It is highlighted that besides passive transport , dissolved metal transport into bivalves was involved in active transport coupled with atp 强调了贝类对溶解态重金属的转运除了被动转运之外，还涉及到需要atp供能的主动转运过程。
The public is reminded to : clean and cook seafood thoroughly before eating , particularly crustaceans and bivalves such as shrimp , crab , oysters and clams 海产要彻底洗净和煮熟方可进食，尤其是贝壳及双壳贝类海产如虾蟹蚝及蚬等
In the fairly deep lake facies there found abundant bivalve fossils , such as the standard foss il of permian in north xingjiang - tarfaniasp . , 半深湖相中发现丰富的瓣鳃类动物化石，如北疆地区二叠系标准化石?吐鲁番鳕鱼及介形类等。
Bivalves include all dorsoventrally compressed mollusc species ; they typically have two - part shells dorsally hinged by strong muscles and ligaments 双壳贝包含所有背腹扁平的软体动物,其特徵包括：具有双壳,在背部有强韧的肌肉和韧带连接双壳
Although the bivalve lineages dr jablonski studied spread out from the equator in waves , they did not become extinct in the wake of these waves 尽管捷布朗斯基博士所研究的双壳类世系随着波涛从赤道开始蔓延扩散，但它们并没有随着波涛的消亡而一同绝灭。
Members of the trade are reminded to : clean and cook food thoroughly before consumption , particularly crustacean and bivalve seafood such as shrimp , crab , oysters and clams 食物包括海产要彻底洗净和煮熟方可进食，尤其是甲壳及双壳类海产如虾蟹蚝及蚬等
The uptake of dissolved metals , a potentially significant source for overall metal accumulation in bivalves , is liable to be influenced by biotic and abiotic factors 摘要对溶解态重金属的吸收是贝类累积重金属的重要来源之一，易受到生物因素和非生物因素的影响。
Bivalve shellfish such as scallops , clams , mussels , oysters , fan shells are commonly involved since they are filter - feeders and ingest toxic algae in water 带子、蚬、青口、蚝、扇贝等双壳贝类，通常是造成贝类中毒的媒介。这是因为它们是滤食性生物，容易摄取水中的毒藻。
The aims of this part of the test are to determine the habitat of the marine bivalve samples and to identify the exomorphological and anatomophysiological characteristics associated to these habitats 此部分的目的,是要判断不同样本在海中生存的环境为何?并指出外部形态及生理解剖特徵,与它们栖息环境的关系
Cd content of bivalves had exceeded healthy standards for human consumption , and the contents of cu and zn in oyster had also slightly exceeded healthy standards for human consumption 但贝类的cd含量已超过“人体卫生消费标准” ，其中牡蛎的cu和zn含量则略超过“人体卫生消费标准” ，其食用价值受到严重威胁，应引起重视。
