Biology
1 answer:
BaLLatris [955]3 years ago
5 0

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.

In natural selection, what must be true of traits that are passed down through generation?
Radda [10]
Natural selection is the process by which individuals who are best suited to the environment tend to leave (on average) more offspring than others.

Evolutionary changes take place over many generations and through millions of years of natural selection. For the genes to survive, they must be among the strongest.

Which organism lacks tissue?
lara31 [8.8K]

Answer:

By definition, tissues are absent from unicellular organisms. Even among the simplest multicellular species, such as sponges, tissues are lacking or are poorly differentiated. But multicellular animals and plants that are more advanced have specialized tissues that can organize and regulate an organism’s response to its environment.
