Q: What field of science seeks to explain how traits are passed on from one generation to the next? Choices: - zoology - biochemistry - quantum physics - genetics A:

Question: Answer the following question given this paragraph: Scientists refer to the vertical extent of ocean water as the water column . Two main zones based on depth of water are the photic zone and aphotic zone. The photic zone is the top 200 meters of water. The aphotic zone is water deeper than 200 meters. The deeper you go, the darker the water gets. That's because sunlight cannot penetrate very far under water. Sunlight is needed for photosynthesis. So the depth of water determines whether photosynthesis is possible. There is enough sunlight for photosynthesis only in the photic zone. Q: What is the vertical extent of ocean water called? Choices: - oceanic pillar - ocean column - water row - water column A:
Answer: water column

Answer the following question given this paragraph: All modern classification systems have their roots in the Linnaean classification system. It was developed by Swedish botanist Carolus Linnaeus in the 1700s. He tried to classify all living things that were known at his time. He grouped together organisms that shared obvious physical traits, such as number of legs or shape of leaves. For his contribution, Linnaeus is known as the "father of taxonomy. " You can learn more about Linnaeus and his system of classification by watching the video at this link: http://teachertube. com/viewVideo. php?video_id=169889 . Q: What classification system was developed by a swedish botanist trying to classify all known living things? Choices: - taxonomical system - plantological system - bionumerical system - linnaean system A:
**Answer**
linnaean system

Answer the following question given this paragraph: The five regions of the primitive heart tube develop into recognizable structures in a fully developed heart. The truncus arteriosus will eventually divide and give rise to the ascending aorta and pulmonary trunk. The bulbus cordis develops into the right ventricle. The primitive ventricle forms the left ventricle. The primitive atrium becomes the anterior portions of both the right and left atria, and the two auricles. The sinus venosus develops into the posterior portion of the right atrium, the SA node, and the coronary sinus. As the primitive heart tube elongates, it begins to fold within the pericardium, eventually forming an S shape, which places the chambers and major vessels into an alignment similar to the adult heart. This process occurs between days 23 and 28. The remainder of the heart development pattern includes development of septa and valves, and remodeling of the actual chambers. Partitioning of the atria and ventricles by the interatrial septum, interventricular septum, and atrioventricular septum is complete by the end of the fifth week, although the fetal blood shunts remain until birth or shortly after. The atrioventricular valves form between weeks five and eight, and the semilunar valves form between weeks five and nine. Q: Although much of the heart's basic structure is complete by the end of the fifth week, what fetal structures remain until birth or shortly after? Choices: - heart shunts - renal arteries - umbilical arteries - blood shunts A:
(Answer)
blood shunts
