Answer 1

1) best answer is likely  f (DNA), but RNA can be found in Cytoplasm and else where.

2)  igneous rocks can be either intrusive (plutonic) formed by magma cooled within the earth, or extrusive (volcanic) formed by vulcanism with lava flow on surface of earth (check Wikipedia for  "igneous rock")

Good Luck!

2. cooling and crystallising from hot molten magma or lava.

Answer 4

NUCLEUS



Igneous rocks are called fire rocks and are formed either underground or above ground. Underground, they are formed when the melted rock, called magma, deep within the earth becomes trapped in small pockets. As these pockets of magma cool slowly underground, the magma becomes igneous rocks.

Igneous rocks are also formed when volcanoes erupt, causing the magma to rise above the earth's surface. When magma appears above the earth, it is called lava. Igneous rocks are formed as the lava cools above ground.
