Answer: hydrogen

Problem: OPTIONS:
- physical transport
- impassive transport
- immune transport
- passive transport
Q: Answer the following question given this paragraph: Passive transport is a way that small molecules or ions move across the cell membrane without input of energy by the cell. The three main kinds of passive transport are diffusion (or simple diffusion), osmosis, and facilitated diffusion. Simple diffusion and osmosis do not involve transport proteins. Facilitated diffusion requires the assistance of proteins. Q: What term describes a way that small molecules or ions move across the cell membrane without input of energy by the cell? A:
Answer: passive transport

Problem:OPTIONS:
- stratosphere
- exosphere
- troposphere
- ionosphere

Answer the following question given this paragraph: A: With greater reflection off the ionosphere, AM waves can travel even farther at night than they can during the day. Radio receivers can often pick up radio broadcasts at night from cities that are hundreds of miles away. Q: Greater reflection off what atmospheric layer allows am radio waves to travel even farther at night than they can during the day? A:
****
A: ionosphere

Answer the following question given this paragraph: Following ventricular repolarization, the ventricles begin to relax, and pressure within the ventricles drops. When the pressure falls below that of the atria, blood moves from the atria into the ventricles, opening the atrioventricular valves and marking one complete heart cycle. 35 Afterload represents the resistance within the arteries to the flow of blood ejected from the ventricles. If uncompensated, if afterload increases, flow will decrease. In order for the heart to maintain adequate flow to overcome increasing afterload, it must pump more forcefully. This is one of the negative consequences of high blood pressure or hypertension. 37 After fusion of the two endocardial tubes into the single primitive heart, five regions quickly become visible. From the head, these are the truncus arteriosus, bulbus cordis, primitive ventricle, primitive atrium, and sinus venosus. Contractions propel the blood from the sinus venosus to the truncus arteriosus. About day 23, the heart begins to form an S-shaped structure within the pericardium. The bulbus cordis develops into the right ventricle, whereas the primitive ventricle becomes the left ventricle. The interventricular septum separating these begins to form about day 28. The atrioventricular valves form between weeks five to eight. At this point, the heart ventricles resemble the adult structure. Q: During fetal development of the heart, what does the bulbus cordis develop into? A:
OPTIONS:
- right atrium
- last ventricle
- left atrium
- right ventricle
right ventricle
