Employers that set up money purchase plans must declare a set contribution level each year in the plan document, based on employeesâ salaries. Companies can contribute up to 25% of the total annual compensation of all plan participants, up to 100% of each participantâs salary or $54,000 (in 2017, up from $53,000 in 2016), whichever is less.
There are important distinctions between seagrasses and seaweed. Seagrass can easily be confused with marine macroalgae, or seaweed, but there are many important differences between the two. While seagrasses are considered vascular plants and have roots, stems and leaves, seaweed are multi-cellular algae and have little or no vascular tissues.
The difference between a sea and a lake largely comes down to permanence. A sea is a more permanent feature, while a lake is relatively temporary. This time frame is relative, and should be examined on a scale of millions of years. On a geological scale that includes and measures other massive, slow events such as ice ages and plate shifts, a lake is a temporary feature.
