Ques:Answer the following question given this paragraph: You must have a GPS receiver to use the system. You can buy many types of these in stores. The GPS receiver detects radio signals from nearby GPS satellites. There are precise clocks on each satellite and in the receiver. The receiver measures the time for radio signals from satellites to reach it. The receiver uses the time and the speed of radio signals to calculate the distance between the receiver and the satellite. The receiver does this with at least four different satellites to locate its position on the Earth's surface ( Figure above ). GPS receivers are now being built into many items, such as cell phones and cars. Q: What do we call the worldwide radio-navigation system formed from a constellation of 24 satellites and their ground stations? Choices: - cellular network - radio waves - compass - gps A:

Ans:gps

Ques:Answer the following question given this paragraph: affect the rate of diffusion, including concentration gradient, size of the particles that are diffusing, temperature of the system, and so on. In living systems, diffusion of substances into and out of cells is mediated by the plasma membrane. Some materials diffuse readily through the membrane, but others are hindered, and their passage is made possible by specialized proteins, such as channels and transporters. The chemistry of living things occurs in aqueous solutions, and balancing the concentrations of those solutions is an ongoing problem. In living systems, diffusion of some substances would be slow or difficult without membrane proteins that facilitate transport. Q: In living systems, diffusion of substances into and out of cells is mediated by the what membrane? Choices: - gas - fluid - ferment - plasma A:

Ans:plasma
