Answer the following question given this paragraph: Following fertilization, the sporophyte forms. The sporophyte is connected to, and dependent on, the gametophyte. Q: What is connected to, and dependent on, the gametophyte? Choices: - the sperm - the chromosomes - the zygote - the sporophyte A:
the sporophyte

Answer the following question given this paragraph: In the absence of a net force, objects move in a straight line. If they turn that is, if their velocity changes, even only in direction there must be an applied force. Forces which cause objects to turn around continuously in a circle are known as centripetal forces. When an object moves in a circle its velocity at any particular instant points in a direction tangent to the circle. The acceleration points towards the center of the circle, and so does the force acting on it. This is only natural, when you think about it if you feel a force pushing you towards your left as you walk forward, you will walk in a circle, always turning left. Q: Forces which cause objects to turn around continuously in a circle are known as? Choices: - frictional forces - tension forces - hydrodynamic forces - centripetal forces A:
centripetal forces

Answer the following question given this paragraph: Athletics are very competitive these days at all levels, from school sports to the pros. Everybody is looking for that edge that will make them faster, stronger, more physically fit. One approach taken by many athletes is the use of amino acid supplements. The theory is that the increase in amino acids in the diet will lead to increased protein for muscles. However, the only real benefit comes to the people who make and sell the pills. Studies have not showed any advantage obtained by the athletes themselves. You're much better off just maintaining a healthy diet. Q: Which is the best way to maintain a strong, fit body? Choices: - bodybuilding - regular exercising - being a vegetarian - a healthy diet A:
a healthy diet

Answer the following question given this paragraph: The space shuttleand any other rocket-based systemuses chemical reactions to propel itself into space and maneuver itself when it gets into orbit. The rockets that lift the orbiter are of two different types. The three main engines are powered by reacting liquid hydrogen with liquid oxygen to generate water. Then there are the two solid rocket boosters, which use a solid fuel mixture that contains mainly ammonium perchlorate and powdered aluminum. The chemical reaction between these substances produces aluminum oxide, water, nitrogen gas, and hydrogen chloride. Although the solid rocket boosters each have a significantly lower mass than the liquid oxygen and liquid hydrogen tanks, they provide over 80% of the lift needed to put the shuttle into orbitall because of chemical reactions. Q: What do rocket-based systems use to propel itself into space? Choices: - water reactions - hydrogen reactions - nuclear reactions - chemical reactions A:
chemical reactions
