Every deliberate act of wrongdoing by the master or any of the crew against the ship or cargo，without the authorization or privity of the Shipowner or his agent，is（）.

（）, or drum is used for hauling in or letting out the wires or ropes which will fasten the ship to the shore.

A salvor may be（）the whole or part of the payment due under Salvage Convention to the extent that the salvage operations have become necessary or more difficult because of fault or neglect on his part or if the salvor has been guilty of fraud or other dishonest conduct.

The （） is used for hauling in or letting out the wires or ropes.

Vessels must be（）valid certificate of nationality or certificated of registry or license.

When loading or discharging dry mud or cement，crew members should use goggles and（）.

逻辑运算符（AND、NOT、OR）的运算顺序是AND→OR→NOT。

下面对基因突变、基因重组和染色体变异的比较中，叙述不正确的是（）。

《普通高中生物课程标准（实验）》关于一节实验探究课“自由组合规律试验”的具体要求是：会解释自由组合现象，推断自由组合规律的结果，理解其实质。基因自由组合规律是继基因分离规律的第二大遗传学规律，其在内容上着重阐明了基因自由组合规律的机制和实质：在方法上侧重于假说-演绎科学方法的应用。本节课通过孟德尔两对相对性状的杂交试验具体事例，领悟假说-演绎科学方法；根据实验现象，按照“发现问题-提出假说-验证假说-得出结论”的思路，尝试进行杂交、测交等遗传实验的设计，进而归纳出基因自由组合规律。依据上述材料，确定本节课的教学方法。
