Explanation:
Sediment discharge was historically approximately 270 million cubic meters/year of suspended load and 130 million cubic meters/year of bedload. This has decreased 80% since 1850 and can be divided into three periods: historical period (pre 1900), pre-dam period (1932-1952), and post dam (1963-1982). Suspended sediment loads declined 43% between the historical and pre-dam and 51% from pre-dam to post-dam periods. The size of sediment also decreased drastically including a 72% decrease in the sand fraction. Most of this is due to dams on the tributaries acting as sediment traps primarily for the coarser sediments. Large-scale land clearing for agriculture contributed to increased sediment loads in the historic period.

D, correctly identifies the reactants and products of photosynthesis and cellular respiration. :)
2. Some common examples include soil erosion or drastically changed climate patterns, particularly where it concerns agriculture.
First, you can inspect the broth specimen. If the bacteria are aerobic, which need oxygen to live, the bacteria will grow in the upper part of the broth. Anaerobic bacteria will grow on the bottom part. The bubble can be produced if the bacteria do fermentation.
Doing gram stain microscopic examination also help much since knowing the gram classification and the morphology of the bacteria.
