<span>As humans change the way we live on the planet, the way that nitrogen moves around the Earth also changes. Nitrogen atoms may seem small enough to be easily overlooked. We look right through the ones in the air, do we not? Yet recent changes in the nitrogen cycle are causing a very noticeable effect on natural environments and human health. Lakes are clogged with aquatic weeds. Dead zones have formed in areas of the oceans where animals can not survive. Air pollutants that contain nitrogen are decreasing air quality and greenhouse gases that contain nitrogen are becoming more common.</span>

Answer:
c) pure water on the produce would put it in a hypotonic environment and keep the produce firm.
Explanation:
Ideally, in a natural environment, plants leafs remain fresh and firm looking by absorbing water from their natural environment. However, in a case where these vegetables have been removed from their natural environment, they have lost the ability to absorb water under natural conditions.
In order to keep the leaf cells of the vegetables firm and rigid, so they can look fresh and appealing, they have to be placed in a hypotonic condition i.e. an external condition with high concentration of water. To do this, a grocer in a supermarket will occasionally spray the vegetables with pure water to keep the vegetables' cell from drying out and hence lead to wilting, which would make the vegetables less appealing to customers.
Access Control Points
They are restrictions points that enforce regulations and guidelines on decontamination when exiting the sites and ensuring adherence safety standards when entering the site. The regulation are usually, as standard practice, conspicuously posted at the Access Control Points.
Access Control Points are usually set up at the periphery of the Exclusion Zones, and ideally, there should be a separate entrance and exit Control Access Point.
