gymnosperms and angiosperms

Answer the following question given this paragraph: As we saw in the previous chapter, ions are formed when atoms gain or lose electrons. If an atom loses one or more electrons, the resulting ion has a positive charge (more protons are present than electrons). If the atom gains one or more electrons, the resulting ion has a negative charge (more electrons are present than protons). Positive ions are called cations, and negative ions are called anions. Because opposite charges attract one another, cations and anions are held together by strong electromagnetic forces. An ionic compound consists of a large three-dimensional array of alternating cations and anions. For example, sodium chloride (NaCl) is composed of Na + and Cl - ions arranged into a structure like the one shown in Figure below . Q: When atoms gain or lose electrons, what is formed? A:
OPTIONS:
- crystals
- molecules
- gas
- ions

Answer: ions

Question: Answer the following question given this paragraph: Alkenes are unsaturated hydrocarbons with at least one double bond between carbon atoms. Q: What are unsaturated hydrocarbons with at least one double bond between carbon atoms called? A:
OPTIONS:
- amines
- enzymes
- peptides
- alkenes

input with options: Answer the following question given this paragraph: The core is the Sun's innermost layer. The core is plasma. It has a temperature of around 15 million degrees Celsius (C). Nuclear fusion reactions create the immense temperature. In these reactions, hydrogen atoms fuse to form helium. This releases vast amounts of energy. The energy moves toward the outer layers of the Sun. Energy from the Sun's core powers most of the solar system. Q: The innermost layer of the sun is known as what? A:
OPTIONS:
- photosphere
- surface
- convective zone
- core
output: core

Problem: OPTIONS:

Q: Answer the following question given this paragraph: Q: What ensures that seeds germinate only when conditions for seedling survival are optimal? A:
Answer:
seed dormancy
