Answer the following question given this paragraph: distinctly differ from the adult form, spending 3 to 15 years as suspension feeders. Once they attain sexual maturity, the adults reproduce and die within days. Lampreys possess a notochord as adults; however, this notochord is surrounded by a cartilaginous structure called an arcualia, which may resemble an evolutionarily early form of the vertebral column. Q: What do we call the cartilaginous structure that surrounds the notochrod? Choices: - osteocytes - clavicle - membrane - arcualia A:
(Answer)
arcualia

Ques:Answer the following question given this paragraph: The strength of a base depends on how many hydroxide ions it produces when it dissolves in water. A stronger base produces more hydroxide ions than a weaker base. For example, sodium hydroxide (NaOH), a base in drain cleaner, is a strong base because all of it breaks down into ions when it dissolves in water. Calcium carbonate (CaCO 3 ), a base in antacids, is a weak base because only a small percentage of it breaks down into ions in water. Q: What determines the strength of a base when dissolved in water? Choices: - amount of phosphorus ions produced - pH level - saline content - amount of hydroxide ions produced A:

Ans:
amount of hydroxide ions produced
