Pure cheese pizza soul, authentic pizza usually use rich in protein, vitamins, minerals and calcium in very low calorie mozzarella cheese ( Mozzarella ).

由题意可知，B、C为气态，固态B常用作致冷剂，可用于人工降雨，固态B是干冰，由此可以判断B为二氧化碳（CO ₂ ）；
又知A是烤制糕点所用的发酵粉的主要成分之一，医疗上又是治疗胃酸过多的一种药剂，由此判断A是小苏打（NaHCO ₃ ）；
又知D是生活中重要的调味品，是人们正常生理活动所必不可少的物质，由此判断D是食盐（NaCl）；
又知A与C的水溶液反应生成水、B和D，化学方程式应该为NaHCO ₃ +HCl=NaCl+H ₂ O+CO ₂ ↑，故C为HCl．
故答案为；CO ₂ ；HCl；NaCl．

解题思路：此题主要考查的是微生物与人类生活的关系以及发酵技术在食品、药品等制作中的应用，据此解答．

细菌、真菌等微生物在食品的制作中具有重要的作用，制面包要用到酵母菌，酵母菌可以分解面粉中的葡萄糖，产生二氧化碳，二氧化碳是气体，遇热膨胀而形成小孔，使得馒头或面包暄软多空；酸奶是以鲜牛奶为原料，加入乳酸菌发酵而成，牛奶经酵母菌的发酵后使原有的乳糖变为乳酸，易于消化，所以具有甜酸风味，其营养成份与鲜奶大致相同，是一种高营养食品；青霉、放线菌等可以产生抗生素，如青霉素、庆大霉素等，这些药物能治疗细菌性疾病，在人类与疾病的斗争中发挥了重要作用．
故答案为：酵母菌；乳酸菌；抗生素

点评：
本题考点： 发酵技术在食品制作中的作用．

考点点评： 掌握常见的微生物与食品制作的例子，并理解其制作原理．

D

既有物理变化（如颜色,形状,密度等发生改变）又有化学变化（由竹子变成炭）.
木炭的结构疏松多孔,吸附性很好,可以吸附色素,有毒气体,臭味等

261*840/360=609

（1）由表中提供的数据可知，当烤制的风味肠的质量为2.5千克时，需要烤制时间是24分钟；
（2）从表中可以看出，风味肠的质量每增加0.5千克，烤制风味肠的时间增加4分钟，由此可知烤制时间是风味肠的质量的一次函数，设烤制时间为y分钟，风味肠的质量为x千克，y与x的一次函数关系式为：y=kx+b，
由题意可得：12=k+b，20=2k+b，
解得k=8，b=4，
所以y=8x+4，
当x=a千克时，y=8a+4，
所以当烤制的风味肠的质量为a千克时，需要烤制风味肠的时间是（8a+4）分钟。
