D.A forest decimated by an avalanche
Answers
The correct answer is (b) A forest cut down by a logging company.
The most common method of logging is clear cutting because it is economically profitable. When a logging company use clear-cutting to cut down the forest, they cut each and every tree by tools in such a way that there are very least chances that a whole forest will recover.

Answer:
Hi!
- Epithelial cells (I believe)
- Nervous System
- Skeletal System
Explanation:
- Epithelial tissue helps cover your "exterior sources". Therefore I'm pretty sure the first one is Epithelial cells.
- The Nervous System has to do with sense of feeling or sense of touch mostly. The Nervous System controls everything you do! ex. touching a table uses the nervous system.
- The Skeletal System helps your body move and supports a lot of different things in your body. All of those other options are not correct just because they do not support. Here is what I mean in the shortest way possible:
- Circulatory- has to do with your lungs
- Lymphatic- involves a network of vessels
- Excretory- elimination of waste
Therefore these are your answers #1, #2, and #3.
Hope this helps!
