Read this paragraph and choose the correct option from the provided answers: Vertebrates reproduce sexually, and almost all of them have separate male and female sexes. Generally, aquatic species have external fertilization, whereas terrestrial species have internal fertilization. Can you think of a reason why aquatic and terrestrial vertebrates differ in this way?. Choices: - bisexually - unisexually - asexually - sexually A:
sexually

Q: What are the two metals within a battery called? Read this paragraph and choose the correct option from the provided answers: These values suggest that water should be oxidized at the anode because a smaller potential would be neededusing reaction (ii) for the oxidation would give a less-negative cell potential. When the experiment is run, it turns out chlorine, not oxygen, is produced at the anode. The unexpected process is so common in electrochemistry that it has been given the name overpotential. The overpotential is the difference between the theoretical cell voltage and the actual voltage that is necessary to cause electrolysis. It turns out that the overpotential for oxygen is rather high and effectively makes the reduction potential more positive. As a result, under normal conditions, chlorine gas is what actually forms at the anode. Now consider the cathode. Three reductions could occur:. Choices: - sheath and a cathode - anode and sheath - anode and diode - anode and a cathode A:
anode and a cathode

Q: Which other planet in the solar system is the easiest to observe from earth? Read this paragraph and choose the correct option from the provided answers: Mars is the easiest planet to observe. As a result, it has been studied more than any other planet besides Earth. People can stand on Earth and observe the planet through a telescope. We have also sent many space probes to Mars. In April 2011, there were three scientific satellites in orbit around Mars. The rover, Opportunity, was still moving around on the surface. No humans have ever set foot on Mars. NASA and the European Space Agency have plans to send people to Mars. The goal is to do it sometime between 2030 and 2040. The expense and danger of these missions are phenomenal. Choices: - Pluto - Mercury - Jupiter - mars A:
mars

Q: What type of energy travels through space as electrical and magnetic waves? Read this paragraph and choose the correct option from the provided answers: 4. Electromagnetic energy is energy that travels through space as electrical and magnetic waves. The light flooding the stage in the Figure above is one type of electromagnetic energy. Other types include radio waves, microwaves, X rays, and gamma rays. Choices: - sound energy - mechanical energy - solar energy - electromagnetic energy A:
