer the following question given this paragraph: Plants and animals exist in a cycle; each requires products of the other. The thousands of coordinated chemical reactions that keep cells alive are referred to collectively as metabolism. In general, metabolic reactions are divided into two classes: the breaking down of molecules to obtain energy is catabolism, and the building of new molecules needed by living systems is anabolism. Q: What is the term for the metabolic reaction where living systems build new molecules? Choices: - symbolism - connectionism - metabolism - anabolism A:
**Answer**
anabolism
Answer the following question given this paragraph: Air pollution consists of chemical substances and particles released into the air, mainly by human actions. The major cause of outdoor air pollution is the burning of fossil fuels. Indoor air can also be polluted. Air pollution, in turn, causes acid rain, ozone depletion, and global warming. Q: What causes acid rain, ozone depletion, and global warming? Choices: - ozone layer - water pollution - radiation - air pollution A:
air pollution
