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? A:
****
A: blood shunts

Answer the following question given this paragraph: Mammals are very intelligent. Of all vertebrates, they are the animals that are most capable of learning. Mammalian offspring are fed and taken care of by their parents for a relatively long time. This gives them plenty of time to learn from their parents. By learning, they can benefit from the experiences of their elders. The ability to learn is the main reason that the large mammalian brain evolved. It's also the primary reason for the success of mammals. Q: Among vertebrates, what broad category of animals is most capable of learning? A:
OPTIONS:
- birds
- fish
- reptiles
- mammals
mammals

OPTIONS:
- epidermis
- chloroplasts
- chromosomes
- plasma membrane

Answer: plasma membrane

Q: Answer the following question given this paragraph: Macrophages are large WBCs that can also swallow and destroy old and dying cells, bacteria, or viruses. Below, a macrophage is attacking and swallowing two particles, possibly disease-causing pathogens ( Figure below ). Macrophages also release chemical messages that cause the number of WBCs to increase. Q: Macrophages, which can swallow and destroy old and dying cells, bacteria, or viruses, are large types of what cells? A:
Answer:
white blood cells
