Alist of the cell fibers from largest to smallest would read: 1. microtubules, intermediate filaments, microfilaments

A list of the cell fibers from largest to smallest would read:  

1. microtubules – is a microscopic tubular structure that is present in numbers in the cytoplasm of cells. These are usually aggregated to form complex structures. 

2. intermediate filaments – are cytoskeletal components that is usually found in the cells of vertebrate species and other organisms like plants, fungi, unicellular organisms. 

3. Microfilaments – are filamentous structures that can be found in the cytoplasm of eukaryotic cells and it will form part of the cytoskeletons. They are composed primarily of polymers of actin. But in cells, they usually interact with other proteins.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.

is this a psat question, if so do not cheat try your best.
