It consists of four folded chains of a protein called globin, designated alpha 1 and 2, and beta 1 and 2 (Figure 18.7a). Each of these globin molecules is bound to a red pigment molecule called heme, which contains an ion of iron (Fe2+) (Figure 18.7b). Q: Hemoglobin is a large molecule made up of proteins and iron. it consists of four folded chains of a protein called this? A:
A:
output: globin

Answer the following question given this paragraph: Homeostasis refers to the balance, or equilibrium within the cell or a body. It is an organism's ability to keep a constant internal environment. Keeping a stable internal environment requires constant adjustments as conditions change inside and outside the cell. The adjusting of systems within a cell is called homeostatic regulation. Because the internal and external environments of a cell are constantly changing, adjustments must be made continuously to stay at or near the set point (the normal level or range). Homeostasis is a dynamic equilibrium rather than an unchanging state. The cellular processes discussed in this lesson all play an important role in homeostatic regulation. More concerning homeostasis will be presented in additional concepts. Q: What is the name of the process that refers to the balance or equilibrium within the cell or a body? A:

OPTIONS:
- static
- hypothesis
- determinants
- homeostasis

Answer: homeostasis

Problem: OPTIONS:
- velocity
- momentum
- freezing
- stretching or compressing
Q: Answer the following question given this paragraph: Springs like the ones in Figure below also have elastic force when they are stretched or compressed. And like stretchy materials, they return to their original shape when the stretching or compressing force is released. Because of these properties, springs are used in scales to measure weight. They also cushion the ride in a car and provide springy support beneath a mattress. Can you think of other uses of springs?. Q: What causes an elastic force in springs? A:
Answer: stretching or compressing

Answer the following question given this paragraph: Scientists are searching for ways to create controlled nuclear fusion reactions on Earth. Their goal is develop nuclear fusion power plants, where the energy from fusion of hydrogen nuclei can be converted to electricity. You can see how this might work in the Figure below . In the thermonuclear reactor, radiation from fusion is used to heat water and produce steam. The steam can then be used to turn a turbine and generate electricity. Q: What drives the turbine in a thermonuclear reactor? A:
****
A:
heated water or steam
