Answer the following question given this paragraph: Gas exchange is needed to provide cells with the oxygen they need for cellular respiration. Cells cannot survive for long without oxygen. Gas exchange is also needed to carry away carbon dioxide waste. Some of the carbon dioxide in the blood dissolves to form carbonic acid, which keeps blood pH within a normal range. Q: What is needed to provide cells with the oxygen they need for cellular respiration? Choices: - vascular tissue - passive transport - photosynthesis - gas exchange A:
gas exchange
Answer the following question given this paragraph: Q: Animals can transport what waste material in the circulatory system and store it safely at high concentrations? Choices: - proteins - carbon - phosphorus - urea A:
urea
Q: Answer the following question given this paragraph: Converging plates can be oceanic, continental, or one of each. If at least one is oceanic, it will subduct. A subducting plate creates volcanoes. Many of the world's volcanoes are the result of subduction at a convergent plate boundary. A map of the world's active volcanoes is pictured below ( Figure below ). Q: Converging plates can be oceanic, continental, or one of each. if at least one is oceanic, it will subduct. a subducting plate creates what? Choices: - earthquakes - fires - wind - volcanoes A:
A: volcanoes
Question: Answer the following question given this paragraph: Sperm are male gametes , or reproductive cells. When a male gamete meets a female gamete, they can form a new organism. Sperm form when certain cells in the male reproductive system divide by meiosis , resulting in cells with half the amount of DNA as a regular "body" cell. More precisely, sperm cells are haploid sex cells, having one set of chromosomes. Regular body cells are diploid, having two set of chromosomes. As there are 46 chromosomes in a diploid human cell, how many are in a human sperm cell?. Q: How many chromosomes are in a diploid human cell? Choices: - 46.63 chromosomes - 41 - 47 - 46 chromosomes A:
Answer: 46 chromosomes
