Only shallow earthquakes abundant near the ocean ridges because the crust here is shallow as a result of being located where new oceanic plate is being formed. Here, movement is much simpler and involves the new plate material spreading out from the central ridge.
B. Velocity is correct because the truck movement is described with a magnitude and direction and the direction is constant.
Answer:
Ok so i will try my best to describe the answers:
1) a convection current is like a boiling pot of soup. the burner heats up the soup on the bottom. hot air always goes up because the molecules become more active, making them space out upward. the hot soup travels up through the center of the pot, and the cold soup up top travels down towards the edges of the pot to replace the hot soup that just moved up. the process keeps on going and going until there is no more heat, or until the burner turns off.
2&3) the sun makes everything warmer, so when the sun touches Earth's surface, it warms up the air around it. as soon as the air warms up, it goes up into the atmosphere, like the pot of soup example. then, cold air from the top moves in to replace the hot air. with so many molecules of air moving at one time, it makes gusts of wind during the movement. when it is really windy, that means that there is a lot of hot air moving up and cold air moving down. when there is no wind, that means that every molecule is where it is supposed to be, not disturbing one another.
I hope this helps :D
As activators that increase transcription initiation or decrease action of transcription initiation of related gene, transcription factors that bind to enhancers have an impact on genes thousands of base pairs distant.
Because the DNA between the enhancer and the promoter loops out, transcription factors bound to the enhancer can communicate with the basic transcription machinery directly. A few proteins that act as transcription regulators bind to enhancers, that are regulatory components located outside the gene they are meant to activate. DNA sequences known as insulators prevent enhancers from working. Insulators may work by creating chromatin loops that connect interconnected areas of genes and regulatory components.
