New findings suggest that brainy card games such as contract bridge may temporarily(临时地) raise production of a key blood cell including in fighting off illness. After 90 minutes of play, bridge players had increased levels of immune(免疫) cells, according to the research reported last week.

A researcher, Diamond, studied bridge players from a women’s bridge club. She chose bridge players because the game includes skills stimulating(刺激) a part of the brain called the dorsolateral cortex. Earlier animal research suggests that this part of the brain may play a role in the immune system.

The findings are based on blood samples drawn from 12 women players. Their blood samples showed a rise in levels of white blood cells called T cells after they played bridge for 90 minutes. T cells are produced by the thymus gland(胸腺) and used by the immune system against diseases.

The T cell count jumped significantly in eight of the bridge players, and slightly in the other four. The findings contribute to the field of neuroimmunology(神经免疫学), whose name reflects the fact that the nervous system and the immune system are not considered separate and isolated(独立的) systems. What isn’t clear is whether the help to the immune system from an activity like contract bridge is lasting or temporary. It is also not clear whether the increase in T cells could finally be targeted against special illnesses.

某建设单位准备建一座图书馆，建筑面积5000m²，预算投资400万元，建设工期为10个月。工程采用公开招标的方式确定承包商。按照《中华人民共和国招标投标法》和《中华人民共和国建筑法》的规定，建设单位编制了招标文件，并向当地的建设行政管理部门提出了招标申请书，得到了批准。

建设单位依照有关招标投标程序进行公开招标。

由于该工程在设计上比较复杂，根据当地建设局的建议，对参加投标单位的主体要求是最低不得低于二级资质。

拟参加此次投标的5家单位中A、B、D为二级资质，C单位为三级资质，E单位为一级资质，而C单位的法定代表人是建设单位某主要领导的亲戚，建设单位招标工作领导小组在资格预审时出现了分歧，正在犹豫不决时，C单位提出准备组成联合体投标，经C单位的法定代表人的私下活动，建设单位同意让C与A联合承包工程，并明确向A暗示，如果不接受这个投标方案，则该工程的中标将授予B单位。A为了获得该项工程，同意了与C联合承包该工程，并同意将停车楼交给C单位施工。于是A和C联合投标获得成功。A与建设单位签订了《建设工程施工合同》，A与C也签订了联合承包工程的协议。

问题：

通常情况下，招标人和投标人串通投标的行为有哪些表现形式？
