What is the relationship between proto-oncogenes and oncogenes? hints what is the relationship between proto-oncogenes and oncog
Elan Coil [88]
Oncogenes result from turning on, or activating proto oncogenes. Proto oncogenes are genes that code for positive cell cycle regulators, so proto oncogenes code for proteins that turn on cell division. Proto oncogenes are normal genes, but when they are mutated, they become oncogenes.  Oncogenes are expressed too much, which makes them  turn on cell division too much, which is cancer.

how does distance from the ocean, ocean current, latitude, elevation, and relative location of mountain ranges affect the climat
7nadin3 [17]

Answer:

So many factors influence the climate. Some of them are ocean currents, latitude, distance from the ocean, elevation, etc.

Explanation:

The distance from the ocean influences the climate of the place. If the place is located on the coast, the climate will be colder and humidity will be higher.

Thanks to ocean currents the temperature can be changed. Ocean currents can low the temperature but also make it very high.

Latitude has an influence also regarding the temperature. Elevation, as it gets higher, the air above is falling, so the pressure decreases.

Regarding all the factors above, we can say that New York has hot summers, with high humidity and very cold winters, full of snow. Close to the river, the ground is muddy and going to the mountains, the ground is getting rocky
