Jared, age 54, earns $300,000 per year and is a participant in his employer’s 401(k) plan. Ignoring the ADP Test requirements, what is the maximum amount that Jared can defer under the 401(k) plan in 2025?  

5. Differentiation in the first 10s of million years of the Solar System (10pts Total]: 1) (5pts) Provide an explanation/example of what is meant by the statement “Our solar system is heterogeneous in composition.” Read 1) and 2) to avoid redundancy in answering. 2) (5pts) How is a protostar similar and yet different from a main-sequence star. 3) (5pts) Compare how planetary accretion of nebular material by planets was different the accretion disk prior to development of the protostar vs after the development of the protostar. Before   After  

9. Archaean Sphere Interactions (10pts Total): The graph below shows the composition of Earth’s atmosphere through time may be useful in answering this question. A) (7pts) CO2 (carbon dioxide) content of Earth’s atmosphere decreased rapidly from 35% at 3.3 Ga to less than 5% by 2.0 Ga. Explain the multi-step process by which CO2 was removed from the atmosphere. Please include verbal descriptions of different carbon/oxygen species in the series of chemical reactions that answer this question from start to end.   B) (3pts) Globally iron ore deposits are typically Late Achaean to Early Proterozoic in age. What was the source of the Fe at the Earths surface, and describe the process by which iron increased its from a few % to greater than 40% making it an economical ore deposit beginning around ~2.2 Ga (the graph may be of some assistance).

2. Silicate Mineral Structure (10pts Total, in two parts): (Part 1 of 3) 2A  Which of the following (1, 2,  or 3) best represents the unit cell of the mineral structure structure shown below.

2. Silicate Mineral Structure (10pts Total, in two parts): (Part 2 of 3) Some rock forming silicate minerals have the Silica tetrahedra polymerized into triple chains as shown below. The blue box shows the smallest repeating unit cell of the triple chain structure. 2B) (8pts): Determine the Si:O ratio for a triple chain silicate fill in the blanks below.   Si : O (numbers only and no simplification). See Following question 2B for follow up on this question.
