Answer the following question given this paragraph: Founder effect occurs when a few individuals start, or found, a new population. By chance, allele frequencies of the founders may be different from allele frequencies of the population they left. An example is described in the Figure below . Q: What effect occurs when a few individuals start, or found, a new population? Choices: - divergent - convergent - pioneer - founder A:
founder
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
Q: Answer the following question given this paragraph: The asthenosphere is below the lithosphere. The asthenosphere is also in the upper mantle. This layer is solid, but it can flow and bend. A solid that can flow is like silly putty. Q: Which layer is found below the lithosphere? Choices: - troposphere - magnetosphere - stratosphere - asthenosphere A:
A: asthenosphere
Question: Answer the following question given this paragraph: Coefficients are used to balance chemical equations. A coefficient is a number placed in front of a chemical symbol or formula. It shows how many atoms or molecules of the substance are involved in the reaction. Q: What is the number placed in front of a chemical symbol or formula that shows how many atoms or molecules of the substance are involved in the reaction? Choices: - requirement - frequency - note - coefficient A:
Answer: coefficient

Answer the following question given this paragraph: In many species display behaviors, rather than actual physical attacks, are used to show aggression. This helps prevent injury and death. Male gorillas, for example, are more likely to put on a display of aggression than to attack another male. In fact, gorillas have a whole series of display behaviors that they use to show aggression. They beat on their chest, dash back and forth, and pound the ground with their hands. Q: How do the male gorillas show display behaviors? Choices: - food gathering - vocalization - spontaneous mutation - showing aggression A:
**Answer**
showing aggression
Answer the following question given this paragraph: Magnetism is due to the movement of electrons within atoms of matter. When electrons spin around the nucleus of an atom, it causes the atom to become a tiny magnet, with north and south poles and a magnetic field. In most materials, the electrons orbiting the nuclei of the atoms are arranged in such a way that the materials have no magnetic properties. Also, in most types of matter, the north and south poles of atoms point in all different directions, so overall the matter is not magnetic. Examples of nonmagnetic materials include wood, glass, plastic, paper, copper, and aluminum. These materials are not attracted to magnets and cannot become magnets. Q: Magnetism is due to the movement of what within atoms? Choices: - neutrons - protons - magnetrons - electrons A:
electrons
