An operculum covers and protects the gills.
Explanation:
An operculum is a flexible bony type of plate which protects the sensitive gills. When water is inhaled through the mouth it moves over the gills and is exhaled from below the operculum ( gill cover). gills remove oxygen that is present in the water and diffuse carbon dioxide from fish's body. Some fishes have spines which are located on the opiculum( gill cover) which acts as a defense mechanism to secure them from the predators.
First draw a table of sorts. Draw 2 arrows pointing in the same direction towards the table, labeling one as 1150N and one as 800N. Now, since both forces are exerted in the same direction, we can add the forces. So, 1150N + 800N, which is 1950N. There’s no weight and it doesn’t look like gravity is involved. If gravity is involved, just draw an arrow pointed down at the middle of the table, and a normal force pointed up towards the middle of the table. Hope this helps
