Imagine that your government passed new laws that took away the rights of all people in your ethnic group. People in your ethnic group can no longer vote.They must move into poor-quality housing in rural areas. They cannot go to school with people of other ethnic groups. You are required to carry a passport everywhere you go. You aren't allowed to enter cities unless your passport says you have a job there.

List five ways your life might be different under these new laws.

Answers

Answer:

Your life would be like those people that live in an apartheid country. You have no freedom of movement like the Palestinian people do.

Answers

Answer:

an incidental or secondary product made in the manufacture or synthesis of something else.

Explanation:

Byproducts are chemicals that are released unintentionally in the production of something else. In this case, photosynthesis is a process where carbon dioxide is transformed into glucose.

What does magma erupt through to create volcanoes?​

Answers

When rock from the mantle melts, moves to the surface through the crust, and releases pent-up gases, volcanoes erupt. Extremely high temperature and pressure cause the rock to melt and become liquid rock or magma. When a large body of magma has formed, it rises thorugh the denser rock layers toward Earth's surface
Lava (magma that has erupted onto the Earth's surface) is visually mesmerizing – as the molten rock flows downhill, lava exposed to the air cools to a deep black color, while the molten rock beneath glows bright orange.This magma can push through holes or cracks in the crust, causing a volcanic eruption.
