是的
一、小肠很长,它具有小肠绒毛壁、毛细血管壁和毛细淋巴管壁,大大增加了小肠内表面的面积,扩大了约600倍.
二、小肠绒毛壁、毛细血管壁和毛细淋巴管壁都很薄,都有一层上皮细胞构成,有利于营养物质的吸收.

带叶子的蔬菜都不能隔夜吃!最容易变质,产生对人体有害的物质.

I have a childhood friend who has been a close buddy of mine since we were just toddlers. Her name is XXX, she's a sixteen year old girl, the same age as me, and we both study at Guangyang Secondary School (这校名我乱编的,你可以自己写一个). Perhaps it was a stroke of luck or maybe it was fated, we are both in the same class and have shared many common memories in our beloved Class A2 (班级也乱编的). She has many things she love and one of those would definitely be japanese sushi! She has a unique taste that happens to be quite difficult to satisfy, therefore she's a very picky eater. Being an active and outgoing person, XXX is involved in many activites. They include sports such as swimming and tennis, to crafts, dance and even being a member of the photographic society - need I mention that her photography skills are top-notch! She loves everything thing that she do and has always been a great motivation to me. I'm really glad to have her as a friend and I hope that this friendship will be one to last a lifetime.

放冰箱里、 用盐腌、 真空密封等等；但最好的办法就是在食物的保质期内把她吃掉.
食物发霉主要是氧化反应,只要隔绝了空气就不会发霉.(保鲜膜 真空包装)
或者是将其放置到低温环境中,使导致食物发霉的霉菌不能生长.
或者使食物失去水分,可以用风干 盐腌的方法.
不要一次买太多,用完再买.4放些可食用的干燥剂

最佳答案 1、低温保存.在低温环境下,食物中的微生物生长减慢,代谢也减缓,因而变质也会减慢.
2、干燥保藏.干燥降低食物中的水分,当食物中水分降低到一定程度后也会大大减慢食物变质的速度.
3、灭菌密封保藏.
4、高盐、高糖腌渍,如咸菜、果脯等.
5、真空包装也可以一定程度减缓食物变质.
6、加入适量的食品防腐剂等等

每天不超过一千大卡,指的是你吃的东西的热量不超过一千大卡,
拿米饭来说吧,一般饭店的小碗的米饭,一碗是220大卡,如果你吃五碗就有1100大卡了,
具体的你去查下网上的卡路里表格,一般一个苹果是55大卡,其他类似于苹果体积的一个水果也是50大卡左右,
建议你每天早上吃一小碗粥(50大卡),配合一标准分的豆腐脑(50-100大卡),再加点小菜,别吃太油的,这样早上控制在200大卡左右,又容易消化,千万别吃油条,热量太大,还不消化
中午的热量控制在400-500大卡,你可以吃一小碗饭(220大卡),配合适量的蔬菜,别太油的那种,然后吃肉的话,最好是鱼肉或者是瘦肉,鱼肉100克是170大卡,瘦肉一百克是130大卡左右,一个人每天需要吃肉的量是一两
晚上喝点粥加点水果,水果别多吃,两到三个最多,这样就把你的万餐摄入热量控制在200卡内.
总共算下来你一天吃入的事物热量在900大卡,白天饿的时候可以吃100大卡的零食,建议吃梅子,或者无糖可乐(这个对身体不好,最好别喝,如果实在谗可以喝点增添饱腹感),还可以吃苹果,苹果内的果胶遇水会在胃里膨胀,会不太饿了
以上都是我按你要求结合卡路里表设计的,如果你觉得不适合可以,自己去查卡路里表,毕竟个人口味不同,控制在一千大卡内不是很难的事情,油少,糖少,控制食量就可以了

点燃,能烧,发热,发光.其中的化学能转化为内能和光能

应该可以.食盐由于本身盐度比动植物细胞液内浓度高,所以会使细胞液失水皱缩,从而使微生物因失水而死亡,从而起到防腐作用.
