Answer the following question given this paragraph: Q: If a sperm fertilizes an egg of a seed plant, the zygote grows into what? Choices: - homostatic embyro - pulsation embryo - progeny embryo - sporophyte embryo A:
sporophyte embryo
Answer the following question given this paragraph: All crocodilians have, like humans, teeth set in bony sockets. But unlike mammals, they replace their teeth throughout life. Crocodiles and gharials (large crocodilians with longer jaws) have salivary glands on their tongue, which are used to remove salt from their bodies. This helps with life in a saltwater environment. Crocodilians are often seen lying with their mouths open, a behavior called gaping . One of its functions is probably to cool them down. Q: Lying with their mouths open, a behavior called gaping, probably serves what function for crocodiles? Choices: - sleeping - digesting - eating - cooling down A:
cooling down
Q: Answer the following question given this paragraph: The motion of individual molecules in a gas is random in magnitude and direction. However, a gas of many molecules has a predictable distribution of molecular speeds, known as the Maxwell-Boltzmann distribution. Q: What do we call the predictable distribution of molecular speeds found in gas of many molecules? Choices: - mitchell - boltzmann distribution - burns - boltzmann distribution - kemp - boltzmann distribution - maxwell-boltzmann distribution A:
A: maxwell-boltzmann distribution
Question: Answer the following question given this paragraph: A dipole occurs when two opposite charges are separated by some amount of distance. We have already seen dipoles in the form of polar bonds. For example, each O-H bond in water is an example of a dipole; the partial positive charge on hydrogen is separated from the partial negative charge on oxygen by the length of the bond. A molecular dipole is the geometric sum of all the individual bond dipoles in a molecule. In order for a molecule to have a dipole, it must have at least one polar bond. However, not all molecules with polar bonds have an overall molecular dipole. Sometimes the dipoles within a molecule will effectively cancel each other out, giving a zero net molecular dipole. This is often seen in symmetrical molecules. Q: What occurs when two opposite charges are separated by some amount of distance? Choices: - particle - radioactivity - diffusion - dipole A:
Answer: dipole

Answer the following question given this paragraph: Analogous structures are structures that are similar in unrelated organisms. The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor. For example, the wings of bats and birds, shown in Figure below , look similar on the outside. They also have the same function. However, wings evolved independently in the two groups of animals. This is apparent when you compare the pattern of bones inside the wings. Q: What term is used to describe structures that are similar in unrelated organisms? Choices: - reproductive - symbolic - isolated - analogous A:
**Answer**
analogous

Answer the following question given this paragraph: Discussion Quite a trip (if it survives)! Note that this distance is the total distance traveled by the fly. Displacement is actually zero for complete revolutions because they bring the fly back to its original position. The distinction between total distance traveled and displacement was first noted in One-Dimensional Kinematics. Q: Where was the distinction between total distance traveled and displacement first noted? Choices: - uncertainty principle - Newton's first law - string theory - one-dimensional kinematics A:
**Answer**
one-dimensional kinematics
