小白求教爱思唯尔期刊投稿关于【利益声明】里的一个问题

第一次投爱思唯尔。请教下  Guide for author里关于利益声明有下面这段话。期刊simulation modelling practice and theory。这个期刊是单盲审。
小白求教几个问题：
1.这段话就是说要在manuscript里写上利益声明，然后要另外提交单独的利益声明吗？
2.利益声明写在manuscript的什么位置呢？acknowledge里吗？
3.如果有国家自然科学基金这种赞助，是不是写上赞助基金就是利益声明了，就不用写 'Declarations of interest:
none'.了？

Declaration of interest
All authors must disclose any financial and personal relationships with other people or organizations
that could inappropriately influence (bias) their work. Examples of potential conflicts of interest include:
employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/
registrations, and grants or other funding. Authors must disclose any interests in two places: 1. A
summary declaration of interest statement in the title page file (if double-blind) or the manuscript file
(if single-blind). If there are no interests to declare then please state this: 'Declarations of interest:
none'. This summary statement will be ultimately published if the article is accepted. 2. Detailed
disclosures as part of a separate Declaration of Interest form, which forms part of the journal's official
records. It is important for potential interests to be declared in both places and that the information
matches.
