[Q]: What is the missing first step of the following process: - The movement is due to a combination of gravity acting on the sediment, and/or the movement of the fluid in which the sediment is entrained - Sediment transport occurs in natural systems where the particles are clastic rocks (sand, gravel, boulders, etc.), mud, or clay - The fluid is air, water, or ice - And the force of gravity acts to move the particles along the sloping surface on which they are resting - Sediment transport due to fluid motion occurs in rivers, oceans, lakes, seas, and other bodies of water due to currents and tides - Transport is also caused by glaciers as they flow -
****
[A]: Sediment transport is the movement of solid particles (sediment)

input: Please answer the following: What is the missing first step of the following process: - The receptors will lock onto a target cell using these chemical receptors on the surface, which docks onto the cell surface - The receptors then go into the cell - The receptors use it like a factory - The receptors take it over and make it produce thousands or in some cases millions of copies of new viruses - The copies come streaming out of the cell - The copies infect other cells to make more viruses, or they escape from the body and infect a new victim -
++++++++++
output: The flu virus has receptors, which are like viral Velcro, on the surface of the virus particle

Problem: Given the question: What is the missing first step of the following process: - The cells of the lung hold the air - They take in the air and remove the Oxygen - They inflate and all the bad air leaves through the mouth - They do it all over again.
++++++++++++++++++++++++++++++++
The answer is:
They expand to take the air in

Problem: What is the missing first step of the following process: - The sediment breaks down into small particles - Wind or water picks up the sediment - The sediment travels along the same route as the wind or water - The sediment is deposited at new locations by the wind or water - The sediment is picked up again by new wind or water - The sediment travels further - The sediment is deposited again in a new place.

A:
Sediment settles in a place due to gravity
