Read the paragraphs and answer the question that follows.
Artemon [7]
We can infer of the two paragraphs that Geological movements are often hazardous when they happen quickly, and that the movement of plate boundaries does not always cause disaster.

The excerpt is telling us that "the <span>earthquakes caused a lot of damage, as well as dramatic changes to the local ecosystem", which is supporting the conclusion: "geological movements are often hazardous when they happen quickly." 
But is also telling us that "</span>The slip caused several rock formations and structures to develop cracks. However there was no large-scale disaster or disruption.", which is supporting the conclusion:  the movement of plate boundaries does not always cause disaster."

Plasma membrane of any cell including red blood cell is semi-permeable in nature as it is made up of lipid bilayer.

It permits the passage of certain substances across the membrane while it blocks other substances.

Gases, small uncharged or non-polar substances such as oxygen, carbon dioxide, et cetera can easily pass through the cell membrane of a cell.

Large or charged molecules such as proteins, sodium ions, potassium ions et cetera can not pass through the cell membrane. They require carrier proteins to pass through the membrane.

AlladinOne [14]

Nitrogen is returned to the atmosphere during the nitrogen cycle in a process referred to as denitrification.

<h3>What is denitrification?</h3>

It is a process whereby nitrogen becomes mineralized from nitrogenous compounds. In other words, it is the reduction of nitrates to produce elemental nitrogen which is returned to the atmosphere.

Denitrification is a microorganisms-driven process. The nitrates are made to pass through a series of reactions with intermediate products before finally leading to the production of elemental nitrogen.
