Answer:

16 pg at the end of S

16 pg at the end of G2

Explanation:

A cell has 8 pg of DNA per nucleus in G1.

During S phase the DNA replicates, so every nucleus will contain double the normal amount of DNA that was present in G1. Therefore, at the end of S each nucleus would have 16 pg of DNA.

During G2 the cell continues growing and preparing for mitosis, but DNA content does not change: there are still 16 pg per nucleus.

Since nutrition just reduces the consequences of erosion and does not address its origins, it is usually a recurrent procedure. An agreeable setting lengthens the time between nutrient projects, cutting costs. On the other hand, a high rate of erosion might make nutrition unprofitable.

Sea turtles and rare and endangered birds alike depend on healthy beach and dunes systems. Important wildlife habitat areas that are endangered by erosion are provided by maintaining nourished beaches.
