请教申请费中孩子部分的生物信息采集费用，根据instruction，如下
The filing fee for Form I-751 is $595. A biometric services fee of $85 is also required for petitioners.
Each conditional resident dependent, eligible for inclusion on the principal petitioner’s Form I-751 and listed under Part5. of Form I-751, is required to submit an additional biometric services fee of $85, including dependents residing overseas pursuant to military or Government orders, regardless of age.
是不是只要是在第五部分有孩子的，也即是不管孩子是否要申请去掉条件，都需要加一个生物信息费85？
是不是只需要一帐支票，把所有的费用在一张支票上？
