Mitosis results in two cells with the same number of chromosomes as the parent cell. How do eukaryotic cells differ from prokaryotic cells? How do animal cells differ from plant cells? - CORRECT ANSWER >>> Eukaryotic cells contain membrane bound organelles, including a nucleus containing their genetic material. Prokaryotic cells lack membrane bound organelles and their genetic material floats in the cytoplasm. Animal cells lack a cell wall and chloroplasts; plant cells do not have centrioles or lysosomes.

D Solution B is 1000 times more acidic than solution A. - CORRECT ANSWER >>> A An ice boat glides along the surface of a frozen lake, powered by the wind in its sails. If a 75 kg sailboat experiences an initial acceleration of 6 m/s2 under a moderate wind, what would be the expected acceleration of a 225 kg sailboat with an identical sail, assuming the same net force was delivered? a 2 m/s b 3 m/s c 6 m/s d 18 m/s2 - CORRECT ANSWER >>> A Which layer of the Earth comprises the greatest percent of the planet's volume? a inner core b outer core

Each dart is about 20 g. What is the average magnitude of force applied by the expanding spring? A 3 N B 7.5 N C 3000 N D 7500 N - CORRECT ANSWER >>> A F = ma Blood flows from what part of the heart to the lungs? A right ventricle B left atrium C left ventricle D right atrium - CORRECT ANSWER >>> A pathway is right atrium - > right ventricle - > lungs - > left atrium - > left ventricle - > body In a chemistry lab, you are given four solutions (A-D). You measure their pH values and record them in the table below:
Which solution contains the greatest number of hydrogen ions? A = 2. B = 3. C = 7. D = 9.0 - CORRECT ANSWER >>> A pH is a measure of how basic or acidic a solution is. Acids have a pH below 7, and they release hydrogen ions when in solution. The more acidic a solution, the lower the pH, and the greater the number of hydrogen ions it releases in solution. Thus, the solution with the smallest pH will be the most acidic, and contain the greater number of hydrogen ions. Which of the following traits is NOT determined by inheritance alone? A eye color B intelligence C hair color D eye shape - CORRECT ANSWER >>> B As part of the water cycle, water enters the atmosphere as a gas through A transpiration B condensation C precipitation
The temperature of water in an open beaker is raised from 25° C to 50° C. Which of the following is NOT true of this change? A The molecules of water have an increased amount of energy. B The molecules of water are moving past each other more rapidly. C The water molecules break apart, forming oxygen and hydrogen gas. D Some of the liquid water escapes as water vapor. - CORRECT ANSWER >>> C You are an engineer building a spaceship. In your spaceship model, the length of the fuel tank is 25 cm. You must scale this up by 100 times when constructing the actual spacecraft. On the actual spacecraft, what is the length of the fuel tank? A 25 m B 1000 cm C 25 km D 2500 mm - CORRECT ANSWER >>> A The overall charge on a non-ionized atom is A positive B zero C negative D variable - CORRECT ANSWER >>> B
Think about what it means for an atom to be non-ionized: a non-ionized atom has the same number of protons as electrons. Since the positive and negative charges cancel out, the overall charge is zero, making any non-ionized atom electrically neutral.
- The rings of Saturn are comprised primarily of A clusters of small moons B gasses C asteroids D ice crystals - CORRECT ANSWER >>> D Which of the following rocks is the result of a chemical process? A quartzite B granite C sandstone D coal - CORRECT ANSWER >>> A "Waves" of heat can be seen above a hot stove element or flame, as the background appears to be distorted or out of focus just at that spot. This is an example of A diffraction B refraction C reflection D convergence - CORRECT ANSWER >>> B
