Once hooked on the line, they are ensnared in the gear and soon drown. Other fishing practices can also incur large amounts of bycatch. Trawling can drown turtles that get caught in nets. Gillnets are staked to the ocean ...

Some kinds of fishing gear can be even more destructive when they become lost or forgotten in the water because they continue to catch animals, a phenomenon known as “ghost fishing.” This is particularly wasteful and destructive because the gear can ensnare tons of animals that aren't being harvested or used in any way. Fishing piers can be sites of ghost fishing as lures and lines become wrapped around pilings, where animals swimming by become trapped.Fish are not the only victims, however, as birds that dive into the water for prey can also get caught in the lines when they enter the water.

Answer:

The answers are:

Cell Wall:

Gives plant cell its shape
Rigid

Cell Membrane:

Acts like a skin.
More selectively controls what goes in and out of cell.
Is not rigid.

Explanation:

The question entails the structural and functional differences of the cell wall and cell membrane.
The cell wall is a rigid and strong layer that covers the outside of plant cells. It is absent in animal cells.
The cell wall is largely composed of cellulose, hemicellulose and pectin in plants and peptidoglycan in bacteria. The cell membrane, on the other hand, is comprised of a lipid bilayer.
The strong and complex network of cellulose renders the cell wall rigid; whereas, as it is made up of lipid bilayer, the cell membrane is flexible and elastic.
Unlike the cell membrane, which allows the movement of selective substances, the cell wall does not allow any substances to pass through.

Benefits of Microscopes

zhannawk [14.2K]

Answer:

See the answer below

Explanation:

The light microscope is able to produce images in their natural color because photons of visible light are utilized as a light source and color is a function of light. Both transmission and scanning electron microscopes are not able to produce images in their natural colors because they utilize beams of electrons to image specimens. They produce grayscale images instead because the regions of the specimen where electrons pass through are usually white while other regions remain black.
