Answer the following question given this paragraph: Watch this video (http://openstaxcollege. org/l/pollen_release) to see a cedar releasing its pollen in the wind. Female Gametophyte The female cone also has a central axis on which bracts known as megasporophylls (Figure 32.10) are present. In the female cone, megaspore mother cells are present in the megasporangium. The megaspore mother cell divides by meiosis to produce four haploid megaspores. One of the megaspores divides to form the multicellular female gametophyte, while the others divide to form the rest of the structure. The female gametophyte is contained within a structure called the archegonium. Q: What does the megaspore mother cell produce after meiosis division? Choices: - four diploid megaspores - two diploid megapores - two haploid megaspores - four haploid megaspores A:
four haploid megaspores

Ques: Answer the following question given this paragraph: Many covalent compounds, especially those containing carbon and hydrogen, burn easily. In contrast, many ionic compounds do not burn. Q: Which types of compounds are more likely to burn easily? Choices: - hydroxyl - salty - chlorophyll - covalent A:
Ans: covalent
(Q).
Answer the following question given this paragraph: Salt isn't the only solute that dissolves in water. In fact, so many things dissolve in water that water is sometimes called the universal solvent. Water is such a good solvent because it is a very polar compound. A polar compound has positively and negatively charged ends. Solutes that are also charged are attracted to the oppositely charged ends of water molecules. This allows the water molecules to pull the solute particles apart. Q: Which compound has positively and negatively charged ends? Choices: - tumultuous compound - non-polar compound - real compound - polar compound A:
(A).
polar compound

Choices: - plains erosion - fertilizer erosion - vegetable erosion - soil erosion A:

Ans:soil erosion
