某县级市为发展当地经济,拟出让县政府所在镇中心区的一块规划建设用地的土地使用权,该市规划行政主管部门依据镇中心区的控制性详细规划提出了规划条件,如图2-6-1所示。

甲房地产开发公司通过土地市场公开交易的方式,取得了该用地的土地使用权,并与土地行政主管部门签订了土地使用权出让合同。出让合同中明确了出让地块的位置、使用性质、容积率、绿地率和需要同步建设的公共服务设施等要求,但未对建筑高度作出明确规定。

甲公司在组织编制修建性详细规划时,为了突出企业形象和便于建筑布局,向规划行政主管部门提出了以下要求。

1.将用地内原规划安排在西北角的消防站调整到用地东北角。

2.在维持其他规划条件不变的前提下,将用地东南角三栋住宅楼的建筑高度由18m增加到30m。

该市规划行政主管部门委托省规划院进行专题论证,认为甲公司提出的要求不违背镇总体规划,也有利于城市景观和城市功能布局优化。

试问:1.甲公司在通过公开交易的方式取得土地使用权后,是否还可以向市规划行政主管部门提出变更规划条件的申请为什么

2.该市规划行政主管部门是否可以依法批准甲公司的以上申请为什么依法批准必须履行的程序是什么

在一个海岛中,一种海龟中有的脚趾是连趾(ww),有的脚趾是分趾(Ww、WW),连趾便于划水,游泳能力强,分趾游泳能力较弱。若开始时,w和W的基因频率各为0.5,当岛上食物不足时,连趾的海龟更容易从海中得到食物。若干万年后,基因频率变化为W为0.2,w为0.8。
