Answer:
The disease is caused by the ciliate protozoan Ichthyophthirius multifiliis, commonly called ich or ick. Fish infected with ich typically develop small, blister-like, raised lesions (white spots) on the skin and/or fins.
Explanation:
I'm pretty sure this is true. Don't quote me on that lol.
I would say probably the age of the habitat
Answer:
B. Plant Growth
Explanation:
The dependent variable is the result in the experiment. It depends on the independent variable to occur. Hence, the word dependent :) In this situation, the light is the independent variable because it is the factor that the experimenter is changing. It is the only thing that the experimenter changes in the experiment. The resulting plant growth is the dependent variable because it depends on the amount of light to grow. Hope that makes sense!
Answer:
Abrasion
Explanation:
Mechanical weathering is generally called physical weathering where rocks are broken down physically. It means that the rocks are broken down into smaller pieces but the rocks' composition (chemically) is not changed.
There are different ways that rocks can be broken into smaller pieces physically and gravity helps can also cause it.
Abrasion is an example of mechanical weathering where rocks bump into each other and cause the rocks to breakdown because of the force of bumping into each other. Gravity plays a role when it comes to rocks on the mountain side.
When a rock on top tumbles down the side of the mountain, it bumps into other rocks along the way. Gravity is at play here because it pulls the rock downwards, causing it to tumble.
