Does the water cycle, the nitrogen cycle, and the carbon-oxygen cycle play a role in ecosystem balance? Explain.
Anika [276]

Explanation: The water cycle is also known as the hydrological cycle. It describes how water moves on, above, or just below the surface of our planet. Water molecules move between various locations - such as rivers, oceans and the atmosphere - by specific processes. Water can change state. Nitrogen compounds found in cells include proteins. Nitrogen from the air is converted into soluble ions that plant roots can absorb. It forms part of nitrogen compounds in the plants, and is then passed from one organism to the next. It is returned to the atmosphere as nitrogen gas. This is the nitrogen cycle. The carbon-oxygen cycle is the process by which plants use carbon dioxide for respiration during photosynthesis and produce oxygen. During this process, carbon dioxide becomes part of the plant, and when the plant dies in a carbon-rich state it is possible for it to become a fossil fuel.

How can gel electrophoresis be used to help illegal poaching of great white sharks?
statuscvo [17]

Explanation:

Gel electrophoresis is one simple and cheap laboratory technique used in profiling. In this case, it can be used to identify Great White Sharks using their proteins or DNA. This way, even if the fish is completely mutilated into the meat, the species can still be identified helping policies to be enforced.

DNA or proteins of a sample of suspected meat is processed and passed through gel electrophoresis. The bands that form are then compared with a standard to check if the bands match. A match indicates that the meat is from a Great White Shark.

Does a moving magnetic field creat a megnetic field
faust18 [17]

Answer:

Explanation:

A moving charge causes a magnetic field and a moving magnet causes an electric field. If you change your frame of reference to that of the charged particle, the magnetic field disappears. Same is true for the magnet. Changing your reference frame to that of the magnet will make the electric field disappear.
